[PHP] PHP 5.2.17 zend_mm_panic Called

[Bruce Bailey]

Hi

I recently upgraded from PHP 5.2.3 to PHP 5.2.17.

After that, some of my pages keep failing with either Segfaults or calls to 
zend_mm_panic.  My gdb backtrace shows:

[PHP] 'dl() is deprecated' Error in PHP5.2.3

[Bruce Bailey]

Hi

Can someone explain to me why I'm getting the 'dl() is deprecated' error? 
I'm running PHP5.2.3 and I believe that I have the php.ini settings correct:

error.log:[2010-08-24T13:38:53] PC Error: dl() 
[function.dl]: dl() is deprecated - use extension=test.so in your 
php.ini


bash-2.05b$ php --version
PHP 5.2.3 (cli) (built: May  4 2009 16:23:02)

bash-2.05b$ php -i | grep -i safe
Thread Safety => disabled
safe_mode => Off => Off
safe_mode_exec_dir => no value => no value
safe_mode_gid => Off => Off
safe_mode_include_dir => no value => no value
sql.safe_mode => Off => Off


bash-2.05b$ php -i | grep -i dl
enable_dl => On => On

I thought that 'dl' wasn't deprecated until version 5.3.x

Thanks in advance,

Bruce

  

[PHP] still having trouble with time-stamp subtraction two mysql fields

[Bruce Gilbert]

Hi there,

I am still attempting to get a display of the result of my two
timestamp fields subtracted from one another in minutes and hours if
needed. This is for a form and the timestamps are recorded when a user
logs in [login_timestamp] and when the form is
submitted[submit_timestamp]. The display still doesn't appear to be
accurate and for some reason the results are displayed three times for
each record underneath the results for one person. So it looks
something like.

Tom Thumb
Answer 1
Answer 2
Answer 3 etc.
[time 1]
[time 2]
[time 3]

Sally Smith
Answer 1
Answer 2
Answer 3 etc.
[time 1]
[time 2]
[time 3]

Bob Jones
Answer 1
Answer 2
Answer 3
[time 1]
[time 2]
[time 3]

time1,2,3 being for Tom Thumb, Sally Smith and Bob Jones respectively.

My entire code for the form looks like this.



Exam Results



exam results

Candidate Name

{$row['name']}";
echo "Section 1";

   for ($i =1;$i<9;++$i) {
echo "{$row['Answer'.$i]}";
  }
echo "Section 2";

echo "{$row['Answer10']}";
echo "Section 3";

echo "{$row['Answer11']}";
echo "Section 4";

echo "{$row['Answer12']}";



$sql_timestamp = "SELECT
TIMESTAMPDIFF(SECOND,submit_timestamp,login_timestamp) as cTime FROM
Responses LEFT JOIN Candidates USING (user_id)";

$result_timestamp = mysql_query($sql_timestamp);
if (!$result_timestamp) {
echo "Could not successfully run query ($sql_timestamp) from DB: "
. mysql_error();
exit;
}
while($row = mysql_fetch_assoc($result_timestamp)){
  $formatted_completion_time = formatTime($row['cTime']);
  echo "Completion Time:\n";
  echo $formatted_completion_time;
  echo "";
}

}
mysql_free_result($result);



?>





and my function code for the subtracting of the two fields is here:



any assistance that can be provided is greatly appreciated.

I found out the problem.the value in (user_id) in the two tables has
to be the same. That is why the Query wasn't working.

I still am not getting the desired result though. Something that
should be displaying as five minutes displays as -117 minutes

My current code.
$submit_time = strtotime($row['submit_timestamp']);
$login_time = strtotime($row['login_timestamp']);

$completion_time = $submit_time - $login_time;
$completion_time /= 60;

$formatted_completion_time = floor($completion_time );

echo "Completion Time:";
echo $formatted_completion_time;
echo " minutes";
echo "";

Re: [PHP] determining time difference between two timestamp fields.

[Bruce Gilbert]

yea, not sure why my Query isn't returning a value though? If I don't
use date(), what should I use?

the SQL for the timestamps looks like this.
`login_timestamp` datetime NOT NULL default '-00-00 00:00:00',
`submit_timestamp` timestamp NOT NULL default CURRENT_TIMESTAMP,

sorry for the top-posting, but I think you have to in gmail.

Re: [PHP] determining time difference between two timestamp fields.

[Bruce Gilbert]

the resulting output with that code is a little weird. I get September
3, 1970 2:39:32pm

I think part of the problem is my Query. When I run it in PHP MyAdmin
I get a null value for login_timestamp even though there is indeed a
timestamp there. The Query again is:

SELECT 
Responses.editor_name,Answer1,Answer2,Answer3,Answer4,Answer5,Answer6,Answer7,Answer8,Answer9,Answer10,Answer11,Answer12,submit_timestamp,login_timestamp
FROM Responses LEFT JOIN Candidates USING (user_id)

login_timestamp is in a table called 'Candidates' and submit_timestamp
is in a tables called 'Responses'.

thanks for all the help to this point.

Re: [PHP] determining time difference between two timestamp fields.

[Bruce Gilbert]

probably not fully understanding what I need to do.

I am trying this.

echo "Completion Time:". date('F j, Y
g:i:sa',strtotime($row['submit_timestamp']) -
strtotime($row['login_timestamp']))/60 , "";


but just returns a zero value.

Re: [PHP] determining time difference between two timestamp fields.

[Bruce Gilbert]

Here is what I currently have.

echo "Completion Time:" .
(strtotime($row['submit_timestamp']) -
strtotime($row['login_timestamp']))/60 , "";

this gives me an output of 21235172.75

not sure what format that is in? I was hoping for something like 60
minutes, 30 minutes etc. Don't need the days or seconds. The MySQL
timestamp is in this format.

Thanks. I know my syntax isn't quite right, but is this close to what

[PHP] determining time difference between two timestamp fields.

[Bruce Gilbert]

Here is the situation. I have a form which sets a timestamp when a
user logs in using UPDATE in SQL. The field is called
'login_timestamp' and is in a table called 'Candidates'. I have
another timestamp which is set when a user submits the form data into
the DB and it is called 'submit_timestamp' . What I want to do is
determine the amount of time the user takes to complete the form by
subtracting the 'login_timestamp' time form the 'submit_timestamp'
time. I am using SQL to extract the data here.

$sql = "SELECT Responses.name,Answers,submit_timestamp,login_timestamp
   FROM Responses LEFT JOIN Candidates USING (user_id)";

and then to display the timestamp in readable form.

echo "Completion Time:" . date('F j, Y
g:i:sa', strtotime($row["login_timestamp"])) . "";

so I need to know how to subtract from two timestamp fields, two
different tables and come up with the difference in minutes.


thanks.

[PHP] php - page flow issue...

[bruce]

hi.

got a situation for a potential page that i'm playing with. i'm trying
to figure out how to implement it, and the best/good approach to this.
i'm actually considering integrating this kind of process within a cms
(joomla/mambo/cmsms/etc..) but right now, this is in the initia
thought stage...

if you have a thought/page that i can lok at that's actually
implementing this kind of flow.. i'd really like to see it..

so, here goes...

===

--need to figure out a way to have the user invoke an action on the
top section of
 a page, and have that action, trigger an action on a separate part of the page


example:

i have a page that looks something like this:

 +---+

 initial navbar stuff (always shown on the page)

 
   stateList (select/option)
 


 +--+
based on the user
 selected state {
   based on the user{  < based on
the selected state
   user state   {
{
  "cancelBTN"  "submitBTN"
   

 +--+

(page1)
 +---+

i need to have a way to have the user select a "state" from the
 statelist, and to then have the tbl/section of the site under
 the "cat" form, generated, based on the selected state.

at the same time, i need a way to have the user select an item
 from the "dog" tbl, and to have the user select the
 cancelBTN/submitBTN, with the app then generating the
 subsequent action/logic. the page below, is a kind of
 example of what i'm thinking of...

 +---+

 initial navbar stuff (always shown on the page)

 
   stateList (select/option)
 


 +--+
based on the user
 selected state, and the cat1.submitBTN

  confirmation section
  {
   based on the user selection from page1/cat1{ <<<
based on the previous
   cancel/submitBTN   {
cancel/submitBTN

  "cancelBTN"  "submitBTN"
   

 +--+

(page2)
 +---+


i can see a couple of ways of accomplishing this...

1) i can have a page of logic, that is composed of a bunch of
 logic, that is basically an "if block", that generates/displays
 the different parts of the page, based on the user actions of
 the preceding pages/sections (the cancel/submitBTNs). this approach
 would essentially require the entire page to be regenerated with
 each BTN selection.

 the logic would generate/invoke the correct page elements based
 on the user selection/action of the previous page/section.

2) i could possibly utilize div/frames, to allow the content in
 the targeted div/frame to be updated/redrawn/regenerated based
 on the user action/selection of the previous page/section...

 this might be able to be done (not familiar with the
 underlying processes to know if this is doable/suitable)
 or even a goof approach..

 would this apaproach still require the entire page to be
 redrawn? or just the portion that's in the targeted
 div/frame...

3) somehow invoke javascript/ajax function/features/logic,
 to allow the actions/interaction to occur, such that the
 content in the targeted div/frame is modified, without
 requiring the rest of the page to be modified...

 i have no idea if this is doable, or what this would mean,
 or involve, or how to apprach this..


or, there might be a different way of accomplishing this
 that i haven't even thought of...

any example sites/docs/code would be greatly appreciated...
heck, i'd even be glad to see an actual site/code that
demonstrates how this can/might/should be implemented!!!

RE: [PHP] How to Delete the parent node, and child nodes/leafs for a db/tbl in php

[bruce]

hi ash...

thanks for getting back to me.

my situation isn't that complex, but i'm looking for an efficient method.

i've got a start tbl
 universityTBL

the universityTBL can have either
 schoolTBL, or
 deptTBL
as the next child tbl

 the schoolTBL will have
 deptTBL
 as the child tbl

 the deptTBL wil have
 classTBL
 as the childTBL...

to get around some of the headaches of this approach, i maintain
 a mapTBL where i have the parent_uuid,child_uuid as entries
mapTBL
-parent_uuid
-child_uuid

so my issue is that if i have a given parent_uuid, that i want to
 delete, as well as the associated leaf/nodes of the parent..
 how can this be accomplished?

you can't just start to delete the parent_uuid, as you completely miss
 the underlying/associated nodes/leafs for the parent_uuid...

thoughts/comments/etc...

Well if the tables truly have a relationship, then no PHP is necessary.

I assume that to connect the 'parent' row with the 'children' rows of
the secondary table you've used an identifying field. For example:

users table:
user_id
forename
surname

emails table:
email_id
user_id
email_address

So in the above example, a user on the users table could have several
entries in the emails table for each email address they have.
emails.user_id will match up users.user_id so you can run a query like

DELETE FROM emails WHERE user_id=id

Is this any help?

[PHP] How to Delete the parent node, and child nodes/leafs for a db/tbl in php

[bruce]

Hi.

I've got a situation where I have a couple of tables. The relationship
between the tables is one of parent/child. I'm trying to figure out the best
approach to being able to delete the associated children in the child tbls,
of a given parentID in the parentTBL...

I've checked into various sites/articles on the 'net.. but i'm not sure how
best to accomplish this...

I'm using php as the interface language to the test tbls..

Any pointers/articles/test code (code/schema) would be helpful...

Thanks

[PHP] php/sqlite3

[bruce]

hi...

i've got an issue where i'm trying to incorporate sqlite3 into my php.

i'm running fedora 9, php5.2.9.

the php app was  installed using the tun install process...

i know the docs say that php5+ is supposed to have sqlite incorporate
natively...

however, on this box, it doesn't! when i do a phpinfo(), i get the pdo
stuff, but not the sqlite.

i went ahead and followed a thread on the php.net that walked through adding
sqlite3, using the phpize, and managed to create the sqlite3.so...

the phpinfo now has a sqlite section, with a sqlite3.extension_dir that
points to the dir that contains the sqlite3.so..

however, when i run a test app using "sqlite_open", i'm getting an error
saying that the "sqlite_open" is undefined...

so... my question..

how the heck can i resolve this issue!

thanks..

This would be a nice and fast solution, but unfortunatelly, it's like
that the C programm needs to surveilance the hardware all the time
(controlling values,...) hence, it would run more as a "daemon".

[PHP] need someone to bounce some thoughts with for a project!

[bruce]

hi list...

sorry to post here, but i figured you might be able to help...

i'm working on a project, that deals with building a crawler, and i'm
working out the details for the mgmt app for the crawler. i'm currently
looking at how to deal with the status/actions of the crawler, and how the
different components of what i call a job would be compiled, and reported
back to the batabase.

i'm wondering.. is there anyone on this list that i might be able to email
with, talk to about this.. while i've got a few ideas, never hurts to be
able to talk/share thoughts with others..

thanks much!

basically:
 my methodology is that i create a batchfile
  (the batchfile consists of the underlying apps that do the crawling)
 each batchfile can be run by multiple jobs (as required)
 i'm creating the piece of the mgmt app that will track/manage the jobs
 i'm lookin at being able to track the health of the 'jobs' as they run

 i'm considering the 'actions' as well as the 'status'

 i'm thinking of:
disable/enable
stop/restart
waiting to start
running
complete/finished

 status might have things like:
success/complete (no errs at all)
complete/errs (ran through all the scripts, but some had errs)
failed (didn't complete all the scripts)
etc...


 i'm looking for someone i might be able to talk to, or exchange a few
ideas/emails with on this..

thanks much!


ps.. and yeah.. the web app is all in php!!!

RE: [PHP] Periodic Actions in PHP?

[bruce]

hi...

is this a php/web based app...
are the users using the chat function via the browser..
if this is a browser/web app, are you looking for a way for the
 php web app to refetch the textfile... i would assume so...

have you figured out a rough architecture/design for your app..
in your design, you're going to need to figure out how to
 accomplish updates to the text file, and when you do, you'll
 also have figured out how to do the reads...

i'm assuming that you don't want a continuously running thread
 for your php/web app.. ie one continuously, never ending loop...
 -so you'll have the user add some text, the app will write this to
  a file..
 the user will either select a refresh kind of btn, or your
 app will have to implement a refresh process, which will then
 fetch new/updated data from your files..
 etc...

If you're on Unix then look into using cron. Type the following at the
command prompt to get info on cron:

man 5 crontab

Cron tasks can be scheduled at most once per minute. And if you're
using Windows then I believe the equivalent would be task scheduler,
but I've no idea how you would go about using it.

A little while ago... (in a land far away!!).. Someone posted some questions

RE: [PHP] Web application design considerations - a good reference ?

[bruce]

hi angus...

You're probably going to get a lot of different approaches to this one! as a
long term/time developer in a past life.. In my humble opinion, a reasonable
approach is to start by laying out the key things that the app has to
accomplish, and then to break this down into a list/sublist until you get a
comprehensive list of things that your app should do... You can put these
items into buckets to help keep track of what you've thought about. Each
bucket can then be aligned with a given section of your website as you start
to get into the UI/Look-feel of the site.

One of the most important/key things you can try to do, is to find someone a
few people, who are willing to act as a sounding board for the different
aspects/parts of your project.

Once you've gotten the list, and a basic UI/Wireframe kind of overview (and
you can use word/openoffice/etc.. to create a wireframe) you can then have
something that you can kind of look at, kick the tires so to speak of what
you're envisioning the app to be. This overall process forces you to really
think about what the app should consist of, as well well as how it's going
to be put together, how the different sections are going to flow...

Once you all of the above, you can focus on the workflow/processes of the
app. What happens when the user does X, who gets notified, when the user
does Y, that kind of thing...

There's a lot more, but this should get you started!!!

Good luck!

?


Hi all.

I'm working on a PHP project for my own personal business use. It will
handle billing and invoices as well as payments and time management,
bookings, appointments and a few more. I may add things like personal
messaging between the various users and a customer login to check on the
progress of their accounts.

It is a big project and will probably take a year or so to complete in my
spare time.

I have made a couple of starts but I have no experience in creating such
large applications and I find I often end up with spaghetti code. I've tried
using session variables to keep track of where and what the program is doing
but there are so many permuations and combinations I found myself writing
endless streams of if's, and's and or's just to figure out what page to
display.

The code is not the probblem for me...it's the flow and organization of the
code.

Can anybody point me to a good book or tutorial that lays down the
principles and gives some suggestions for integrating the many subroutines
of a large application? I want to make the code readable and logical in its
flow, and avoid repetition of code segments.

Much appreciated.
Angus

Hi Bruce,

He's spawning child processes to handle the audio changes. These
processes are separate processes from the PHP script being run by the
webserver. However, they are children of the PHP script process since
they have been started by the PHP script via popen() or proc_open(). His
problem is that when the user changes page mid load, or shuts down the
browser, the PHP script (the parent) is killed off by the webserver, but
the child processes, sox and lame, continue to run. This ends up
polluting CPU/memory with useless processes. What he wants is to have
these processes also die. So by using proc_open() he can retrieve the
output from the processes he has started and send that to the connected
browser in chunks, but also detect if the browser has dropped its
connection in which case he can manually kill of the child processes
that aren't being killed automatically. HTH.

Cheers,
Rob.

The PHP session controls the popen() or proc_open() session. The PHP
session can detect that the user has aborted and then shutdown the
popen() or proc_open() processes.

but if the user is using a browser session... which has a web server

Use something else to pass the data back to the user... popen() comes to
mind or proc_open(). Then disable auto abort on user disconnect via
ignore_user_abort(). Then after sending periodic data chunks, check the
user connection status via connection_aborted(). If your script finds
that the user has aborted, then kill all the processes in the pipeline
from the PHP script before finally aborting the PHP script itself.

when webpage download is canceled


sent this before, don't know if it went through... someone please reply if 
it went, even if they don't know answer?...

so here's the scenario..

I have a site that uses php with a database to offer sound files to
users using streaming methods.

the request page has options, allowing the user to modify the sound
file in various ways, before having it sent to them

Here's the problem:

The method i'm using to feed the data to the user is to run the source
file through various piped commands, with the resulting audio being
dumped to stdout, and then using passthru in php to get that data to
the enduser.

here's an example, for serving an MP3 with its pitch/speed changed by sox:

passthru("lame --quiet --decode \"" . $in_file . "\" - | " .
 "sox -V -S -t wav - -t wav - speed " . $speed_factor . " | " .
 "lame --quiet " . $lame_params . " - -");

This works just fine, except the problem is if the end user aborts the
transfer (e.g. stops playback in the media player, cancels download of
the mp3, whatever) then it leaves behind both the sox process and the
decoder LAMe process along with the sh that's running them. the only
process that exits is the final encoding lame process. If the sound
file runs to completion, everythign exits properly.

But this obviously means enough "cancelling" of downloads means the
server ends up with a huge batch of stuck processes! And I even tried
simply killing the 'host' sh process, and the lame and sox processes
remain anyway. The only way I've been able to deal with this is
manually killing the lame and sox processes directly.

is there any way I can make this work, such so that if the user
cancels the transfer, all relavent processes are killed rather than
just the single process that's feeding output into php?

4 for the

this computes every 'X' month, on the 'date:hour:min' using
strtotime(interval, secs)
need to include logic to cut limit future month to the 'end date' of the
 month. don't want to roll over into the next month.. ie, if the date
is jan 29,
 and the next feb only has 28 days.. stop at jan 28...
need to incorporate leap year checks, etc...
-gives every Month at the current 'date:hour:min', based on the above
 logic/restrictions/implementation...


user selects every 'day' (mtwthf)
covered by the weekly section.. (no need for a separate selection)

user selects 1st of month
covered by the monthly section (no need for a separate selection)

user selects 'last-of-month'
 user selects 'X' as the numeric interval
(if 'X' is blank, app defaults 'X' to 1)
  app gets the startime in linuxsecs, based on user input, or 'default
now()'
  app determines the month based on the computed secs data
  app app then detemines the last date of the computed month
  app uses date(-t,secs) to get date...
  app gets year:month hour:min from the startime/linuxsecs
  use the date, and the year:month and hour:min to get the
final eventsecs for the last-of-month

This is confusing.  When and where do you need to "be able to determine
when the future events/occurances are"?  You need to display this after
the user schedules the app/process or an admin needs to login and see
this at any given time?

Regardless it is easy with the PHP time/date functions.  Once you've
collected and stored the start/stop times and interval, something
similar to:

$interval = "1 week";

$next = $start_time;
while ($next <= $end_time) {
$next = strtotime("+$interval", $next);
echo date(DATE_RFC822, $next) ."\n";
}

RE: [PHP] Re: Numerical Recipe - Scheduling Question

[bruce]

hey shawn...

on the strtotime function... it appears to simply take intervals of a string
type..

is there a way to have it take intervals of the number of secs? or is there
another time function that takes the current date/time, and allows you to
add an interval in secs?

thanks

RE: [PHP] Re: Numerical Recipe - Scheduling Question

[bruce]

hey shawn...

strtotime (or something similar) might just work

i'll always know the interval... which can be used to compute the nexttime,
which then becomes the next starttime...

i'm assuming there's an equally simple way to find the last day of a given
month if i choose that as an interval as well..

for my initial needs.. this might work.. until i free up time to actually
craft a more generic solution, independent of the underlying language/os..

thanks



for next month.. and the start

RE: [PHP] spawning a process that uses pipes - doesn't terminate when webpage download is canceled

[bruce]

Hi Flint.

Not sure if you have a solution to this yet, or if I fully understand! But
if your issue is basically that you have a situation where you might have
orphaned processes that never finish and that are consuming real resources
you could have the app get/monitor the process ID for each process you
create, and then simply periodically check to see if that process is in a
run state.

Bow, if the situation is one where the user aborts the transfer process, and
the underlying processes are still 'running' then I would still think the
above appproach would work, but you'd have to have your app keep track of
when the user 'kills' the download process..

But are you sure the orphaned processes are consuming resources, or are they
zombie processes, which are resident in the process tbl, but aren't really
consuming resources... sombie processes will (should) eventually be dealt
with by the operating system...

regards

RE: [PHP] continue working after finishing up with the http client

[bruce]

hi tom...

if i understand your state diagram/workflow process. your server repsonds to
the client request, with two actions...

 action 1) return data to client relatively fast
 action 2) insert the data into your cache (or whereever) which takes
time...

is this correct?

do you have to somehow use the 'new'/updated cache data in the future
actions with the client...

it might be possible for you to have a setup, where you have an external
cron process, or other continually running process that does the cache
insertions

it is a web app.

let's say for example that we're processing an ajax query. say we can
normally generate and deliver the response to the client quickly but the
speed depends on a cache with a relatively low miss rate.

now, when we get a cache miss, imagine that generating the client response
from scratch takes significantly less time than generating and inserting the
new cache entry corresponding to the query. so we want to send the response
to the client and then process the cache entry.

without getting into whether or not this cache design makes sense, my
question in this example is: what options are there for ending the http
transition and then continuing on to do the cache update work?

[PHP] Startup Stuff in the san Francisco/Bay Area

Hi guys...

Before you start flaming/shouting.. thought I'd post this here, as I'm at my
wit's end, and this might help others as well. And yeah, this has nothing to
do with solving a php coding issue!!

I'm trying to figur eout if there are guys/gals/groups/etc.. of developers
here in the San Fran/San Jose/East Bay area that are into the pure sweat
equity startup thing. I'm simply looking to find if there are people/groups
that you might know of, how are into creating/starting projects. I've done
the Craigslist Posting thing, with no real luck, so I thought I'd post this
here...

Feel free to get to me off line to reduce the amount of time on the list for
this thread, unless you think it might be useful for others as well...

if you really want to get to the real low level details of an app...

unless you're dealing with an app that's seriously crunching, and extremely
sensitive to returning data to the user's browser in a timely manner, you
should write all replies back to a db/tbl... this would allow you as the

I'd avoid using @ in favour of turning the errors off in your php.ini
or .htaccess, as there's no chance of you missing a statement here or
there.  It's generally accepted practice to have errors and warnings
turned off on a live server, and to only use them on development
servers.

Because that's how most people came by their opinion of goto? How did
you come by your opinion of goto? Oh yeah, your momma! Here let me open
your eyes a bit... I've done a grep on the PHP 5.2.9 source code, Apache
2.2.11 source code, and MySQL 5.1.33 source code for use of goto:

PHP 5.2.9: http://pastebin.com/f6b88957

   Apache 2.2.11: http://pastebin.com/f2c7f5d93

   MySQL 5.1.33:  http://pastebin.com/f4441a891

It would seem that goto has a lot of use in modern code. Just because
someone tells you something, doesn't mean you should believe it at face
value. Goto has many important uses in programming. The goto that was
spurned is not really the goto in use today. The goto in use today
generally has scope within a well defined context such as a function.

Cheers,
Rob.

[PHP] Need Help! - Looking over a wireframe doc...

[bruce]

Hi..

I'm playing around with creating an app to allow users to
add/checkin/checkout docs from a web based app. The backend will tie into
SVN as a repository.

The app is intended to be a php/mysql/linux app.

I'm trying to find a few people that I might get to take a look at the
current doc(s) I have and give me some comments/feedback...

The goal of the app is to allow a user to register, and then select the
given doc he wants to work on, as well as the given workflow phase. This
allows the app to kind of restrict the access rights a user has to the doc,
based on where in the workflow the doc is..

Get to me offline if you're interested in taking a look.

thanks

hmmm...

however, if you put together a number of really skilled c/c++ (whatever)

what oracle is going to do with the current tree...

of course i'd have a better chance of winning the lottery!! but stranger

Ahhh, I love the smell of condescension first thing in the morning. BTW I am
a MySQL developer thank you. A developer does not an owner make. Where do
you get the idea that Oracle would put this to a democratic vote?

You can post job requests for stuff like this on elance.com,
rentacoder.com and I'm sure hundreds of other places.

I don't think this list is the appropriate place for it really but
that's just my opinion.

[PHP] Out of the blue question..

[bruce]

Hi Ladies/Gents of the list...

I've got an issue/question and figured I'd fire it to the list.

Over time, I've had a few projects that I've worked on, where I've required
someone with skills way beyond mine for a given area. And rather than spend
hours trying to figure it out, I've sometimes hired someone to aid for a
very short amount of time..

The issues have ranged from serious db optimization, to server security
issues, etc...

I was wondering, I'm assuming that other developers here have had similar
issues. Has anyone thought about doing a group hire of someone with the
advanced skills to solve the particular issue for the problem domain.

IE if enough people have, or know you're going to have mysql questions...
Then we find someone who's good/skilled and more or less have that person on
retainer for the group. This of course depends on how many people would want
to use the person's skills, and how often we'd need the person, and other
issues...

I figured that I'd post here to see what the list thinks/thought.. etc...


thanks

ps. And no, I have no one in mind, and this isn't an around the way

Unless the PHP development process has become a dictatorship, I'm
pretty sure more than one person decided it was a good idea before
putting it in the mailing list rules.

Could you show me the signed agreement list. While it's convention on
this list, it's certainly not something everyone agreed upon.

This sounds like something Subversion (SVN) is suited for. Three
repositories in the same realm: dev, test, prod. Slap a web front-end
on it like Polarion's "svn-web" (for JSP/Tomcat) and you're in
business.

[PHP] Workflow app for software

[bruce]

Ladies/Gents...

Hi. Trying to get some input to a web based app for dealing with managing
software apps/scripts.

Basically, i'm envisioning a system where people register/signup, and then
check in/out apps for development/testing/production... I need a way of
dealing with users, assigning/accepting roles for the users, and to manage
the flow of the "file" as it moves through the basic
"development/testing/production" process. i'd like to have a database
backend, combines with some kind of source/file reqpository...

I've seen things like knowledgetree, owl, etc... but figured I'd get input
from here. So, any thoughts to open source apps that you guys have actual
experience using??

Thanks

Subject: [PHP] Regex


Hi,

 

Brand new to regex. So I have a cli which runs a regex on users input,
to make sure that only 0-9 and A-Z are accepted. It should strip
everything else. My problem is that when you press control-Z (on
Windows; I have not yet tested this on linux, and I will, but I would
like this to be compatible with both OS's) it loops infinitely saying
invalid data (because of the next method call, which decides what to do
based on your input). So, here is the input code. Is there a way I can
ensure that control commands are stripped, here?

 

 

 

 

 

public function getSelection() {

 

$choice =
$this->validateChoice(trim(strtoupper(fgets(STDIN;

return $choice;

 

}

 

private function validateChoice($choice) {

 

$choice =
ereg_replace("/[^0-9A-Z]/","",$choice);

return $choice;

 

}

 

 

 

I have tried a ton of different things to try and fix this. Tried
/\c.|[^0-9A-Z]/, and many variations of \c and the [^0-9A-Z], to no
avail. I also tried using both preg_replace() as well as ereg_replace().
I spent a lot of time on the regex section of the PHP manual, but I am
not finding anything. Any advise on how to accomplish this?

 

 

 

Thanks,

 

Jesse Hazen

start with an existing framework/app that already kind of works with
modules/apps on a system, and then modify it to meet my needs...

[PHP] quick question - need a site i can more or less copy from

Hi...

Working on a test app, and I need a web interface to test/view the
underlying information. Looking for (hopefully) quick pointers/suggestions.

I'm dealing with a number of cli web crawling apps that return data. I'm
trying to find a quick app that I can modify the db schema, as well as some
of the underlying logic to display my data.

my returned data consists of:
 university
   school
 dept
  class
   classname
   classID
   classdescription
   classA
   classB
   faculty


The above is a represenation of the levels of data. I'm looking to have
multiple tbls, each of which links to the child tbl...

I'm not a web dev, and i'm looking for some sort of web app that i might rip
apart/modify so i can start to be able to view this data on a web app..

i'm currently looking through sourceforge/freshmeat/etc...

thanks...

when dealing with windows.. or any file/pathname.. you can't simply

haven't done it for awhile.. but i believe you need to explode/derive the

You might have something there - never really thought about how windows

The actual path is "c:\Program File\Gammu 1.23.91\bin\gammu.exe"
I'd used "c:\Progra~1\Gammu~1\bin\gammu.exe"

RE: [PHP] whoami explanation

[bruce]

hi pj...

single quotes are entered via the key directly left from the "return/enter"
key on most/all qwerty keyboards...

the 'backtic' is normally the shift '~' key... the key, right to the left of
the '1' key... in the upper left position of the keyboard...

[PHP] RE: file locking...

[bruce]

Hi Dennis...

Thanks for the reply... Here's my solution up to now.. might change in the
future...

The problem:
App has a bunch of clients that need to get a separate/unique list of files
from a master server app. The files are created by the master server
process, and reside on the filesystem behind the server process. (this is a
client/server based app. client sends a request to the server.. the backend
operation of the server fetches the required files, and returns them to the
client app.)

A key issue is that I don't want to run into potential race conditions,
which would result in a given client never being served the files it's
trying to fetch.

Potential Soln:
1) Invoke a form of file locking, with each client processes waiting
   until it gets its lock.
2) Invoke some form of round-robin process, where the master process
   puts files in different dirs, so each client can have a better
   chance of getting a "lock" for the different dir..

Final Soln: (for now)
I decided to cheat!
I realized that since each client process is essentially unique, I can
create a uniqueId (uuid) for each process. Remember, the client app is
hitting the master server/file process via a webservice. So I have each
client send it's uuid to the master server via the webprocess. this
information is appended to a file, which gives me kind of a fifo approach
for creating unique dirs for each client. the server (on the backend) then
reads the fifo file, for the uuid. in getting the uuid for the 'client', a
master cron process then reads the fifo file, and for each uuid in the file,
creates a tmp dir for the uuid. the master cron process then populates this
dir, with the required files for the given client.

on the client side, the client loops through a wait loop, checking to see if
anything is created/placed in its tmp 'uuid' dir.. if files are there, it
fetches the files, and proceeds..

This approach ensures that a client would never run into a situation where
it might never get files where files are available for processing. in the
event there are no files, the client simply sleeps until there are files..
in the event a client requests files via the sending of the uuid, and the
client dies before getting the files, but the master cron had already placed
them in the uuid dir.. there will be a cleanup process to reabsorb those
files back into the system...

thanks to all who gave input/pointers!!

My silly thoughts...

Main process creates temp/scratch directories for each subprocess;
spawn each subprocess, passing the directory path to it;
main process then just loops over the files moving them, one at a time,
to one of the temp/scratch directories, probably in cyclic order to
distribute the load;
when main/input directory is empty, sleep then check again (or, if the
OS supports it -- use some directory change notification) for new files.

Each subprocess only sees its files in the applicable temp/scratch
directory.

hi rob...

what you have written is similar to my initial approach... my question, and
the reason for posting this to a few different groups.. is to see if someone
has pointers/thoughts for something much quicker...

this is going to handle processing requests from client apps to a
webservice.. the backend of the service has to quickly process the files in
the dir as fast as possible to return the data to the web client query...

Would I be right in assuming that a process grabs X of the oldest
available files and then begins to work on them. Then the next process
would essentially grab the next X oldest files so on and so forth over
and over again? Also is the file discarded once processed? Would I be
correct in presuming that processing of the files takes longer than
grabbing the files wanted? If so then I would have a single lock upon
which all processes wait. Each process grabs the lock when it can and
then moves X oldest files to a working directory where it can then
process them.

So... directory structure:

/ROOT
/ROOT/queue
/ROOT/work

Locks...

/ROOT/lock

So let's say you have 500 files:

/ROOT/queue/file_001.dat
/ROOT/queue/file_002.dat
/ROOT/queue/file_003.dat
...
/ROOT/queue/file_499.dat
/ROOT/queue/file_500.dat

And you have 5 processes...

/proc/1
/proc/2
/proc/3
/proc/4
/proc/5

Now to start all processes try to grab the lock at the same time, by
virtue of lock mechanics only one process gets the lock... let's say for
instance 4 While 4 has the lock all the other processes go to sleep
for say... 1 usecs... upon failing to get the lock.

So process 4 transfers file_001.dat through to file_050.dat
into /ROOT/work.

/ROOT/work/file_001.dat
/ROOT/work/file_002.dat
/ROOT/work/file_003.dat
...
/ROOT/work/file_049.dat
/ROOT/work/file_050.dat

Then it releases the lock and begins processing meanwhile the other
processes wake up and try to grab the lock again... this time PID 2 gets
it. It does the same...

/ROOT/work/file_043.dat
/ROOT/work/file_044.dat
/ROOT/work/file_045.dat
...
/ROOT/work/file_049.dat
/ROOT/work/file_100.dat

/ROOT/queue/file_101.dat
/ROOT/queue/file_102.dat
/ROOT/queue/file_103.dat
...
/ROOT/queue/file_499.dat
/ROOT/queue/file_500.dat

Now while it was doing that PID 4 finished and all it's files are now
deleted. The first thing it does is try to get the lock so it can get
more... but it's still owned by PID 2 so PID 4 goes to sleep. Once PID 2
gets it's files it releases the lock and off it goes and the cycle
continued. Now there's still an issue with respect to incoming partially
written files. During the incoming process those should be written
elsewhere... lets say /ROOT/incoming. Once writing of the file is
complete it can be moved to /ROOT/queue. Also if you don't want
processes to delete the

RE: [PHP] file locking...

hi rob...

here's the issue in more detail..

i have multiple processes that are generated/created and run in a
simultaneous manner. each process wants to get XX number of files from the
same batch of files... assume i have a batch of 50,000 files. my issue is
how do i allow each of the processes to get their batch of unique files as
fast as possible. (the 50K number is an arbotrary number.. my project will
shrink/expand over time...

if i dump all the 50K files in the same dir, i can have a lock file that
would allow each process to sequentially read/write the lock file, and then
access the dir to get the XX files the process is needing. (each process is
just looking to get the next batch of files for processing. there's no
searching based on text in the name of the files. it's a kind of fifo queing
system) this approach could work, but it's basically sequential, and could
in theory get into race conditions regarding the lockfile.

i could also have the process that creates the files, throw the files in
some kind of multiple directory processes, where i split the 50K files into
separate dirs and somehow implement logic to allow the cient process to
fetch the files from the unique/separate dirs.. but this could get ugly.

so my issue is essentially how can i allow as close to simultaneous access
by client/child processes to a kind of FIFO of files...

whatever logic i create for this process, will also be used for the next
iteration of the project, where i get rid of the files.. and i use some sort
of database as the informational storage.

hopefully this provides a little more clarity.

[PHP] file locking...

[bruce]

Hi.

Got a bit of a question/issue that I'm trying to resolve. I'm asking this of
a few groups so bear with me.

I'm considering a situation where I have multiple processes running, and
each process is going to access a number of files in a dir. Each process
accesses a unique group of files, and then writes the group of files to
another dir. I can easily handle this by using a form of locking, where I
have the processes lock/read a file and only access the group of files in
the dir based on the  open/free status of the lockfile.

However, the issue with the approach is that it's somewhat synchronous. I'm
looking for something that might be more asynchronous/parallel, in that I'd
like to have multiple processes each access a unique group of files from the
given dir as fast as possible.

So.. Any thoughts/pointers/comments would be greatly appreciated. Any
pointers to academic research, etc.. would be useful.

[PHP] fork/spawnzombie question

[bruce]

Hi Nathan/Torok...

Hey guys... got a bit of a question.

I'm playing around with the php/for/pcntl_exec functions and I've got a process 
that spawns off a bunch of child processes. Unfortunately, I'm getting to where 
I have 100's of zombie child processes that I can see from the 
linux/processTBL. 

I don't want to have my master loop do a waitpid() call, as it would block on 
the wait for one of the child processes to exit. I recognize that the 
zombie/child process is essentially a placeholder in the processTBL slt, and 
really doesn't take up any system resources, but I'd still like to have the 
zombie processes removed. 

I'm wondering. Is it possible to fork off a process, and have it essentially do 
the wait on all the zombie/shild processes from the parent app? Or would this 
be a peer process, waiting on it's peers?


Thanks

i've got a project (goal) where i'm looking for a webbased app that
drives/runs/monitors different linux/system processes. i'm basically looking
for different apps that i can look at to get ideas/see their
layout/structure. i'm going to have to create a similar app to run some
processes that i'm dealing with.

i'm currently looking/searchin sourceforge.net/freshmeat/etc.. but i thought
i'd fire off the question here as well, in case someone has an app that
they're aware of that you can pass on to me..

my overall/ultimate goal is going to be to interface with underlying
database/tbls, to drive processes on a distributed network of machines that
i'm putting together... so i'm going to need to be able to to
monitor/start/stop a number of different apps that i create. i'm also
looking to be able to see past history of the apps that have been run using
the webapp...

but for now, any app that i can find that allows a user to manage/start/stop
different processes on a server/network would be useful.. (already looked at
nagios!)

How about

if I remember right
$match[0] would be all of it
$match[1] would be the numbers
$match[2] would be the text

Turns out I had a mistake in the test "client" ap/process that I was

It appears that the spawning/forking functions might work, but the child
apps would be in a zombie status, and couldn't be killed by an external

[bruce]

Hi...

Playing around with a test app to spawn external child processes.

I'd like to be able to spawn/fork/run am external child process, that:
 -allows the child processes to run as separate independent processes (pid)
 -allows the child process(es) to be terminated via cmdline (kill -9 pid)


i've got a dynamic situation, where i'm reading from an array, and for each
item in the array, i want to spawn/fork the child process. i'd like to be
able to have 10 copies of the spawned child process running at the same
time.

the only way i've been able to get my test working, is to spawn a group of
processes, and then to iterate through the group, using an array of pids,
and doing a wait for each pid in the array. however, this doesn't satisfy me
wanting to have a certain number of simultaneous processes running at the
same time..

thoughts/comments/pointers to articles that might demonstrate this would be
useful.

thanks...

i can easily post the sample chunk of code i'm playing with if someone wants
to look at it!

RE: [PHP] killing a child process from pcntl_exec

[bruce]

i'm pretty sure that's not the issue...

i should be able to spawn/fork any kind of external app/process... "kill -9
pid", especially if done as root, should terminate the process...

i suspect that the issue has to do with zombie processes, and how
php/pnctl_exec/etc.. operates.

There are functions/settings in pcntl docs about how to "listen" for
specific signals.

If you don't listen for -9, maybe you don't get it.

RE: [PHP] Re: killing a child process from pcntl_exec

[bruce]

hi carlos..

yeah.. the pid is correct.

it appears that spawning/creating a child process using pcntl_exec(foo)
results in a child process that you can see running from the cmdline, but
that you can't kill using "kill -9". php might allow some other function
within the parent app to allow the kill signal to be received by the child,
but i'm not familiar enough with php to know.

if i spawn the child process using something like "system()" then i can kill
the child, but i essentially have a bunch of parent processes running as
well. (ie, one parent process for each child process in the pid tbl)

what i really want, is the ability to spawn/create multiple external child
apps, each with their own child process ID, so I can kill it from the
cmdline. I'd also like to have a single parent processID in the pid tbl...

thoughts/comments/etc...

thanks

[PHP] killing a child process from pcntl_exec

[bruce]

Hi..

I fork a child process, using pcntl_exec. I see the process from the cmdline
(using pgrep 123), but I can't seem to kill the pid from the cmdline, using
"kill -9 123"..

Is there something that I need to implement within the php test in order for
the kill signal to be effective?

If I wait, the child eventually dies.. but I'd like to be able to kill it
from the cmdline.

thanks

[PHP] Looking for an app...

[bruce]

Hi List!


I know this is somewhat basic.. and I am searching google as I type! I'm
looking for a client/server app that allows me to have a quick/dirty client
that can upload/download a file to a server app, with the server app copying
the file to a given dir...

Code samples, or pointers to a site where I can download this would be
great!! I don't want a straight FTP, as I want to do more things with the
server piece...

And yes, a php/apache kind of app would be cool..

thanks!!

RE: [PHP] setting up FTP account names via PHP

[bruce]

are you moving the files from the ftpdir, to a separate dir?

if you are, you can run your cron process from the top level dir... get a
list of any underlying files, and then iterate through the list to copy the
files to whereever you need to copy them...

you'd use the 'ls -R...' or the 'find' cmd for what you're looking to
do...

Hello everybody,

thank you all for your help. I got a solution running. In pure-ftpd you
can authenticate via mysql. Via a user table, exactly the thing I was
searching for.

However, there is a problem araising. Every user get's his own directory
for uploads. My next step would have been to create a php script which
will be run by cron every 5 minutes that scans one dir and if there is
content inside import it into the mysql db.
With the current setup I would need to scan all dirs to see if there are
changes inside.

Is there some kind of command where I could find out if there are new
files inside those folders? I don't see any other solution.

Any suggestions?

Thank you for any help,

RE: [PHP] setting up FTP account names via PHP

[bruce]

merlin..

if you're going to allow a user to use the same user/passwd for the site,
and the FTP server.. i would strongly argue that you should allow the user
only the minimal access on the FTP server. if someone hacks your site, no
need to have them running rampant over your FTP server.

i would actually argue that you can have the same username, but separate
passwds, but i don'w know exactly what you're going to have on the FTP
server, nor do I know your skill at securing servers/services...

it doesn't really make a difference if you have separate dbs for the
user/passwd auth systems. if you secure the overall system, it's secure. if
you don't, well you're going to run into issues..

you might also look into existing web based mgmt apps for FTP servers to see
if any already exist.

Yes, it would be great if he could use the already existing username and
password. It should not be a one time password.

I am just now looking into mysql support for pure ftpd. One solution I
have in mind is to write the password into the pureftp DB upon signup.
That would be the easiest. The other solution to write to a conf file
would be OK, too. What do you think?

RE: [PHP] setting up FTP account names via PHP

[bruce]

are you trying to allow a user who logs in, to use his same username when
interfacing with the FTP server?

obviously, the password for the FTP server will be different. Or are you
looking to dynamically create a one time user/passwd for the user so that it
changes each time they access the FTP server?

[PHP] email app/script/needs...

[bruce]

HI...

Playing around with an app and I need to implement some functionality
allowing a user to email some text.

Basically, I want to allow the user to select some text from a dropdown
list. I then want to allow the user to edit the text if needed, and to then
submit the text for email to a given user. In order to perform some basic
QA, I want to have an additional user be notified of the email/text to be
sent, and to then have to authorize the email/text in order for it to be
sent.

The QA process is required as this is going to be part of a kind of stripped
down call center process.

I'm asking the list to see if anyone has come across this kind of
functionality in an app that you can point me to. I've been searching the
'net with no luck, and I'd rather not reinvent the wheel on this one..

Pointers/Comments appreciated!

Thanks!!!

[PHP] Need a brain to bounce some Mysql/DB thoughts off of!!

[bruce]

Hi guys.

Architecting an app that's going to have users interacting with different
levels of the db/tbls, and trying to figure out a few things.

The highlevel layout looks like:
 collegeTBL
 deptTBL

 with ->collegeTBL.id = deptTBL.colID

I also have a status tbl for each collegeTBL/deptTBL

 college_statusTBL
   userID
   collegeID

 dept_statusTBL
   userID
   deptID

 with:
  collegeTBL.id=college_statusTBL.collegeID
  deptTBL.id=dept_statusTBL.deptID

So I limk the statusTBLs to the college/dept TBLs...

This is due to the fact that a user can elect to work on either a college,
or a given dept of the college.

I'm struggling with a good/best way to figure out how to develop a query to
determine what level of a college, (if any) a user has elected to work with.

I can do a multiple join across the collegeTBL/deptTBL, and the statusTBLs,
but this simply gets a large tbl, and I'd have to then parse the results...
I'm trying to figure out if there's a better way, with a single query. The
query would look at the college(status), and then at the dept(status) to
determine what level (if any ) the user has selected.

I've got a mysql layout of the various tbls, and inserts if anyone's
interested in helping me shake my mind out on this...

thanks

my intended app will allow the user to select a given
 item (college, dept, course, faculty) and to store
 this data. when a user is displaying a list of
 items, i'd like to have my app determine if the
 child of the item has been selected by the user.

so. if a user has selected stanford, i'd like to
 be able to have a query that returns 'true' for
 any item, that has a 'child' (leaf) already selected by
 the user. (this should work for any level of
 childTBL)

so if a user has selected a course, from the 
 stanford, physics dept, physics 101, i'd like to 
 have a query that returns 'true' if the user 
 selects 'stanford' from the list of colleges...

i can't quite seem to figure out the sql to make it happen...

i'm hoping that this makes sense!!

Hello,

I have two tables one for category and other for category_hierarchy.

[PHP] Trre/Drop Down quick app for testing database tbls

[bruce]

Hi.

I've got a few tbls that I'm testing. I'd like to have a simple web app to
be able to iterate through the tbls to test out what I have in them.

I'd like to be able to have each tbl as a drop-down/select box, so I select
from selecta, which lists items from TBL-A, which then uses the id from
TBL-A, to get the items from TBL-B that matches. Selecting from drop-down
for TBL-B, then gets me the list on TBL-C...

I've got 3-4 tbls that are linked by their id.

Rather than reinvent the wheel, I'm asking if anyone has a quick app that
they can point to that I can extract/modify the functionality for my
needs...

Yes, I thought of that one too, but it's less flexible. What if you need
to add other fields to the college, or department. Then you'd need to
redo the whole structure to something more similar to what I did. Since
bruce was having issues, I gave him a flexible format that could handle
other fields if they arose.

Cheers,
Rob.

RE: [PHP] array/iteration issue!!

[bruce]

hey robert!!

thanks. and yeah, you're right, it's not the best.. so tell me, given that
i'm ripping through this on the fly, and i can have the structure in any way
i choose. this is just to simulate/populate some test tbls.. what's a better
way to create an array structure to have a collegename, followed by some
deptnames, followed by some classnames for the depts...

perhaps something like this??

$a = array
(
"college" => "foo",
array
(
"dept"  => "physics",
"class" => array
(
"class1" => "sss",
"class2" => "sffgg"
)
),
array
(
"dept"  => "english",
"class" => array
(
"class1" => "sss",
"class2" => "sffgg"
)
)
);

Your array is terribly structured. But the following provides traversal
in the way you want:

 "foo",
"dept1"   => array
(
"dept"  => "physics",
"class" => array
(
"class1" => "sss",
"class2" => "sffgg"
)
),
"dept2" => array
(
"dept"  => "english",
"class" => array
(
"class1" => "sss",
"class2" => "sffgg"
)
)
);

$college = $a['college'];
foreach( $a as $deptKey => $deptInfo )
{
if( strpos( $deptKey, 'dept' ) === 0 )
{
$dept = $deptInfo['dept'];
foreach( $deptInfo['class'] as $class )
{
echo "$college, $dept, $class\n";
}
}
}

?>

Cheers,
Rob.

You can't. You're array is valid but the second 'dept' key overwrites
the first. Thus the physics dept is lost.

Check it for yourself... print_r( $a )

RE: [PHP] Model Web Site

[bruce]

hi...

for what it's worth. the best approach might be to find a few sites that
have the functionality/layout you like. there are probably a few of them
that you'll run across that meet what you have in mind. use these as your
basic guides. add additional features that you'd like.

you now have (roughly speaking) the requirements/functions that you want
your final site to have. from here, you can figure out which "scripts" you
want to apply, and what you're still going to have to provide. keep in mind
that you can't simply throw scripts together, but you can use them to get a
sense of the underlying logic. you can also use them to see how to develop
your look/feel of your site.

looking at various scripts also gives you a chance to think about how you
want to implement your security/setup, as well as the underlying database
schema..

you can find plenty of apps/scripts on freshmeat.net/sourceforge.net as
well.

have fun!

My prime hobby is photography and the next is web site building.

So now I have a young model (18+) asking me about getting a web site.

The idea is members can see content, that will include, photos, her blog
and a discussion forum.

I like the idea of building it, but it includes a lot of things I have
no experience in.

Can someone point me to documentation/tutorials/scripts or anything that
might help.

I don't want a turnkey solution. I want to learn how to do this.

Thank you!

RE: [PHP] while-question

[bruce]

interesting points regarding college and programming..

my degrees bsee/msee covered alot more than pure programing.. as a double 
ee/cs, the ability to articulate an issue/problem, and bring to mind a cogent 
thought process was valuable. the ability to understand how different 
algorithms worked, and how code actually played with the lower intracacies of 
the processor where quite valuable. 

and no.. i'm no longer the engineer i was a time ago..

I don't "dabble" in it either, unless you consider making my living from being 
a dabbler, in which case I'll continue to dabble and see the pay for it.  My 
alma-mater tried to stay current to some degree, but when they let someone who 
wrote the C++ book try to teach it, well they gave that person more rope then 
they needed.

Tedd, glad you got hooked on Phonics.  One of these days I hope from graduating 
from just looking at the pictures, but right now the pictures are oh so 
enticing!. ;)

Not sure if it does what you want, but you might try looking at Google

He only said you couldn't use the + operator... nothing was said about

$total = -(-5 - 17);

Yes. How about get_included_files().

This of course shows the included files but if you *really* need to go much 
deeper (although this is probably an overkill) you could try tracing when the

[PHP] user access/roles/privs functionality

[bruce]

Hi list...

I need a way of managing users/teams/etc.. implementing roles/access
rights/privs,etc...

I'd like a way of being able to have users "report to" the resource above
them, ie, the ability to have a hierarchical kind of tree approach would be
good as wel, as this would allow different user/mgr/teams to be moved
up/down in the tree as required.

If I can find the right process, I'll implement it in my targeted app. I'd
prefer something that's fairly well compartmentalized.. but if need be, I'm
willing to rip the right system out of it's parent app if I can find one
that's good!!!

I've reviewed the systems in the vtiger/knowledgetree apps.

thoughts/comments/pointers would be useful!

RE: [PHP] PHP - Web/list Question...

[bruce]

hi T!!

This might work!

The items in my "list" are really scripts for given colleges, that have been
created by developers. This phase is a part of the workflow for the script
so the app can test the script, or run it in the production phase.

The testing portion involves testing the script, looking at the results, and
then either promoting the successful script to the production folder, or
returning the script back to the dev folder.

so, the testing portion is where i want to "group" the scripts. in reality,
i should look to test files either:
 -individual script (just want to run a quick test for a college)
 -by a user (might have made a few mistakes, so i want to test all his/her
scripts)
 -based on the date of completed dev (test all the scripts in the last 24hrs
that are in dev)
 -any other possible groups???

this process could work, as i could then simply have some checkboxes that
would interface with the mysql select to generate the list... i could then
allow the user to "delete" if nessasary from the list..

on the production side, since i'm going to crawl all the colleges to update
the data, i'd simply create/update a group that has all the colleges, which
can be automated, with no need for manual interaction...

this could work, and would eliminate the need for the pagination/session
approach..

if you have any other thoughts regarding possible selects/issues for the
testing/grouping process let me know your thoughts!!

thanks guys..

if one uses sessions, or a db store, the underlying logic to get the input
vars from the form on the individual pages (for the list) will essentially
be the same.

i'll have to have a form element, with the input items. i'll need to process
the checkboxes for each item, and when the user selects the
"continue/submit" btn, i'll perform the get/post action which then
accumulates the items from the previous page...

for each page, i'll have to process logic for the items listed in the form,
to see if the user has changed his/her mind... (ie, when the user goes back
to a previous page.)

when the user submits the "continue" btn, it'll present a list of the
selected items, allowing the user to revise the list, by going back to the
original lists (via the "back" btn) items can be deleted, via a delete
checkbox for each item in the list...

checking a "submit" btn will then write the final data to the db storage...


page 1,2,...:

  previous  - next
  state cityhospital   checkbox

  continue

the "continue" page

 -provides the list of the user selected items

  state cityhospital   checkbox

  revise - finish

on the "continue" page, the the user can "uncheck" the checkbox, to remove
an item, or the user can "add" additional items, by selecting the "revise"
btn, which goes back to the initial pages/list..

[PHP] PHP - Web/list Question...

[bruce]

Hi.

I've got a question/issue that I want to bounce off the list.

I have a list that extends over multiple pages. there might be 200 items,
and i don't want to have the items listed on the same page as it would be
too long. i can break the list up, so i can have it be displayed over
multiple pages. however, i want the user to select different items from the
list. given that the selected items might be over different pages, what's
the best way of keeping a running track of the items that have been
selected??

I could have each page be a form, and do a post/get where i then keep track
of the selected items from page to page, but that would appear to get ugly.
i'm looking for pointers to other sites/code that might have already
implemented this kind of scenario.

thoughts/pointers would be appreciated...


thanks

There can be no output before this (even whitespace before open php  
tags)

Is anything changing on the page?  If not, AJAX might be the way to go,
http://xajaxproject.org
Otherwise, pass the parameters you want to foo.php and have it redirect
to the proper page with the proper arguments.
Another alternative, is to store the parameters in the session and pass
them from foo.php without passing them to it.

[PHP] basic php question...

[bruce]

hi guys...

i've got a button that i want to select, and i want the app to process some
logic, and then return the user to the page. my question is how??

something like

base page:

button link"

foo.php
 -process logic
 -return the user to the base page, with the same querystring that 
  was initially used to generate the initial base page


foo.php doesn't have any display function, just the logic 

thoughts/sample php pages/psuedo code chunks...

thanks

RE: [PHP] Re: Simple app to Fill in TBL/Access Control Function.

[bruce]

Hi Maciek,

My bad for the confusion. A number of apps allow users to sign up, and
perform certain functions on the site, based on the user roles/access privs.
In some cases, the apps allow the user(s) to modify underlying data, that's
written to a given tbl. The ADMIN function for some of these apps allow the
admin user to disable/enable the user to perform certain functions, as well
as to change/modify the user access roles regarding the app.

I'm looking for an app that has the ADMIN function (user roles/access privs
built into it) that I can rip apart.

For my initial functionality, I'm looking to allow users to register/login,
be verified/validated by an ADMIN. The user will be able to create/modify
tbl entries. The user will also be able to modify the entries based upon the
roles/access privs assigned by the ADMIN.

I'm looking for pointers to basic apps that provide this kind of
functionality as a subset of the overall app. I can then rip apart/add what
I need to the app...

thanks

I have no idea what you want, that explenation is _so_ vague ("a TBL
(don't care what"... means... what exactly?). What exactly do you think
is "an ADMIN function" ?

Try to make it a bit more clear what you're looking for and we might be
able to help you. Your description is very confusing to me.
