How about this...  Using a slightly modified array that you posted, I came up
with this in about 10 minutes

I am working with the following data structure

 array(
0 => array('Flight Number', 'flight_number'),
1 => array(
0 => array('Timestamp Departure', 'timestamp_departure'),
1 => array('Timestamp Arrival', 'timestamp_arrival'),
  )
),
  1 => array('Departure City', 'departure_city'),
  2 => array('Arrival City', 'arrival_city'),
);

print_r($in);

echo "\n\n";

$max_depth = 0;
$cur_depth = 0;
function max_array_depth($ar) {
global $cur_depth, $max_depth;
if ( is_array($ar) ) {
$cur_depth++;
if ( $cur_depth > $max_depth ) {
$max_depth = $cur_depth;
}
foreach ( $ar AS $row ) {
max_array_depth($row);
}
$cur_depth--;
}
}

max_array_depth($in);

echo "Max depth of array is: {$max_depth}";

?>

http://www.cmsws.com/examples/php/testscripts/dae...@daevid.com/0002.php


Globals are dirty for this kind of recursive utility function. Here's a 
cleaner example:

 $maxDepth )
{
$maxDepth = $subDepth;
}
}

return 1 + $maxDepth;
}

?>

Best way I can think of is to iterate the entire thing and keep a count
as you do. I'm not aware of any functions that can do what you need
there.

Using cron won't kill the server! Cron isn't only for scheduled tasks
but repeated ones as well and is perfect for running in the background
on a server all the time.

Indeed. This is kinda offtopic but if you put a cron running with a
loop you will kill your server. I would recomend use libevent + ALARM
signal to process on a time basis. On the other hand using C would be
a nice aproach since you can put your script on an sleep mode until
the next alarm signal is trigered + less resources taken

RE: [PHP] how to get the local time

2010-03-15 Thread Daevid Vincent

You either have to use JS on the client side. 

Or you store the user's timezone as a preference in their profile and
compute using that by setting a TZ variable.

Normally you would store all data in mySQL in UTC and then convert on the
fly as mentioned above for each user.

Might I ask, how are the multiple slashes getting generated in the first place?
 Where is the data coming from?

Next question would be: Do you want to completely remove all instances of
multiple backslashes?  Or, do you want to replace all instances of multiple
backslashes with a single backslash?

I would try something like this:

done!

What about this:

I think what was catching you out was that you were escaping the \
once for the regex, but then it needed it again because it was in a
single quoted string, meaning 3 slashes in total. Took me a little
while to figure that out as well!

The {2,} part just tells it to only remove the slashes where they
occur in runs of two or more.




I agree, it should work; but, it doesn't.

Most everything that looks reasonable works in The Regex Coach,

I'm starting to think there is a bug in the regex engine; haven't
looked yet.  It's doubtful though because the bug would screw existing

Thanks ever so much guys. Sometimes it's helpful when someone else confirms 
something must work.


Problem was that I had a series of cleanup and security checks on a POST array 
and inadvertently used the original POST array in one of the steps following the 
backslash remove step, so obviously it didn't work.

Do you mean local time as in the clients computer time? If so, as far as
I know you can't get that with PHP. What you would have to do is grab it
with JavaScript or something, and then pass that across to your server
script.

SOLVED.  As it turned out, it had nothing to do with ldap_bind() ... it had to 
do with the fact that my brain is still adjusting from the time change and I 
missed an 'echo' ...

No it's not. The short tags conflict with both XML and XHTML and
therefore are being phased out. You should be replacing them as quickly
as you can.

I would think that the PHP CLI extension would need to be installed on
the server for this to work. I don't know that that's common. (I could
be completely wrong.)

I would recommend coding this in C, because it would use far less
resources.

that's a documentation error.

it's not lazy, it's succinct and much easier to read (once you know what it 
means),
but ... if you require portable code and your liable to be running on shared
hosting where you don't control the ini settings you might consider not using 
it.

it is often feasable to turn them on explicitly in your 'init' routine so that
your template/output code can use short tags:



I can't recall that this is ever locked down on a server so that you can't
change it, although the default if quite often set to FALSE.

RE: [PHP] Event Handling

2010-03-15 Thread Alex Major

Thanks to all for your help on this, it's been very interesting for me to
read.

The system needs to check arrivals in real time (give or take a second or
two), using a cron job every minute doesn't provide the real time checking I
would like.

However, when I then got to thinking about it, wouldn't this be an ideal
solution? I create a PHP script that loops for 60 seconds, checking the
database each second for new entries and processing them (meaning I get near
real time monitoring), and then have that PHP script called by a cron job
every minute.

The reason I think that could be a good solution for me, is that if the PHP
script crashed (for any reason), then at most it's 59 seconds before the
system kicks in again and begins processing all the queued arrivals. If I
coded a PHP script to loop infinitely processing things every second, it's
possible I wouldn't notice a crash for a considerable amount of time. The
proposed solution provides a good fail-safe, I think.

Does that solution seem sensible? Or overkill?

Thanks again for your help in this, it's quite novel for me.

I agree. Even setting a cron on a local computer to call home to a

Dan;

The question wasn't whether or not it supports that kind of

mysqli_* stuff for years.  It's a known issue to us, but not to

Re: [PHP] long polling solution for LAMP with limited privilege

2010-03-15 Thread Rene Veerman

On shared hosting, you usually can't change the 30 sec max timeout on
the server..

So long polling >30s is not possible.

Short polling could be the answer, which can be done with ajax (see
jquery.com) from javascript, especially if you keep the cost of "are
there any new events for this client" down..

I believe this is the general idea. Various points within the area
(country, building, etc.) that you are mapping are the nodes within
the graph, so you are looking for the best (often, but not necessarily
the shortest) route between two nodes.

I'm not a regexp person (wish I was though), and I'm hoping someone can give

Essentially I have a sign-up form where folks will be typing in their
username.  The problem is, in our organization, when you tell someone to
enter their username, it could end up being any of the above examples
because they're used to a domain log in procedure where in some cases they
type the whole thing, in other cases just the e-mail, or sometimes just the
username.



So what I'd like is a way to capture just the 'username' part, regardless of
what other pieces they put in.  In the past I would write a rather
inefficient split() routine and eventually get what I need.  With split()
getting deprecated, I figured I may as well start looking into how to do it
properly.  There's preg_split(), str_split(), explode() . possibly others.



So, what's the proper way to do this?  How can I capture just the part I
need, regardless of how they typed it in?



Thanks!

The basic problem is that the slashes are legitimate characters for usernames 
per the RFC 5322; http://en.wikipedia.org/wiki/E-mail_address


However, per the "Notwithstanding the addresses permitted by these 
standards" paragraph, I disallow the "! # $ % * / ? ^ ` { | } ~" and have 
not found a problem.


You didn't mention whether you had control over the whole submission process. If 
so, I'd suggest checking the submitted address and sending back to the client a 
message asking them to correct their submission and resending it.


You can check for any of the above characters and bounce the submission back to 
the client.


Check out filter_var($emailAddr, FILTER_VALIDATE_EMAIL) It will catch a lot of 
errors.


Also, you'll find the helpful preg_match("%[[:alnum:][:punct:]]%", $addr); These 
are legit characters.  First remove everything following the @ and the @ itself. 
Obviously, you can use if(!preg_match) to catch anything not valid.


There are several str functions that'll do it or simply preg_replace("%...@.*%", 
'', $addr)

You could escape the content with strip_tags() and insert both copies
into the database if you're really worried about wasted resources. That
way, you keep a copy of the original data, and the one you're most
likely going to display in a web page.

It's like the whole argument about modifying textarea content to replace
newlines with  tags. At some point, you might need that content for
another use, and when you do, you'll wish you had the original. Just
because you don't see that use in your immediate future, it doesn't mean
it won't occur.

I used to think like that too, but I've relatively recently changed my
position.

While it's not as extreme an example, I used to keep data in the
database *after* I had processed it with htmlspecialchars() (not quite
the same as strip_tags, but the principle is the same).

The issue I had was that over time, I've found the need to output to
other formats - e.g. spread sheets, plain text emails, PDFs etc. in
which case this pre-encoded format is a pain and I have to call
html_entity_decode() to reverse the htmlspecialchars() I did in the
first place. This is a royal pain in the bum and it's really ugly in the
code, remembering what format the data is in in order to process it
appropriately at the right points.

Nowadays I work rather differently and always escape at the point of
output (this does not exclude filtering at the point of input too, but I
do not keep things encoded any longer - I keep it raw).

Any half way decently designed caching layer will prevent any major
impact from escaping at the point of output anyway.

Now you could argue that encoding at the save point and reversing the
encoding when needed is still a better approach and I wont argue too
heavily, but for the sake of my sanity I'm much happier working the way
I do now. The view layers are very clearly escaping everything that
needs escaping and no logic for the "is it or is it not already escaped"
leaks into this layer.

(I appreciate strip tags and htmlspecialchars are not the same and my
general usage may not apply to a pure striptags usage).

Indeed, it's more about XSS and CSRF rather than SQL injection.

the '&> /dev/null' redirects all output - I kind of make the assumption that the
script would be logging stuff to a file or something when in production.

so, yes, remove the redirection when your developing/testing the script.

Re: [PHP] Event Handling

+1..

Assuming you have had a 100% success rate of getting cars to their
destination on time for years;

If for some reason you can't set up a cron job, you _could_ have a
browser do the cron-ing for you; a page with an ajax script that kicks
off the check-for-recent-events script on the server.
granularity in milliseconds :)
if you have a windowing system on the server, you can run that browser
script on the server ;)

But if i were boss of such an operation, i'd have all cars outfitted
with gps, and have the gps monitoring app call up urls on my server to
indicate car status & location.
i agree this could be non-trivial, as something has to compare car
location gps coordinates to dropoff location coordinates, and if there
are many cars on the road, it's less than ideal to have the php server
do all the coordinate checking.
But there would be many benefits to a gps installation (with a "panic"
and "car-trouble" button in the vehicle).

RFID tags also might be a solution, one that could cost less to
install and operate.

I do believe removing the /dev/null will send error messages during the
building of the script, correct?

use cron - yes
have cron call a web URL - no, instead just call the script via the php CLI 
sapi,
e.g. a cmdline as follows in cron:

/usr/env php /path/to/your/check.php &> /dev/null

Re: [PHP] ldap_bind() connectivity

2010-03-15 Thread Peter Lind

You might want to check what the function outputs with:

var_dump($ldapbind);

after the call to ldap_bing(). That way you'll know what actually got
returned from the function.

ok so we have a script which checks if any cars have arrived within last 10
minutes... if yes, a mail will be send. suppose the server fails for 30
minutes so when the cron comes next time, we will have to check for cars
which arrived within last 40 minutes and not 10.. right...  so how will we
set a time limit in the script? its variable na.. but the flag is ok.. you
can send a mail to all db entries which have flag 0 and then update the flag

Consider a cron script that runs every 10 minutes. You'll want to check
the db for cars that are due to arrive within just over 10 minutes. The
flag is there more for you own clarification that the email has been
sent. What if the cron fails, or you restart your server, or the script
your cron calls is just running a little slowly?

hey ash,

do we need both of those checks ? ie the time and the flag? i think they
both do the same thing ie prevent duplicates.. am i right? and i think flag
would be a more reliable method coz it will ensure that the email will be
send even if the cron fails to execute for some time,

[PHP] ldap_bind() connectivity

2010-03-15 Thread Ashley M. Kirchner

Thanks to Jochem Mass for helping earlier to the string splitting.  Works
great (so far).  Now on to my next problem, which has to do with
ldap_bind().

 

I have the following code:

 

  $ldapconn = @ldap_connect($adServer);

  $ldapbind = ldap_bind($ldapconn, $ldapuser, $ldappass);

 

  if ($ldapbind) {

/** Successful authentication **/

$_SESSION['username'] = $username;

$_SESSION['password'] = $password;

  } else {

/** Authentication failure **/

$form->setError($field, "« Invalid username or password
»");

  }

  ldap_unbind($ldapconn);

 

The problem with this is that if the ldap_bind() fails in the second line,
it instantly spits text out to the browser:

 

Warning: ldap_bind() [function.ldap-bind
 ]: Unable to
bind to server: Invalid credentials in /home/contest/include/session.php on
line 351

 

And because it does that, it never reaches the if routine right below it and
everything just bombs.  If I call it with @ldap_bind($ldapconn .) nothing
happens.  The error message gets suppressed but it also doesn't do anything
with the if routine afterwards.  It's almost like $ldapbind isn't getting
set at all.

 

What am I missing here?

You could store the end times in the database, and cron can run a script
that will check each of these times to find any that are within x
minutes that an email hasn't been sent out for. You'll need an extra
field to indicate whether an email has been sent or not.

Re: [PHP] Event Handling

2010-03-15 Thread Midhun Girish

Hi ,
Just as David Hutto has said,What you need is the cronjob... Make a script
say "check.php" which checks the db to see if any new entries are made...
and if yes send the mail ...

now using the cronjob feature in linux os(which will be provided as a
service in your linux hosting cpanel), set a cronjob which calls the "
http://www.yoursite.com/check.php"; URL every minute now a trigger will
be there every minute to the script and the emails will be send irrespective
of whether anyone is browsing the site or not hope it is clear...

I'm a noob at php myself, but what you might want to look at is cron jobs
and autoresponders. Here's an address to one I've messed with before:
infinite.ibasics.biz/ I believe it uses cron jobs, I've messed with a lot so
it's hard to recall.

You might want to have the web app insert the new info in the tables, and
have the cron job and script do the rest.

I think what you want is something to trigger a php script every
$period-of-time; if your host supports it, cron is the means of executing
an application at regular intervals down to a minute granularity. There are
some web-based cron services also, but they may not have the same
granularity as a locally based cron.

[PHP] Event Handling

2010-03-15 Thread Alex Major

Greetings all,

I'm currently looking at building a web application, however I've run into
an area of development I've not come across before. The web site in its
basic form allows users to send cars from a point and then the car will
arrive at another point. When the car is set on its way, the start time,
travel duration and end time are all known and stored in a MySQL database,
what I would like to happen is that an event is triggered on the server at
the end time and then an e-mail is sent to the user. This should happen
regardless of whether someone is browsing the website or not.

I don't believe that I'll be able to solely use PHP, I have spent the
afternoon trying to look at potential solutions but I have to admit I've
drawn a blank. Google hasn't been helpful (64 pages so far), as any searches
related to "event handling" bring up a load of JavaScript tutorials/help for
'onclick' events etc. I have searched through the PHP documentation and
found "libevent" (http://www.php.net/manual/en/book.libevent.php ), I don't
believe that is what I require (although in all honesty the lack of
documentation on it means I'm quite in the dark as to its purpose). Another
potential candidate I came across was a PHP/Java bridge
(http://php-java-bridge.sourceforge.net/pjb/ ), whereby I could use the java
virtual machine, register events with it and then callback PHP scripts,
although this seems extremely long winded.

I was hoping that someone might have some experience with this kind of issue
and could point me in the right direction. I'm sure I've missed something
right in front of me. 

Alex.
