[PHP] Question about template systems

[Matthew Croud]

Hello,

First post here, I'm in the process of learning PHP , I'm digesting a  
few books as we speak.
I'm working on a content heavy website that provides a lot of  
information, a template system would be great and so i've been looking  
at ways to create dynamic data with a static navigation system.


So far, using the require_once(); function seems to fit the bill in  
order to bring in the same header html file on each page.

I've also looked at Smartys template system.

I wondered how you folk would go about creating a template system ?

My second question might be me jumping the gun here, I haven't come  
across this part in my book but i'll ask about it anyway.  I often see  
websites that have a dynamic body and static header, and their web  
addresses end like this: "index.php?id=445" where 445 i presume is  
some file reference.
What is this called ?  It seems like the system i'm after but it  
doesn't appear in my book,  If anyone could let me know what this page  
id subject is called i can do some research on the subject.


Thanks for any help you can provide :)

Matt.

how else do you do it?

either it's open/anonymous, or some hardcoded account info. either
way, not very secure, and due to the nature of it, kinda requires the
user to have enough privileges to upload N files of X bytes (you could
put quotas on it, chroot it, blahblah... but still)

Smarty is a good choice, although some people might prefer other

http://www.php.net/manual/en/

The ID you mentioned is a query. "id=445&other_id=653" would be a  
querystring.
To retrieve data passed via this querystring you can use $_GET (http://de.php.net/manual/en/reserved.variables.get.php 
).

If you've looked at require_once() and it "fits the bill", then
chances are that Smarty might be overkill slightly.

> I wondered how you folk would go about creating a template system ?

I wouldn't (or at least, I wouldn't advise it). Use one that's already
out there and save your self some (a lot of) work.

I don't know of the specific name, but the URL is simply passing an
identifier (445) to the script (index.php). This ID could be the ID of
a record in a database, which is then retrieved and shown to the user.

Erm, don't know of the specific name, except that it's a GET parameter
(so I guess I do...). Everything following the question mark is
collectively known as the query string. You can retrieve these by
examining the $_GET variable. You will aalso find some useful things,
in $_SERVER.

[PHP] XML manipulation

[Raido]

Hi!

Manipulating XML files with PHP is quite new thing to me, so I could 
need a bit help with it.

Here are the questions(and below are XML schema):
1) Is it possible to change those blocks order?
For example I move  below 1.1.3 and it's number 
gets changed from 1.1.1 > 1.1.3 and  1.1.2 > 1.1.1 and 1.1.3 > 1.1.2
I also should be able to change order of blocks with number="1.1" (for 
example 1.1 > 1.8 and 1.8 > 1.1)  and number="1".


2) where and how should I approach?
Theoretically I think I should make a html list from the blocks and make 
it sortable with help of jQuery... beginning doesn't seem so 
difficult..but what happends then? (SimpleXML havent helped me with 
changing order..it helps me to change and read attributes.)



So any suggestions/ideas for completing that kind of solution are welcome.


And here is the XML (simplified)structure:

[PHP] Re: Fwrite() vs file_put_contents()

[RottenEye]

I Clancy,

Have you tried to convert your content to an .ini file? I heard that the 
php function "parse_ini_file" is very fast for reading this kind of 
files, although for writing you have to use some sort of php class, that 
can be slower than your method.

Depends what you trying to do I guess.

Regards


Clancy wrote:

I have been pondering whether it would be feasible to work with a 100,000 entry 
index
file, and had put yesterday aside to do some timing tests. I first generated 
some sample
index files of various lengths. Each entry consisted of a single line with the 
form

ASDF;rhubarb, rhubarb, 

where the ASDF is a randomly generated four character index, and the rest of 
the line is
filling, which varies slightly in length and contents from line to line, just 
in case
something tried to get smart and cache the line.  The average lenth of the line 
is about
80 bytes.

Then I wrote another program which read the file into an array, using the four 
character
index as the key, and the filling as the contents, sorted the array, and then 
rewrote it
to another file, reporting the elapsed time after each step.

My first version used fgets() to read the source file a line at a time, and 
fwrite() to
write the new file. This version performed quite consistently, and took 
approximately 1.3
seconds to read in a 100,000 entry 7.86Mb file, and another 5 seconds to write 
it out
again.

I then read the discussion following fschnittke's post "File write operation 
slows to a
crawl ... " and wondered if the suggestions made there would help.

First I used file() to read the entire file into memory, then processed each 
line into the
form required to set up my matrix. This gave a useful improvement for small 
files, halving
the time required to read and process a 10,000 entry 815 kB file, but for a 
30,000 entry
file it had dropped to about 15%, and it made little difference for a 300,000 
entry file.

Then I tried writing my whole array into a single horrendous string, and using
file_put_contents() to write out the whole string in one bang. I started 
testing on a
short file, and thought I was onto a good thing, as it halved the time to write 
out a
10,000 entry 800 K file. But as I increased the file size it began to fail 
dismally. With
a 30,000 entry file it was 20% slower, and at 100,000 entries it was three 
times slower.

On Shawn McKenzie's suggestion, I also tried replacing fgets() with 
stream_get_line(). As
I had anticipated any difference was well within below the timing noise level.

In conclusion, for short (1MB!) files, using file() to read the whole file into 
memory is
substantially better than using fgets() to read the file a line at a time, but 
the
advantage rapidly diminishes for longer files. Similarly  using 
file_put_contents() in
place of fwrite() to write it out again is better for short files (up to 
perhaps 1 MB) but
the performance deteriorates rapidly above this.

Re: [PHP] ldap_search filter with memberOf

[Romer Ventura]

If you notice when you get the "memberOf" back from the server you ll  
see it is an array with full CN; so if you dont want to loop through  
the array returned you can try to see if filtering with the full CN  
will work.


I found it easier to just get all of "memberOf" and then use PHP to  
get only the desired groups.

that the memberOf attribute has some internal structure that

What I have done is use a very broad $filter, an $attribs that  
includes "memberOf"-- and then loop through the results keeping  
only the students, thus:


$sr= ldap_search($ldapconn, $dn, $filter, $attribs);

for ($entryid=ldap_first_entry($ldapconn,$sr);$entryid!=false; 
$entryid=ldap_next_entry($ldapconn,$entryid)){


$this_memberof = implode(ldap_get_values($ldapconn, 
$entryid,'memberof'));


If (stripos($this_memberof,'student') ) {

// do something, etc.

}

But this is wildly inefficient. How can I just create the filter I  
need for ldap_search?

Here's a simple way of doing this: Set up a full page of HTML, with the
header, footer and all that stuff. But leave the center (content) part
of the page blank. You can call what you just built a "template". What
goes in the center could be called a "view". In the center of the page,
put a call like this:

include($view_page);

When you go to display the page, do this:

$view_page = 'apples.php';
include('template.php');

When the template page is included, it will, in turn, the view page
(apples.php) will get included. This works well if you want the same
basic look for all the pages of your site.

Just one way to do it.

Most likely, index.php is what is called a "front controller" (look it
up). The "id=445" is a GET variable being passed to index.php. The
index.php file checks this variable and decides which page to display.
It could be a page called "anything.php", but index.php knows that when
id = 445, it should display this page.

An awful lot of websites use a model-view-controller (MVC, look it up)
system using a front controller. There are tons of these about. My
personal recommendation for about the lightest weight of these is
CodeIgniter (codeigniter.com). Being lightweight also allows you to look
at its code and easily understand what it's doing and why.

[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.

Those are backticks. They execute a program via the shell. If you drop
to the shell and type whoami at the prompt you will get the same result.
The backticks operator returns the shell's output which is why it can be
echoed.

Those are called "backtick operators."  Like in BASh and most
other *NIX shells, that instructs the parser to evaluate, execute, and
return the result of the command within the ticks.

What you want to do with exec() is run it properly (RTFM for real ;-P).



The second parameter passed to exec() is the return array from
STDOUT, the third is the error response on channel 2 (STDERR).

I highly doubt that you're stupid you just need to pay closer
attention to what the manual is actually saying.  Check the user notes
as well, and then devise your own pattern from the collective examples
--- it'll jump-start your learning.

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...

text in back ticks is executed via a shell, text in single quotes isn't.

Depends on your keyboard - on my current keyboard, the back tick is sat
on the key to the left of '1' on the top row.

[PHP] possible session bug - Mantis Bug Tracker

[Edsall, William (WJ)]

Hello list!
 I'm having a strange problem with php after installing Mantis Bug
Tracker. I'm not sure if this is a Mantis bug or a PHP bug but I'm
leaning toward PHP.

 Here's what's going on. When I view an issue in Mantis, it is slow to
spit out the text and often does not finish spitting out the text on the
page. When it does this, the browser I was using is locked out from
further communication to the server. If I delete the session file in use
by this session, I am able to use the browser again immediately.
 
 I can't tell if this is a session bug or if Mantis is causing this bug.
Please advise!


PHP 5.2.4 with Suhosin-Patch 0.9.6.2 (cli) (built: Sep 22 2007 02:01:31)
Server version: Apache/2.2.4 (Unix)
Server built:   Mar  6 2008 02:37:06


Thank you ahead of time list.

Welcome to the Internet!

The first place you should look when you have a question is on
Google.  The first result that comes up for "backtick operator" is the
PHP manual itself:

http://php.net/language.operators.execution

If you don't know where a key is on your keyboard, please look down.

ok, ok, I found it but you guys are assuming that this is something

Single quotes don't interpolate (expand) variables within them. They are
for string literals. Only escaping recognized is \\ to include a
backslash and \' to include a single quote. Double quotes recognize all
sorts of escape chars such as \n for newline, \r for carriage return, \t
for tab, etc, etc. Additionally they expand embedded variables to their
value. Backtick key can usually be found to the left of the 1 key and
unders the escape key.

Cheers,
Rob.

You're assuming that we're assuming something (though I don't even
know to whom that's supposed to be directed).

Backtick operators have been around since the inception of UNIX
itself.  I don't mean this offensively by any means whatsoever, but if
you haven't run into them before, you haven't been tinkering very
much.

[PHP] Problems with displaying results

[Terion Miller]

I have two queries one pulls out which users to use and the second pulls
those users orders
Looks something like this but is only pulling the first record:


$query =  "SELECT `UserName`, `AdminID` FROM admin
  WHERE   Key1 =  'YES' ";

$result = mysql_query ($query) ;
$row = mysql_fetch_assoc($result);

//Reveal Variables for Debugging
// include("VariableReveal2.php");
 echo ("Hello ");
//echo $row['AdminID'];
echo ($row['UserName']);




if ($row['Key1'] == "NO") {
header ("Location: Welcome.php?AdminID=$AdminID&msg=Sorry, you do
not have access to that page.");
}

if (isset($_GET['SortBy'])) {$SortBy = $_GET['SortBy'];} else {$SortBy =
'WorkOrderID DESC';}
if (isset($_GET['Page'])) {$Page = $_GET['Page'];} else {$Page = 1;}

$PerPage = 30;
$StartPage = ($Page - 1) * $PerPage;

second query here is using the $row from the first (and yes I know
not to use *, just did so here to keep post shorter)

 $sql= "SELECT * FROM workorders WHERE AdminID =
'".$row['AdminID']."' ";
  // $sql .= "ORDER BY $SortBy LIMIT $StartPage, $PerPage";
  $result = mysql_query ($sql);
  $row2 = mysql_fetch_assoc($result);
  $Total = ceil(mysql_num_rows($result)/$PerPage);


So this works but only half way as it only displays the first record in
the table.

Hate to disappoint you, but on my computer (FreeBSD 7.0) on Firefox
Google does not go directly to the php manual... it goes to some nitwit
site thinkexist.com
So, this list is a much better source of information that waddling
through the crap that's thrown at you on G.
And I find that Googie is getting pretty garbagy even if there is
nothing better around ;-)
As for the keyboard, this is the first time I have ever, ever needed the
back quote key although I have occasionally needed the ~ key for Windows
stuff.

Others have shown how exec() returns the output.  If you use
shell_exec() it's the same as using the backticks:



-or-



You can use single quotes here also, i used double so you can easily
tell they are not backticks

The lock aspect is a feature. Otherwise one session might clobber
another session's data. PHP locks sessions so new ones won't begin
processing until the lock is released. This is why only one page can run
at a time. The code can release the lock early if it is finished with
the session, but whatever Mantis is spending time on, is before it
releases the lock (or finishes the page if it uses the default release
mechanism).

Cheers,
Rob.

Ok, but how does this relate to a command passed from a php Web page?
I don't understand the processus.
I use bash on my FreeBSD and have not needed a back quote yet that I can
recall... and on WinXP?

And I hate to disappoint you, but it's not related to the
operating system and browser being used --- it's a centralized remote
database in the form of a search engine.  The result you see with that
(unless you're using some particular language or locality preferences)
is the same I see, the same Per sees, the same Rob sees, the same we
all see.

I agree with you on that.  What used to be a superior algorithm is
slowly and inevitably turning into a standard, run-of-the-mill search
engine that's being SPAM'ed and exploited with blackhat SEO crap that
certainly lowers the value of the results as a whole.

Yeah, I think the only thing that Windows uses it for is
punctuation, but since ~1970 UNIX has used it for code execution
purposes.  Just keep in mind that, in PHP, it's run completely raw ---
so make sure you do your sanity checks before passing any kind of user
input to that (as always).

As in the email I just sent, remember to sanitize any commands
passed from the web (or anywhere, for that matter), but here are some
examples.



Single quotes means literal, double quotes means translatable, and
backticks means executable.

You need to lookup the mysql_fetch_assoc() function.  It only returns
one row from a result set that may contain multiple rows.  You need
something like:

while($row = mysql_fetch_assoc($result)) {
  // do something with $row
}

It's a matter of expectations. I am still trying to figure out why
anyone would want a GUI on any version of Unix or Linux. They just slow
me down and make it very difficult to do any real work.

You must be a point and clicker. Many, many, many people use the shell
to perform basic system administration, edit config files, even edit
source code. There are thousands of shell commands available at the
touch of your fingertips while in a shell. Using the backticks or exec()
function allows one to utilize these programs as part of a larger
program.

Cheers,
Rob.

Well, if you need to run any executable on the server to have it do
something or return something.  Whether you need to get some information
from the system or run an executable that does something specific.
Maybe you want to do a 'ps -ef' to get processes on linux, or maybe you
want to start a service on windows 'netstart SOMESERVICE'.

I'll try to digest all this today if not sooner... :-)
As to the sanitize, that is on my list of todos; I am not doing it as,
for the moment, I am only developing on my intranet server and do not
fear much external threats... anyway, "inch Allah" :-)
I appreciate the input and I take the chastizing with a ton of salt.

It's all in good fun and being the new guy, it's at your expense.  ;-P

Having thick skin means you'll stick around and probably learn a

Not really programming, more like overseeing the programming of others
(as a client) and trying to fix their awful mistakes about which I
learned from lists on the Net. I tinkered with some basic stuff and
looked into machine code back around `82... never very serious...
Now I'm trying to modify my daughter's ptahhotep.com to use MySql. It's
a learning experience.
My real profession if director and director of photography in motion
pictures and tv. :-D
I appreciate the help I'm getting here and the fact that I am tolerated

Ok, I thought I understood. The only programs I use that are non-shell
on FreeBSD are openoffice  and FireFox3, and sometimes Gimp. I use the
shell for administration of the server and program installation and
maintenance... I suppose a shell on Windows would be the cmd but I never
thought of it as a shell. :-)

Through the years I've probably sounded like a broken record or
like I'm paid to endorse them or something, but I'd recommend checking
out PHPBuilder for some of this.  Specifically:

http://phpbuilder.com/columns/index.php3?cat=1&subcat=2

Some other great sites for code snippets and examples are from
folks here on this list:

http://webbytedd.com/a.php
http://phpguru.org/

 and, of course, it should go without saying that Google and
the manual should be your first stop.

well I looked it up in my book and tried this example but still get the same

$result = mysql_query ($query) ;

I may not be gay, but I love my gay friends... and I do  not mean in the

Ah, to be a leader and represent the nation

Kennedy tells Germany that he's a pastry; Carter tells Poland that
he wants to be *very* friendly; Bush, Sr. offers his dinner back to
the folks of Japan; Dubya walks around holding hands a little too long
with the Saudi king.

We must look like the clown portion of the world circus sometimes

If you don't know the answer to that question, why would you ask the
original question? If you don't believe you don't have a use for this
material, don't worry about it. At the least, examine a book on the
subject, rather than asking questions here. If this was a
mission-critical part of your project and you need an immediate answer
now, then I understand asking the question here. But if the whole thing
is hypothetical, take the opportunity to read up on it; it's not
critical to your work at this point.

And asking us where a character is on your keyboard? Come on.

I'm the first guy in line to answer newbie questions if I can. And I've
castigated list members for framing their answers in a way which would
be impossible for newbies to understand. And I understand how things can
get confusing to newbies. But I sometimes reach a point where I begin to
wonder whether a newbie is actually paying attention. Or whether a
newbie is really just playing around, wasting our time because he won't
take the time to buy a book or carefully research an item on the web.

And FWIW, php.net has better documentation than that of any
other package I've ever seen. I keep a browser tab open to php.net at
all times.

[PHP] How important is your Express or Web Edition database? Please weigh in--

[Stan Stadelman]

Thank you to everyone who participated in the survey, or who posted to the
thread!

To cover some of the responses:

Yes, web-edition is a reduced-functionality version.  Typically they're
capped at 4GB, a la MSSQL Express Edition.

Our (Sybase) Web-Edition has no volume restriction, but access is limited to
web fronts.  The SQL Anywhere engineering team has solved the
offline/synching issue for local-store db's, such that you can run your php
locally, and provision/sync when connected.  It's likely that we'll deliver
this through the Web Edition, thus my queries.

Ash - I got the feedback, thanks!

[PHP] Cache engines in a multi-tenant environment (a bit long)

"multi-tenant" environment.  I've done some research on the open-source
cache engines available--specifically, APC, XCache, and
eAccelerator--but I haven't found anything that speaks to my use case.
Hopefully someone will be able to point me in the right direction.


Here's the basic use case:  I've got multiple instances of one PHP
application running on a single server.  This is accomplished in a
fairly straightforward manner:  We just create multiple copies of the
application on the filesystem.  It looks something like this:

/var/www/html/abc
/var/www/html/def
/var/www/html/ghi

Etc.


Each of the directories above ('abc', 'def', and 'ghi') contains a
complete copy of the PHP applicationwith slight variations based on
customer need.  Examples of these differences are LDAP parameters,
layout customizations, field names, etc.  Note that these variations
often occur in the PHP code, i.e. there will be multiple occurrences of
file "ldap.php" 


This works without incident but due to increasing adoption, performance
has become an issue.  In an attempt to improve performance, I
implemented APC.  This resulted in a significant performance gain, but
after several days we noticed intermittent problems that clearly
indicated one instance's code was being "leaked" to another instance.
As a specific example, we began seeing one customner's layout changes in
another instance.  These were quite obvious in that a field bearing the
wrong company name suddenly appeared.


After ruling out obvious filesystem mistakes I was forced to conclude
that the cache engine was serving the "wrong" version of a file.  I
enclose that in quotes because APC may technically doing the right
thing; given multiple copies of the same source file--as would
frequently occur in our environment--it cached the latest one and served
it up as requested.  However, this behavior is not compatible with our
hosting approach.


My question then becomes the following:  Is there a cache engine
available which can store multiple (different) copies of a source file
and serve them only to the appropriate request?  Perhaps a better way to
describe this would be a sort of "mapping" feature allowing
per-directory control.  I'm imagining a simple list of directories that
instructs the cache engine to keep their caches separate.  This might
even be implemented by incorporating the directory name into the key
used for lookups, but frankly I haven't spent much time looking at APC's
code (nor have I looked at XCache's or eAccelerator's at all.)


Thanks in advance for any guidance.



Regards,

Damon

If the path to the source file differs then it shouldn't matter that the
source tree is a copy, for all intents and purposes, as far as an
accelerator is concerned, the sources are different. I've not liked APC
in the past (I don't remember exactly what the problem was) and
personally use eAccelerator.

Rob.

[PHP] Re: Question about template systems

[Martin Zvarík]

Matthew Croud napsal(a):

Hello,

First post here, I'm in the process of learning PHP , I'm digesting a 
few books as we speak.
I'm working on a content heavy website that provides a lot of 
information, a template system would be great and so i've been looking 
at ways to create dynamic data with a static navigation system.


So far, using the require_once(); function seems to fit the bill in 
order to bring in the same header html file on each page.

I've also looked at Smartys template system.



If you are looking for performance stick to Blitz PHP - the only true 
template system.


Martin


Thanks for any help you can provide :)

Matt.

Are you sure this isn't just the default value before you attempted an
ini_set()? It may be that expect.timeout is not accessible at runtime.

Re: [PHP] Re: Can't set expect.timeout

[Clement Yui-Wah Lee]

Dear Rob,

The default value of expect.timeout is 10 (minutes), which 
is what I would get if I don't do any ini_set().  I could 
set the value to 0 but not to any values.


What do you mean by "inaccessible at runtime"?  I could set 
another  related parameter expect.logfile to, say, 
"/tmp/tmp" (as reported by phpinfo()).


This problem looks like a bug to me.  I will be most 
grateful if someone can try out the test program on their 
site.  Thanks in advance!

[PHP] Whats the correct syntax for using query results in a new query

[Terion Miller]

I'm trying to use the AdminID that returns from query #1 in the WHERE
AdminID = AdminID from Query 1

$sql= "SELECT WorkOrderID, CreatedDate, Location, WorkOrderName,
AdminID, FormName, Status, Notes, pod FROM `workorders` WHERE AdminID =
'".$row['AdminID']."' ";

that isn't working and the query 1 does return in this case 3 AdminID's so
I'm thinking it's just the .$row['AdminID'] part that is wrong
and I have tried some different things but am not sure the correct term for
what I'm trying to do so I can' t seem to google answers

Here is my query #1

  $query =  "SELECT `UserName`, `AdminID` FROM admin
  WHERE   Retail1 =  'YES' ";

$result = mysql_query ($query) ;
//$row = mysql_fetch_array($result);
while ($row = mysql_fetch_row($result)){

The way I've done it for a system at work (it is for staff and clients
only, so I guess that offers some protection) is to use scripts in
conjunction with vsftp. Accounts are managed through an admin web
interface, and each user has their own login credentials. Admittedly,
the username and password are passed as plain text for it to auto
log-in, but afaik, that happens with standard FTP anyway (unencrypted
connections). This is more than likely overkill for this situation, but
I had to resort to it as the system has to handle files over 2GB, and
file upload forms are just not meant to handle that kind of load in the
upstream!

For now, while you're learning about PHP, I'd use an existing template
system and tweak it to your needs. As you learn more, and need something
a little more bespoke, then you can look at making one yourself based on
what you've learnt about the coding and about existing template systems.
I've never used any myself, so I can't comment from first-hand
experience, but perhaps the Wikipedia entry may be of some help:

Are you using the latest release of Mantis? I've just installed 1.1.6 at
work (convincing people to use it is still an ongoing issue!) and it
works just fine. Do you have an odd settings in your php.ini?

Okay, I think I understand what you are trying to do.

//query 1
$query1 =  "SELECT UserName, AdminID FROM admin
 WHERE   Retail1 =  'YES'";

$result1 = mysql_query ($query1) ;
while ($row1 = mysql_fetch_row($result1)){

$admin_id = $row1['AdminID'];

//query 2
$query2= "SELECT WorkOrderID, CreatedDate, Location, WorkOrderName,
AdminID, FormName, Status, Notes, pod FROM workorders WHERE AdminID =
$admin_id";

$result2 = mysql_query ($query2) ;
$end_result = mysql_fetch_row($result2);
echo $end_result['WorkOrderID'];
echo $end_result['CreatedDate'];

}

This could be being handled any number of ways. 445 could refer to a row in
a database, a file on disk or a number of other things. All you really need
to know is that the script will take $_GET['id'], sanitise it (important!)
and use it as a resource identifier in a SQL query, filename or something
else. That will give the script the content to display. It would likely then
include a file containing the common header HTML, output the retrieved
content and then include a file containing the common footer HTML.

Even at the simplest level you'd probably call this an instance of the front
controller pattern (Google it), but they usually go a lot further than this.

As far as templating systems go I personally don't think they add anything
to the equation unless you're working with designers who are already
familiar with something. Separation of logic and content is important,
abstraction away from PHP is not (IMHO).

Rob,

Thanks very much for your response.  I was surprised at APC's behavior
(thinking that files in different directories would be treated as
different entities) but I couldn't explain the behavior I was seeing
otherwise.  However, that may be a function of APC specifically and not
all PHP cache engines.  I'll spend some time with eAccelerator and
hopefully it will work as expected.

Thanks again,

Damon

What about joining the queries?

SELECT admin.UserName, admin.AdminID, workorders.WorkOrderID,
workorders.CreateDate, workorders.Location, workorders.WorkOrderName,
workorders.FormName, workorders.STATUS, workorders.Notes, workorders.pod
FROM admin LEFT JOIN workorders ON (admin.AdminID = workorders.AdminID)
WHERE admin.Retail1 = 'yes'

I know it looks like a mess, but it should do the trick

incorrect syntax on your query

try

SQL query: SELECT WorkOrderID, CreatedDate, Location, WorkOrderName, AdminID
, FormName,
STATUS , Notes, pod
FROM `workorders`
WHERE AdminID in ( '20','61','24')

What happens if you just change your while loop to this:

while($row = mysql_fetch_array($result))
{
print_r($row);
}

[PHP] Intermittent problem sending mail with PHP

[Stephen Hutchison]

I've set up a small website which allows users to create a form letter and 
email it to their local candidates in the upcoming state election.


The user enters their email address, town/suburb and message into an html 
form and clicks the Send button. The site then sends an email to each 
candidate for their area. The email is plain text and only about 3k in size.


The problem I'm having is that it works fine for the first few tests but any 
messages after that it just hangs for 5 minutes before giving a time-out 
message. When it's working it goes through without any delay. If I leave for 
say anther half an hour its back working again. I send a couple more test 
messages its all good, but and then it hangs again.


How can I troubleshoot this intermittent problem? My ISP is running PHP on 
an IIS server. It seems like a server issue.


Thanks
Stephen

allow_url_fopen means you can fetch pages:

$page = file_get_contents('http://www.example.com');

This is ok to enable - all it does is fetch the page. It does
not execute the code it retrieved.


allow_url_include means you can remotely include code as if it
was on your server:

include('http://www.example.com/page.html'
);

That means if http://www.example.com/page.html includes any php
code, it will be executed on your server - this one definitely
is a security consideration.

If you enable allow_url_include be very careful about what you
include.

If you're still not sure, enable url_fopen, do not enable
url_include.

Hi Chris

Can i use curl option to php to take care of the security issue so that 
i can disable  both allow_url_fopen & allow_url_include in php.ini file.


allow_url_include is a security issue because it will actually execute 
the code returned from the url (like an 'include' or 'require' does 
locally).


allow_url_fopen is not a security issue - it only returns the code, it 
does not execute it.


But yes you can use curl instead of relying on allow_url_fopen.

[PHP] Re: Intermittent problem sending mail with PHP

[Stephen Hutchison]

This appears to by a problem with the mail function. When I comment out the 
lines:

if (mail($recipient, $subject, $message, $headers))
   echo 'Succeeded';
   else
   echo 'Error - please check your e-mail address';

and replace them with:
   echo $recipient . '';
   echo $subject . '';
   echo $message . '';
   echo $headers . '';
it displays to the screen perfectly every time.

Here's the output (ignore the hyperlinks, my news reader created those, in 
the browser they are plain text):

candid...@someparty.org

message subject

message body blah blah blah blah blah blah blah blah blah blah blah blah

More likely a mail server issue rather than the mail function itself.

Do they have any restrictions on how often you can send email? (Some 
hosts only let you send say 50 emails an hour).


Log everything you're trying to do in php (log when it works, when it 
doesn't) and include a timestamp - then get your host to look at their 
mail server logs for the failure times and see what shows up.

Well,  allow_url_fopen is really a security issue. A renowned programmer (
http://hasin.wordpress.com) said it could even cause DoS(Denial of Service)
for the running server.

Give the free eclipse a go. If you need an easy to use gui editor IBM
Websphere (which is also based on Eclipse):

Eclipse is great, has PDT (PHP Development Tools) too...

Re: [PHP] allow_url_fopen & allow_url_include

[Chris]

allow_url_fopen is not a security issue - it only returns the code,
it does not execute it.

But yes you can use curl instead of relying on allow_url_fopen.


Well,  allow_url_fopen is really a security issue. A renowned programmer 
(http://hasin.wordpress.com) said it could even cause DoS(Denial of 
Service) for the running server.


So can curl.

I realize this thread is old and dead and buried, but I have to get my

talk about how "~" was an alias for the current user context's home
directory in any POSIX system I've ever used. :)

Re: [PHP] Re: Intermittent problem sending mail with PHP

[Stephen Hutchison]

I'll check with my ISP but if is that then it's a very low limit. I'm 
finding it's only allowing two or three through before hanging.


Is there something i can put in my code so that it at least fails 
gracefully? It's not a good look just hanging like that.

More likely a mail server issue rather than the mail function itself.

Do they have any restrictions on how often you can send email? (Some hosts 
only let you send say 50 emails an hour).


Log everything you're trying to do in php (log when it works, when it 
doesn't) and include a timestamp - then get your host to look at their 
mail server logs for the failure times and see what shows up.

Yeah, I've been meaning to ask about that myself - what benefit is there
in using something like Smarty, which requires learning yet another set
of notation, over just having a class/interface for the page and calling
methods on that in plain-old PHP from the template?

--- the PHP page (e.g. index.php) ---



showPageTitle();?>
...
showCustomHeaders();?>


...
showMenu();?>
...
showContent();?>
...



--- snip 

For that matter, why go with Smarty over the more widely supported
(across multiple languages) XSL?

Maybe I'm missing something, but I don't see the point of special
templating systems that require you to know yet another notation set,
i.e. abstraction away from PHP as Stuart puts it.

In my 40 plus years of programming I don't think I have ever deliberately typed 
a back
tick, and had forgotten that it was on the keyboard. And I have tinkered with 
all sorts of
strange systems, but I have had very little to do with UNIX.

I have written a popular theme/template system for some CMS systems.  In
my opinion, templating is only needed for those that are totally
ignorant of the concept of programming languages in general.  It helps
for those designers that know HTML or they export their graphics as HTML
and know enough to modify it or add some simple tags like {post-date} to
HTML.  That's it!  No loops, no ifs, nothing.  Simple things
designers/users can add that represent some complex code, queries, etc...

PHP IS a template language.  You can easily separate your logic and
design/display using PHP.  Anything more than abstracting some complex
code to some simple var is overkill.  If you want to display a dropdown
of categories, and the code needed is a database query and some PHP
logic, etc., then it makes sense in my above scenario to do this in code
and then assign the result to a template var like {categories-dropdown}
that the designer/user can use in the HTML.  Other than that its just waste.

Smarty and similar template approaches just take PHP (but more limited)
and make it look slightly different.  Anyone who doesn't know or want to
know anything about programming will not see the difference between PHP
and Smarty.  Consider the following:

PHP: 

Smarty: {somevar}
//oh except in your PHP you have to do the following
//$smarty->assign('somevar', $somevar);
//$smarty->display('some.tpl');

PHP: include('header.tpl');

Smarty: {include file="header.tpl"}

Don't even get me started on loops and conditionals.  Smarty just
replicates PHP, except it looks slightly different and is much less
powerful.  If you are confused with:

if ($something) {
echo "Some stuff...";
} else {
echo "Some other stuff...";
}

Why is this better:

{if $something}
Some stuff...
{else}
Some other stuff...
{/if}

Like I said earlier, if you have some complex code that you can reduce
to a simple tag or something that a designer can insert into HTML then
great.  If not then it is just unsuccessfully trying to replicate PHP!

Actually, I forgot myself and the alternative syntax:

if($something):
echo "Some stuff...";
else:
echo "Some other stuff...";
endif;

Hardly different...

RE: [PHP] Re: Question about template systems

[Chetan Rane]

Hi

I think what you are looking for is static Header Footer and dynamic
content.
One way of doing this is by having the front controller pattern

For example : consider the following list of files in your application

1000.php
2000.php
1001.php
3000.php

In the front controller Pattern we usually have a only one file referenced
all eth time and most of the times it is Index.php

The code of your index.php file would be something like this

require_once "header.php";

require_once $_GET['r'].".php";

require_once "footer.php";

once this is done. To access any of the above mentioned files your URL will
be like this

index.php?r=1000 or index.php?r=2000 or index.php?r=1001 etc

The code given above is just the start point and is not secure enough and
had a Code injection threat. 
However I think this is enough to get you started.
You can do more research on what is Code Injection and how to avoid it.

Actually, I forgot myself and the alternative syntax:

if($something):
echo "Some stuff...";
else:
echo "Some other stuff...";
endif;

Hardly different...

Is there something i can put in my code so that it at least fails 
gracefully? It's not a good look just hanging like that.


Thanks

More likely a mail server issue rather than the mail function itself.

Do they have any restrictions on how often you can send email? (Some 
hosts only let you send say 50 emails an hour).


Log everything you're trying to do in php (log when it works, when it 
doesn't) and include a timestamp - then get your host to look at their 
mail server logs for the failure times and see what shows up.

I would recommend getting away from using the mail() function altogether.

I would look into using something like phpmailer or SwiftMailer.

They are SMTP mail classes that let you build and email and send it directly to 
your SMTP server.

Also allows you to log into the mail server with a valid email account and send 
using that account.

That last part might get you around the X/minute email limit or whatever else 
it might be.
