[PHP] ZEND_SET_SYMBOL compilation error
Hi, I am writing a PHP extension on Win32. I put a ZEND_SET_SYMBOL in the php_init_xxx_globals() and it failed to compile under Win32 using VC++ 5.0, the error I got: Y:\php-4.3.0\ext\wmcphp\wmcphp.c(138) : error C2065: 'tsrm_ls' : undeclared identifier Which corresponds to: ZEND_SET_SYMBOL(EG(active_symbol_table), wmc_sort_by_uid, uid); Any idea? It can be compiled under Linux without any problem.. Thanks! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Weird slowdown using complex functions in a loop
Hi, I'm trying to write a script to do some basic XML validation - nothing fancy, basically I just close open tags and check the arguments. The script runs fine, except that, when I use it in a loop (I need to validate roughly 200.000 posts), it gets progressively slower - like, the first ten calls to the function need around 0.01 seconds, next ten take 0.03, then it's 0.1 and so on. I've tried disabling parts of the code, I've tried profiling with dbg, I've tried manually optimizing: nothing. I managed to reduce the slowdown a bit, but it's still there, and very evident (as soon as I reach around a hundred posts, a single function call takes as long as 10 seconds). It may be interesting to note that I had to recode it from scratch: I wrote a class to do the same processing, and *that* ate memory like crazy, ending up with nearly 2 GB of used memory (according to XP taskman). If anybody has come across a similar problem, I'd love to know what did they do to solve it, but a suggestion on how to pinpoint the cause of the slowdown would be great as well. Uh, yes: I'm using PHP 4.2.2 and Apache 1.3.24 on an XP machine (but I've tried using PHP 4.3.0 and Apache 2, with the same results). pgcd -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Making a Loop.[Scanned]
Philip,
I might be missing something but just looking at the top few lines of your code the
$number variable has no value.
The loop will run on howver many times corresponds to this value - with the value
being null it's not going to run.
You'll need to pass in a value from elsewhere.

Where is $number assignment? Because $number is ZERO, your code will not

Re: [PHP] PHP Books
Hi Chris The first book, Teach Yourself PHP and MySQL in 24 Hrs: I got that one myself, but it tends to gather dust nowadays... It was very useful in the beginning with learning the basix syntax etc, but I quickly outgrew it, and rarely use it at all, not even for reference. I got the book called PHP and MySQL web development by Luke Welling and Laura Thompson. This is a great book, I sleep with it under my pillow and use it regularly as a reference to examples. I'd say it's basic enough to start out with, yet advanced enough to keep you interested as you grow more adept. BUT, I must admit, at this point, the single resource I use the most wrt PHP is the manual that comes with PHP, great reference to functions etc, but of course, you need to know of these functions before you can just refer to them... So, I would still suggest getting the Luke Welling et al book. There's a new edition on Amazon for $35, plus shipping of about $25. The last time I ordered, the Rand was much weaker, and the VAT was about R55, bringing my total to about R800, but it's well worth it... There is also a new book by Rasmus Lerdorf and it's cheaper than the book I mention, unfortunately I don't have insight into that book, and what would the guy that wrote PHP know about it anyway heh? ;p On Wed, 2003-03-12 at 11:45, Chris Blake wrote: Greetings learned PHP(eople), Can anyone offer comment on the following books on PHP.

[PHP] Threading objects
I want to be able to thread objects. I'm not really sure at all where to
start. but I want a script where multiple objects are being processed at the
same time.
I have an example php script
?
$a = new sleeper();
$b = new sleeper();
$c = new sleeper();
$a-sleepFor(10);
$b-sleepFor(5);
$c-sleepFor(1);
class sleeper {
function sleepFor($num) {
sleep($num);
echo sorry I was a sleep for $num \r\n;
}
}
?
I want so object $c would print then object $b then object $a as the
sleeping time is less and less.
Does that make sense? Please ask if you don't understand
Thanks for any help you can offer what so ever.

[PHP] two questions about usning session.
Hello, I have two questions about using sessions in PHP. Firstly, I use session to remeber the username and a session ID for the given user. When I hit the BACK button on the browser (IE), it always set that my page is expired and ask me to click the refresh button. How to prevent this from happening? Secondly, how is the PHP session ID be computed? When user A login, a session is started and his name nad session ID are stored. Now, on the same PC, I start another instance of the IE browser, login as User B, her name and session ID are stored under the same PHP session file. I switch back to the Windows of User A and continue to do something, the PHP session gives me the name of User B and User'B session ID. Why? Am I doing something wrong here?

Re: [PHP] Threading objects
i'm not sure what you want. But you have created objects here in $a,$b and
$c.
If you want to order them in a special way you have to write the
functionality of course. I think you have to do this before the object is
created because you define the variables 10,5,1 before the objects are
created. Once the objects are created they themselves don't know nothing
form each other. So th eparent object has to control this, or in your case a
'parent piece of script'.
You can use $a,$b,and $c as regular,ordinary variables. further on.
hope it helped,

Re: [PHP] Threading objects
Hi Wilbert
Thanks for responding. However I am completely aware of how objects work as
I come from a Java back ground.
If you are familiar with Java at all I'm looking for something like the
PipedOutputStream, PipedInputStream and Thread classes
I want the processes objects to be threaded, therefore processing
simultaneously.
This would mean $c would print first as it slept for the least amount of
time.
All I'm really asking is how do you initiate threading with PHP?
A small example would be nice
Regards
Kris

i'm not sure what you want. But you have created objects here in $a,$b and
$c.
If you want to order them in a special way you have to write the
functionality of course. I think you have to do this before the object is
created because you define the variables 10,5,1 before the objects are
created. Once the objects are created they themselves don't know nothing
form each other. So th eparent object has to control this, or in your case
a
'parent piece of script'.
You can use $a,$b,and $c as regular,ordinary variables. further on.

Re: [PHP] Threading objects
I think that he wants a function that acts like steTimeout(..) in
JavaScript ex:
code
setTimeout('alert('tst2')',5000);
setTimeout('alert('tst1')',4000);
/code
When you exec this code in js the first alert that is executed is tst1
and then tst2.
I don't know if you can do this in php without using threads.
I am not sure that this is the only function he whants to use this way,
but if I am not wrong threading dose the job very well.
btw what is the status of that project? Is it functional yet? I havent
read the php-dev discutions on this yet.

Hi,
generally, multithreading (using system threads) within PHP is
impossible, AFAIK. Of course running (apache) processes can communicate
via shm but it is not multithreading. Your code will be executed
sequentially as written. One sleep will start after another ends. There
is not known, to me, solution, sorry :(;

Hello,
I have two questions about using sessions in PHP.
Firstly, I use session to remeber the username and a session ID for the

that my page is expired and ask me to click the refresh button. How to
prevent this from happening?
That sounds like a problem with POSTed data from forms, not necessarily a
problem with sessions, or a problem a browser.
Have you got a URL we can play with?
Secondly, how is the PHP session ID be computed? When user A login, a
session is started and his name nad session ID are stored. Now, on the same
PC, I start another instance of the IE browser, login as User B, her name
and session ID are stored under the same PHP session file. I switch back to
the Windows of User A and continue to do something, the PHP session gives me
the name of User B and User'B session ID. Why? Am I doing something wrong
here?
Definitely.
- enable cookies on your browser
- make sure you're using PHP = 4.1
1. Start with a blank text file.
2. Copy and paste this in:

?php
session_start();
if (!isset($_SESSION['count'])) {
$_SESSION['count'];
}
else {
$_SESSION['count']++;
}
?
Hello visitor, you have seen this page ?php echo $_SESSION['count'] ?

To continue, A HREF=?php echo $_SERVER['PHP_SELF']; ?click here/A

3. Open it up in your browser, and test that it works (the value of
$_SESSION['count'] should increase with each click)
4. If that much works, open up the URL in a second window, and try to run
two separate sessions... (the first window might be on 10 clicks, and the
new one will be starting from 1)
5. If we're still cool, now try it without cookies maybe, by adding the SID
to the URL that they click on.
If all this works, then the problem is obviously in your code somewhere, not
an issue with PHP/sessions/browsers/cookies/etc.

Re: [PHP] Weird slowdown using complex functions in a loop

RE: [PHP] Hacker problem
Yes, theoretically...you could require it to be posted data. In order to do this you would have to make sure registered_globals is set to off in your php.ini and then for each variable posted from your form you will need to do something like this $name=$_POST[name]; This will only post the variables if they have been posted. Then you could use the referrer along with this and it will only allow data from that specific form. Hope this helps!

[PHP] Re: PHP Books
Don't know any of those but the books I have experience with so far (as a newbie with less than 2 weeks' PHP experience and next-to-no programming experience generally): 'Programming PHP' - Rasmus Lerdorf Kevin Tatroe (O'Reilly) - straight from the horse's mouth, as it were. Excellent book which quickly demystified sessions and security issues for me. Still grappling with the Objects chapter, but getting there. It's not a beginner's book to programming, but does a good job of explaining PHP. Highly recommended. 'PHP MySQL for Dummies' - Janet Valade - not a bad primer, but I very quickly outgrew it. Found I was working stuff out for myself before I got to the relevant chapters in the book. 'PHP Developer's Cookbook' - Sterling Hughes with contributions by Andrei Zmievski (Sams). Still playing with this one. Definitely not for beginners as it assumes (IMHO) a fairly well-developed familiarity with PHP concepts and procedures and general wirehead argot. But I get the feeling that I'll be turning to this one more and more as it is a resource of solutions to specific problems. About to delve into 'Web Database Applications with PHP MySQL' - Hugh Williams David Lane (O'Reilly), which I think is looking promising. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] two questions about usning session.
Hi Justin,
For the first problem, I found this option in PHP.INI do the trick:
; Set to {nocache,private,public,} to determine HTTP caching aspects
; or leave this empty to avoid sending anti-caching headers.
;session.cache_limiter = nocache
session.cache_limiter =
The default was set to nocache and after I change it to empty string, it
solved my problem.
For the second problem, I tried your script with two instances of IE 6.1
running, I didn't get two distinct values. Any idea?

prevent this from happening?
That sounds like a problem with POSTed data from forms, not necessarily a
problem with sessions, or a problem a browser.
Have you got a URL we can play with?
Secondly, how is the PHP session ID be computed? When user A login, a
session is started and his name nad session ID are stored. Now, on the
same
PC, I start another instance of the IE browser, login as User B, her
name
and session ID are stored under the same PHP session file. I switch back
to
the Windows of User A and continue to do something, the PHP session
gives me
the name of User B and User'B session ID. Why? Am I doing something
wrong
here?
Definitely.
- enable cookies on your browser
- make sure you're using PHP = 4.1
1. Start with a blank text file.
2. Copy and paste this in:
---
?php
session_start();
if (!isset($_SESSION['count'])) {
$_SESSION['count'];
}
else {
$_SESSION['count']++;
}
?
Hello visitor, you have seen this page ?php echo $_SESSION['count'] ?
times.p
To continue, A HREF=?php echo $_SERVER['PHP_SELF']; ?click here/A
---
3. Open it up in your browser, and test that it works (the value of
$_SESSION['count'] should increase with each click)
4. If that much works, open up the URL in a second window, and try to run
two separate sessions... (the first window might be on 10 clicks, and the
new one will be starting from 1)
5. If we're still cool, now try it without cookies maybe, by adding the
SID
to the URL that they click on.
If all this works, then the problem is obviously in your code somewhere,
not
an issue with PHP/sessions/browsers/cookies/etc.

RE: [PHP] Hacker problem
Well you can check the referer, but like someone else said, that can be faked, you can probably in Apache or somewhere disallow (if it's not by default) external post requests (ie from servers other then your own), and just make sure your using $_POST[message] instead of $message.

As I understand it, PHP sessions use cookies by default. If cookies are disabled, it switches to appending the session id to the URL. The advantage with using sessions is that all this is transparent to you and it therefore requires very little coding. Did you ensure the code below went into a plain text file? If you put it in an HTML page, it must come right at the start of the page, before HTML or any headers. Make it the first thing in the file.

Re: [PHP] two questions about usning session.
Session ID is stored in a cookie, and cookies are shared across
instances of browser: if you open another window of the same browser,
the same cookies are send, so you can have only one session to the same
site (and path). To prevent this, you would have to give up cookies and
use SID, but I don't know if it is worth the effort. If you just want to
test your session management, use other browsers at the same time -
mozilla, netscape, opera.

Hello,
I have two questions about using sessions in PHP.
Firstly, I use session to remeber the username and a session ID for the
given user. When I hit the BACK button on the browser (IE), it always
set
that my page is expired and ask me to click the refresh button. How to
prevent this from happening?
That sounds like a problem with POSTed data from forms, not necessarily a
problem with sessions, or a problem a browser.
Have you got a URL we can play with?
Secondly, how is the PHP session ID be computed? When user A login, a
session is started and his name nad session ID are stored. Now, on the
same
PC, I start another instance of the IE browser, login as User B, her
name
and session ID are stored under the same PHP session file. I switch back
to
the Windows of User A and continue to do something, the PHP session
gives me
the name of User B and User'B session ID. Why? Am I doing something
wrong
here?
Definitely.
- enable cookies on your browser
- make sure you're using PHP = 4.1
1. Start with a blank text file.
2. Copy and paste this in:
---
?php
session_start();
if (!isset($_SESSION['count'])) {
$_SESSION['count'];
}
else {
$_SESSION['count']++;
}
?
Hello visitor, you have seen this page ?php echo $_SESSION['count'] ?
times.p
To continue, A HREF=?php echo $_SERVER['PHP_SELF']; ?click here/A
---
3. Open it up in your browser, and test that it works (the value of
$_SESSION['count'] should increase with each click)
4. If that much works, open up the URL in a second window, and try to run
two separate sessions... (the first window might be on 10 clicks, and the
new one will be starting from 1)
5. If we're still cool, now try it without cookies maybe, by adding the
SID
to the URL that they click on.
If all this works, then the problem is obviously in your code somewhere,
not
an issue with PHP/sessions/browsers/cookies/etc.

Sorry for the delay in responding to your posting, I have been grappling
with your suggestion for a while and still things are not working out.
I have included all my code below and seek your advice..
As it stands, the resultant HTML page prints out the content of each
file, but it puts it all in the right table row, as opposed to splitting
it up for each row(file).also, my code, when viewed in vim, is all
in blue after inserting the $result string you gave me.
By taking out the * at the end of your statement, it reverts back to
showing things in the proper colours, but the page is blank with the
exception of the table formatting
I have tried a lot of different things with your code but am now ready
to start kicking the cat out of frustration.

[PHP] Long script execution and its implications?
Hello, I hope this question isn't too vague. I am opening a large csv file (up to 30,000 lines), splitting it out into its elements and then making several INSERT, SELECT queries on my DB. It's a hack and not very elegant (but as a beginner i will try to work on it in the coming weeks) This process is taking a really long time and I get about 5 or 6 thousand lines in and php times out (5 minutes). Now I could set the max_execution_time to a higher level but in the back of my mind i think there might be a more correct way to make all these selects and inserts. Like breaking it up into smaller chunks or something. My question is multifaceted. a) i can't echo any status information to the screen while the script is executing (because of course it hasn't finished yet). But is there a way to do this (something like line 3..line 4 etc of csv)? b) is there a better way (conceptually) to process such a large file with each line having up to 5 separate queries on my db. c) what would be the implications of raising the memory limit (i am running apache/php/mysql on windows xp locally on my laptop) d) should i just increase max_execution and live with the blank screen for 8 minutes (i'm basically trying to crunch data for later reporting) Any info, direction to documentation welcome (i did look but as a beginner I find its hard to know where to start.)

[PHP] PDF - PHP (on the fly using templates??)
Hi,
BACKGROUND
I am looking to create a series of Certificates and Brouchures etc and then
using the products Print/Acrobat Distiller option save the documents as
PDF(with some pre-built in Name1, address1, address2 variables
that can be automatically resolved
on-the fly using a PHP script using a PDF_REPACE(see below code) option or
something similar. This then allows me to Create Nice looking
Brouchures/Certificates etc with variable abc markers before
converting to PDF so my online user can have personalised stationary
without the need for them to EDIT any of the documents.
My attempts using PHP - PDF on the fly
===
I am looking for guidance on whats the best method and am I on the right
track without using the long winded PDFLIB functions..
I wonder if you could help(I'm going round in circles!), I a looking to use
PHP - PDF, probably with PDF templates instead of actual PDFLIB coding
techniques.
I have tried to create a simply script(before I move on)which will process a
PDF pre-written template and resolve variables on the fly(without using
any PDFLIB functions etc). I created a simple script to do this using
Microsoft RTF but obviously this would only work on PC's where users have
WORD etc...(I assume)
I have tried myself but keep getting the error msg The file is damaged and
could not be repaired when it trys to load the amended PDF file(see the
sample script below).
By the way, the script works fine if I comment out the PDF_REPLACE option. I
assume these are causing some type of error?? I tried updating the Acrobat
prefences/options to not load in a Browser but that just downloaded to my PC
and the same error message appeared after I double clicked on it...
The PDF template small script is attached as an example.

Re: [PHP] Encrypting/Compiling PHP Scripts
There is also Source Guardian. If you need a program that will support an unencrypted configuration file, ie, user definable variables, this one will do it.

Re: [PHP] Weird slowdown using complex functions in a loop
Actually, the concept is the following: - split the text into a number of elements (tags and text between tags) and put them into an array - fix each element (text and tags) to prevent attributes and entities from breaking the parser - check all the elements to make sure that they are either self-closing (text or empty tags) or matched by a closing tag somewhere - append sequentially the text from all the elements to $result - empty the elements array - return $result I honestly don't see how this can lead to a slowdown... - Original Message - From: Jimmy Brake [EMAIL PROTECTED] To: pgcd [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Wednesday, March 12, 2003 2:16 PM Subject: Re: [PHP] Weird slowdown using complex functions in a loop where are you storing the information that you are cleaning once it is cleaned? are you appending it to a variable in the script? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Query string inconsistency
Hi -
I have a PHP msg board on one domain, and a site on another, the idea is
that the board is framed. The PHP msg board pages detect whether they're in
the frameset, and if not, pass their URL query string over to the
frameset. The frameset then grabs this and writes a frame src tag, thus
enclosing any msg board page within the right frameset even if opened
outside it.
The problem is that the $QUERY_STRING is inconsistent. On it's own domain, a
test page works fine. But when the test page uses the framing mechanism, the
$QUERY_STRING only picks up the first argument - it ignores any subsequent
ones. I've got these two variations here:
http://www.alleykat.co.uk/t1.php?arg1=rg2=bbbarg3=ccc
This one works fine and grags all the args. It doesn't try to send to the
frameset.
http://www.alleykat.co.uk/t2.php?arg1=rg2=bbbarg3=ccc
This one sends to the frameset, and gets only the first argument.
The code in these pages is below. The only difference in the two is that the
javascript line is uncommented in t2.php, so it sends to the frameset:-
?php
$thisURL = $REQUEST_URI ;
$thisPage = $PHP_SELF;
// Try a few ways of grabbing the query string
$qs = $QUERY_STRING;
$qqs = $_SERVER[QUERY_STRING];
$qqqs = $HTTP_SERVER_VARS['QUERY_STRING'];
$gotoURL = http://www.alleykat.co.uk; . $thisPage . $qs;
?
script language=Javascript type=text/javascript!--
// uncomment line below to send to frameset
//if (top.frames.length == 0) { window.location.href =
http://www.virtualmagrep.com/vmr_forums.asp?u=?php print($gotoURL);?; }
//--
/script
?php
print($thisPage) . - php_self br;
print($qs) . - query_string br;
print($qqs) . - second query_string br;
print($qqqs) . - third query_string brhr;
print($gotoURL) . - the built url br;
print(hr);
phpinfo();
?
Not sure if this is a bug or if I'm doing something wrong.

[PHP] google, php-created pages and link farm exclusion
dear list, 1) Currently Google cannot find all pages on my site because most pages are linked through database-generated selection boxes. Most pages have URL's with different query strings after index.php. 2) I have made shortcut links possible such as mydomain.org/page/37 and mydomain.org/person/jones. 3) I considered making a database-created page, maybe called links.php, with a list of all currently active pages, straight html links. But will that work? I heard that Google has a policy to block so-called 'link farms'; pages cramped with links, aimed to increase page ranking. Would that exclusion also be used when the links are only for my own site? My most important goal is that if someone looks for [Jones soil research], they do see a link to the page of Jones. Ranking is not that important.

[PHP] Force refresh of graphic - how?
I have a PHP page which in turn calls an image-creating PHP program, like so: ...(calling page: mypage.php).. body IMG SRC=makepic.php?opt1=abcopt2=def /body /html makepic.php does database lookups using the values of opt1 and opt2, then creates a graphic (PNG) using that data and returns the graphic. So far, so good... but the graphic is being cached, so the data is not always up-to-date, unless I do a shift-reload of the calling page. I tried adding a pragma nocache line to the HEAD of mypage.php, but that had no effect.

Definitely.
- enable cookies on your browser
- make sure you're using PHP = 4.1
1. Start with a blank text file.
2. Copy and paste this in:
---
?php
session_start();
if (!isset($_SESSION['count'])) {
$_SESSION['count'];
}
else {
$_SESSION['count']++;
}
?
Hello visitor, you have seen this page ?php echo $_SESSION['count'] ?
times.p
To continue, A HREF=?php echo $_SERVER['PHP_SELF']; ?click here/A
---
3. Open it up in your browser, and test that it works (the value of
$_SESSION['count'] should increase with each click)
4. If that much works, open up the URL in a second window, and try to run
two separate sessions... (the first window might be on 10 clicks, and the
new one will be starting from 1)
5. If we're still cool, now try it without cookies maybe, by adding the SID
to the URL that they click on.
If all this works, then the problem is obviously in your code somewhere, not
an issue with PHP/sessions/browsers/cookies/etc.

More info on the meta tag: http://www.xs4all.nl/~dimaroan/htl/index.html -- Ray On Wed, 2003-03-12 at 09:49, Mark Wilson wrote: I have a PHP page which in turn calls an image-creating PHP program, like so: ...(calling page: mypage.php).. body IMG SRC=makepic.php?opt1=abcopt2=def /body /html makepic.php does database lookups using the values of opt1 and opt2, then creates a graphic (PNG) using that data and returns the graphic. So far, so good... but the graphic is being cached, so the data is not always up-to-date, unless I do a shift-reload of the calling page. I tried adding a pragma nocache line to the HEAD of mypage.php, but that had no effect. I don't want to tell my users to always do a shift-reload - how can I force either mypage.php to not cache the graphic, or get makepic.php's output to not be cached Thanks... replies to [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I am looking for learning more about sessions... I´m test this code below
don´t work with me My php version is 4.1.2.
Anybody have a complete example code of how use sessions?
Another doubt: Sessions use cookies? What the advantage in use sessions
instead of cookies?

Definitely.
- enable cookies on your browser
- make sure you're using PHP = 4.1
1. Start with a blank text file.
2. Copy and paste this in:
---
?php
session_start();
if (!isset($_SESSION['count'])) {
$_SESSION['count'];
}
else {
$_SESSION['count']++;
}
?
Hello visitor, you have seen this page ?php echo $_SESSION['count'] ?
times.p
To continue, A HREF=?php echo $_SERVER['PHP_SELF']; ?click here/A
---
3. Open it up in your browser, and test that it works (the value of
$_SESSION['count'] should increase with each click)
4. If that much works, open up the URL in a second window, and try to run
two separate sessions... (the first window might be on 10 clicks, and the
new one will be starting from 1)
5. If we're still cool, now try it without cookies maybe, by adding the SID
to the URL that they click on.
If all this works, then the problem is obviously in your code somewhere, not
an issue with PHP/sessions/browsers/cookies/etc.

[PHP] Parsing help needed, regular expression perhaps?
I am grabbing this page and trying to grab the stats on the page:
http://slam.canoe.ca/StatsHKN/BC-HKN-STAT-TORONTOSTAX-R.html
The code I had worked just fine before but now that there are players that have
multiple lines, it's not working as I'd like it to. Below is the code that worked and
I need help to get it to ignore the lines of players from other teams and just get
thheir total number.
$statsURL = http://slam.canoe.ca/StatsHKN/BC-HKN-STAT-TORONTOSTAX-R.html;;
$season = 2002-03R;
$urlHandle = fopen($statsURL, r);
if (!$urlHandle) {
echo $errstr ($errno)br\n;
exit;
}
$rawHtml = fread($urlHandle,100);
fclose($urlHandle);
$rawHtml = stristr($rawHtml, pre);
$stats = substr($rawHtml, 0, strpos($rawHtml, /pre)-1);
$playerline = preg_split(/\n/, $stats, -1, PREG_SPLIT_NO_EMPTY);
$count = count($playerline);
echo Players: $countP;
for ($x = 0; $x = $count; $x++) {
$playerstats = preg_split(/[ ]/, $playerline[$x], -1, PREG_SPLIT_NO_EMPTY);
}
