Hello,

I'm having a small problem with preg_match. Here's an html example:

<div class=headline>Black</div>


<B>Publisher</B><BR>
<A HREF="http://games.ign.com/objects/025/025025.html?ui=GameDetailBox">Electronic Arts</A><br>


<B>Developer</B><BR>

<A HREF="http://games.ign.com/objects/026/026357.html?ui=GameDetailBox">Criterion Games</A><br>

<B>Genre</B><BR>

First-Person


<A HREF="http://ps2.ign.com/genre_23.html?ui=GameDetailBox">Shooter</A>


<B>Release Date</B><BR>Winter 2005<br>

<B>ESRB Rating:</B> <A HREF="http://www.esrb.com/esrb.asp?ui=GameDetailBox" target="_new">RP</A><br>


This works: $title = preg_match("|<div class=headline>(.*?)</div>|",$buffer);

but this does not: $developer = preg_match("|<B>Developer</B><BR>(.*?)<br>|",$buffer);

I think it's because of the blank line between <B>Developer... and the <br> but I really wouldn't know, anyone who has an idea?

Thanks a lot!,
Cedric

hm another question.. Is is possible to only get the a-z, 0-9 characters from a phrase? for example.. I need "hello123" from "h:e ll . o 123" via preg_match or.. ?

Thanks,
Cedric

try this:

"#<B>Developer</B><BR>(.*?)<br>#s"

The s modifier causes the dot to match across lines. Also, I don't like using a meta character as a delimiter so I changed | to #, but that might just be me.

damn didn't work :(

This seems to work:



<?php

$str = "h:e ll . o 123";

$replacementStr = preg_replace('/[^a-zA-Z0-9]/', '', $str);

var_dump('$replacementStr', $replacementStr);

?>

It works for me:



<?php


$str = '<div class=headline>Black</div>


<B>Publisher</B><BR>
<A HREF="http://games.ign.com/objects/025/025025.html?ui=GameDetailBox">Electronic Arts</A><br>


<B>Developer</B><BR>

<A HREF="http://games.ign.com/objects/026/026357.html?ui=GameDetailBox">Criterion Games</A><br>

<B>Genre</B><BR>

First-Person


<A HREF="http://ps2.ign.com/genre_23.html?ui=GameDetailBox">Shooter</A>


<B>Release Date</B><BR>Winter 2005<br>

<B>ESRB Rating:</B> <A HREF="http://www.esrb.com/esrb.asp?ui=GameDetailBox" target="_new">RP</A><br>' ;


if (preg_match("#<B>Developer</B><BR>(.*?)<br>#s", $str) )
{
echo "it matches !!! \n";
}

?>



If I take the s modifier off it doesn't work.

damn, it's so weird... really doesn't work.. take a look at http://gamercentric.synchronized-1and1.com/zgrabber/3.php (3.php is the file mentioned above).. the releasedate, title work but not the developer :s (o yea.. you can see the page where the content comes from on http://gamercentric.synchronized-1and1.com/zgrabber/tempdir/gameinfo.html)

Sorry that I'm keep bothering you :blush:

The pattern in the first two here is wrong, you have (?) instead of (.*?).
Why are you doing preg_match three times?
What exactly are you trying to do with the matches?

--ed

nvm I found it, I placed all the content on one line, than it works

$filename = $tempdir."gameinfo.html";
$handle = fopen($filename, "r");
$buffer = fread($handle, filesize($filename));

$buffer = str_replace("\t", " ", $buffer);
$buffer = str_replace("\n", " ", $buffer);
$buffer = str_replace("\r", " ", $buffer);

what is the difference between (?) and (.*?) ?
