Need help with preg_match

Hello, i'v looked it up on php.net but was a little confused, so I gotta ask around

Say I had a text file containing a code such as

<b>texttexttexttext</b><i123>[B]clay[/B]</i><br><u>ping</u>

Code (markup):

I want to get the data between the <i123> and </i> tags, excluding the <i123> and </i>, and store it in a variable called $data, so when I put the code:

echo "$data"; 

Code (markup):

the text clay will be displayed.

Thanks!

 

Well I put this together real quick, it doesnt use preg_match, but you can try it and give it a go:

<?php
$page=file_get_contents("file.htm"); // change to correct file name
eregi("<i123>(.*)</i>", $page, $result);
$data=$result[1];
echo $data;
?> 

PHP:

 

One problem, when I try to get the content from a page from another site (i'm using a myspace url) it grabs all of the content of the myspace page and puts it into the variable too. Any suggestions?

Edit: Fixed it, thank you, smatts9!

 

<?php
preg_match('#<i123>([a-z0-9-]+)</i>#si', $contents, $data);
echo $data[1];
?>

PHP:

 

<?
$string = '<b>texttexttexttext</b><i123>clay</i><br><u>ping</u>';

preg_match('/<i123>([^<]*)<\/i>/', $string, $match);

echo $match[1];

//or 

$data = $match[1];

echo $data;
?>

PHP:

 

Note that a-z0-9- can be simplified by \w. (Only thing, \w includes underscores as well.)

 

Thanks nico_swd, didn't know that
