preg_match_all

[megafu]

hi i need some help with this regular expression stuff.

 

 

i want to get the userID . but i cant manage to get the regular the right way .

 

thanks for any help 

 

here is the code i have:

//<a class="" href="/user/userID" onMouseover="irrelevantstuff" onMouseout="irrelevantstuff">


function getInfo($var) { 
$preg = '*href="/user/*+"*';
preg_match_all(trim($preg), $var, $out);
$keys = $out[1];

if ($keys == NULL)
   {
     die('No Match Found!');
   }

  return $keys[0];
}

Based on what you've given--the href attribute always uses double quotes--the code below will work. It needs tweaking if you want to match single quotes or no quotes at all.

 

<pre>
<?php
$string = <<<STR
	<a class="" href="/user/bob" onMouseover="irrelevantstuff" onMouseout="irrelevantstuff">
	<a class="" href="/user/suzy1" onMouseover="irrelevantstuff" onMouseout="irrelevantstuff">
STR;
preg_match_all('%(?<=href="/user/)[^"]+%', $string, $matches);
print_r($matches);
?>
</pre>
