simple regular expression help

Recommended Posts

Hi Guys,

 

Need help writing a regular expression to match '&Itemid=457' (no quotes, there can by any value for Itemid) for further use in preg_replace() function. Actually need to find those items in html code and remove them.

It must be easy. I'm just not familiar with regex.

 

Any help would be appreciated.

Something as simple as this should work:

<?php
$s = '&Itemid=457';
if (preg_match('|&Itemid=(\d+)|', $s, $match)) {
echo $match[1];
}
?>

 

You could even use PHP's string manipulation functions. They're not as flexible and scalable as regex, but if the case is simple enough, they get the job done.

<?php
$s = '&Itemid=457';

$nr = substr($s, strrpos($s, 'Itemid=') + strlen('Itemid='));
echo $nr;
?>
