robi_7 Posted May 27, 2011 Share Posted May 27, 2011 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.

Fadion Posted May 27, 2011 Share Posted May 27, 2011 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; ?> Quote Link to comment Share on other sites More sharing options...
