Remove parameters from url in PHP

In case you have a url and you want to remove all parameters from it use this:

$str = 'http://www.example.com/page.php?a=123&b=567';
$strClean = preg_replace ('/\?.+$/', '', $str);

1 2	$str = 'http://www.example.com/page.php?a=123&b=567'; $strClean = preg_replace ('/\?.+$/', '', $str);

This regex directive means – replace everything in the string coming after “?” with nothing.
