Someone gave me the preg_match equivalent preg_match( '/([-_a-z]+)\.([a-z]+)$/i', $row['site'], $match2 ); I tried that and it took care of the problem, as far as I can tell. To me, that narrows it down to a problem (bug?) with ereg... anyone else have any ideas? ---John Holmes... > -----Original Message----- > From: John Holmes [mailto:holmes072000@charter.net] > Sent: Tuesday, April 23, 2002 6:01 PM > To: php-general@lists.php.net > Subject: [PHP] ereg() not matching same text each time script is run... > > Okay...I'm really at a loss for this... > > (PHP 4.0.6 on Redhat Linux) > > I've written a little script that shows the top referrers for > http://www.falkware.com.
