Hi, I am looking for the most secure/efficient way to compare these two strings: /folder1/folder2/folder3/folder4/ /folder1/folder2/folder3/folder4/file.php Basically I am trying to setup as many security features as possible for a simplistic (home-grown/hand-coded) CMS... This appears to work: $haystack = '/folder1/folder2/folder3/folder4/someFileName.php'; $needle = '/folder1/folder2/folder3/folder4/'; if(substr_count($haystack, $needle) === 1) echo "yea"; Before making changes to "someFileName.php" I want to make sure it is within the allowed path ($needle). I would appreciate any advice. Even RTFM is cool. :D Many TIA, Cheers, Micky
