note 65211 deleted from function.strstr by bjori

Note Submitter: thejasondean at yahoo dot com Reason: bad code ---- Also in response to: john :: beech :: at :: mkv25 :: dot :: net Trying to use your function to trim the last directory from a path i found out that it doesn't work if a directory has the same name as the subdirectory for example <? function backstr($haystack, $needle) { return substr($haystack, 0, strlen($haystack) - strlen(strstr($haystack,$needle))); } echo backstr('/var/www/site/test/test','/test'); // returns "/var/www/site" // instead of "/var/www/site/test" ?> My version for solving this 'special' problem : <? function back_dir($path){ $go1 = rtrim ($path , '/'); $back_dir = substr ($go1,0,strlen($go1) - strlen(strrchr($go1 , '/'))); return $back_dir . "/"; } ?>
