Delimiter must not be alphanumeric or backslash - preg_match

Posted: Mon Aug 04, 2014 4:56 pm

PHP Warning: preg_match(): Delimiter must not be alphanumeric or backslash in /home/**REMOVED**/public_html/admin/case/case.treasury.php on line 24.

Could someone please tell me what is wrong with the following line:

php Code:

if (!preg_match("/admin.php/", $_SERVER['PHP_SELF'])) { die ("Access Denied"); }

Hi Doulos, I haven't checked out the issue (though I suspect it's the / ), but I removed a key part of your root path, which could be used for malicious purposes.

Its simply a very old way to check if is it an admin-file. But there should be all fine. I can't reproduce this error in php5.3x. Maybe something before this line is wrong typed.

In RN25x you can go a easier way, so try this instead of your codeline to close it out:

php Code:

if (!defined('ADMIN_FILE')) {


	die('Access Denied');


}
