Normally, you should use the preg_* family of regular expression matching. However, most of your ereg calls actually just search case insensitive. Instead of

!eregi("install", $_SERVER['PHP_SELF'])

use

stripos($_SERVER['PHP_SELF'], 'install') === false

. With preg_match, this would look like this:

!preg_match('/install/i', $_SERVER['PHP_SELF'])
