From manual page: http://www.php.net/function.posix-seteuid
---

The docs state posix_seteuid sets the real user id of the process. It does not. It sets the effective user id.

Test script:
---------------
		echo "	Setting UID to ".UID."\n";
		echo " USER ID ".posix_getuid()."\n";
		echo " USER ID ".posix_geteuid()."\n";
		if(posix_seteuid(UID)){
			echo "		Successfully set the UID\n";
		} else {
			echo "		Setting UID failed\n";
		}
		echo " USER ID ".posix_getuid()."\n";
		echo " USER ID ".posix_geteuid()."\n";
