Description:
------------
ip2long returns 0 if the input is an empty string. However, an empty string is not valid, so it should return -1.

"The function ip2long() generates an IPv4 Internet network address from its Internet standard format (dotted string) representation. If ip_address is invalid than -1 is returned. Note that -1 does not evaluate as FALSE in PHP."

Reproduce code:
---------------
<?php echo ip2long(""); ?>

Expected result:
----------------
-1

Actual result:
--------------
0
