Submitted: 2003-12-19 06:22 UTC Modified: 2003-12-19 08:30 UTC
From: ovdspek at liacs dot nl Assigned:

PHP Version: 4CVS-2003-12-18 OS: win32 only
Private report: No CVE-ID:

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:

Actual result:
