Operating system: Windows NT 4 SP 6
PHP version: 4.3.4
PHP Bug Type: Unknown/Other Function
Bug description: ip2long("") = 0 intstead of -1
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
