Description:
------------
Line 4 (09.0.0.0) fails in the following code.

Fails on both 4.3.4 and 5.0.0b2.

Haven't tried it in *nix.

Thanks,

Ross

Reproduce code:
---------------
<?php
ini_set('html_errors', false);
assert(ip2long('1.0.0.0') == ip2long('01.0.0.0'));
assert(ip2long('9.0.0.0') == ip2long('09.0.0.0'));
echo 'phpversion=',phpversion();
?>


Expected result:
----------------
Nothing.

Actual result:
--------------
$ php -q bug_ip2long.php 

Warning: assert(): Assertion failed in c:\ross\freebeer\www\demo\bug_ip2long.php on line 4

Unable to confirm.

Works locally on Win2K/SP4, Linux 2.4.22, and FreeBSD 5.1

Numbers starting with 0 are treated as octal; 09 is invalid octal.
[This is a feature of the socket libraries on most OS,
and is not PHP specific]

Solution: don't use numbers with leading 0's
