Description:
------------
---
From manual page: http://www.php.net/function.ip2long#refsect1-function.ip2long-examples
---


Test script:
---------------
<?php
$ip = long2ip(ip2long("10.0.0")); // "0.0.0.0"
$ip = long2ip(ip2long("10.0.256")); // "0.0.0.0"
?>

consult to the documentation of these two example. the two line of codes will return valid IP address. but in fact, in PHP 5.3.2, it return 0.0.0.0.

<?php
echo ip2long('127.0.256'); //return 0.0.0.0
echo ip2long('127.0.255.0');//return 0.0.0.0
?>



Expected result:
----------------
refer to the documentation: 

<?php
$ip = long2ip(ip2long("10.0.0")); // "10.0.0.0"
$ip = long2ip(ip2long("10.0.256")); // "10.0.1.0"
?>



it will return 10.0.0.0 and 10.0.1.0 in my environment, but it's not, it returned 0.0.0.0. the documentation said that the parameter required a standard format address. parameters in example are not standard format address, and it's return value is not correct. 

This snippet of example should be correct.

Actual result:
--------------
<?php
$ip = long2ip(ip2long("10.0.0")); // "10.0.0.0"
$ip = long2ip(ip2long("10.0.256")); // "10.0.1.0"
?>

actual result is 0.0.0.0
