What about 02.123.123.123? that should be in octal still 2 right? it returns
false.
<?php
$aIpAddresses = array("2.123.123.123", "102.123.123.123",
"202.123.123.123");
foreach ($aIpAddresses as $sIpAddress)
{
echo "Ip: ",$sIpAddress,PHP_EOL,"<br />",
"Long: ",var_export(ip2long($sIpAddress),
true),PHP_EOL,"<br />";
$aIpAddress = explode(".", $sIpAddress);
$aIpAddress[0] = substr($aIpAddress[0], -2);
$sIpAddress = implode(".", $aIpAddress);
echo "Ip no int: ",var_export(ip2long($sIpAddress),
true),PHP_EOL,"<br />";
$aIpAddress[0] = (int) $aIpAddress[0];
$sIpAddress = implode(".", $aIpAddress);
echo "Ip int: ",var_export(ip2long($sIpAddress),
true),PHP_EOL,PHP_EOL,"<br /><br />";
}

That is expected.
"All numbers supplied as parts in IPv4 dotted decimal notation may be decimal,
octal, or hexadecimal, as specified in the ISO C standard (that is, a leading
0x or 0X implies hexadecimal; otherwise, a leading '0' implies octal;
otherwise, the number is interpreted as decimal)."

Description:
------------
IP2Long does not handle leading zeroes
Reproduce code:
---------------
<?PHP
echo LONG2IP(IP2LONG('192.068.068.068'));
?>
OR
<?PHP
echo IP2LONG('192.068.068.068');
echo '<br>';
echo IP2LONG('192.68.68.68');
?>
Expected result:
----------------
Notice the top example should return back the same IP. The bottom example,
should produce the same LONG number.
