Bug description: ip2long('255.255.255.255') should return 4294967295 on 64-bit
PHP
Description:
------------
On 64-bit platforms, ip2long() returns a positive result for IP addresses
>= 128.0.0.0. This is expected.
However, there is *one* case in which it will return a negative result:
when the specified address is 255.255.255.255.
This inconsistency doesn't make sense. Yes, the documentation does say
that ip2long() returns -1 for 255.255.255.255, but that should only be the
case on 32-bit platforms, where all addresses >= 128.0.0.0 return a
negative result.
Reproduce code:
---------------
echo "ip2long('255.255.255.254') = ", ip2long('255.255.255.254'), "\n";
echo "ip2long('255.255.255.255') = ", ip2long('255.255.255.255'), "\n";
Expected result:
----------------
ip2long('255.255.255.254') = 4294967294
ip2long('255.255.255.255') = 4294967295
Actual result:
--------------
ip2long('255.255.255.254') = 4294967294
ip2long('255.255.255.255') = -1
