Thanks, for your answer, I try to understand... but I use an internal
function of php that returns differents values depends of my processor
architecture ? It's correct ? Not should be the same and Php be in
charge of this and return alway the same value independently of the 32b
or 64b processor ?
Thanks, Bernardo.

(bogus means "Not a bug" here)
This is the internal representation of signed integer using unsigned
integer. 32bits use one bit for the sign, that explains the negative
_displayed_ values, but the internal values are the same.
Big numbers should be processed using bcmath or pecl/big_int

Hi,
I use this code in differents operating systems and plataforms (intel
and amd) and return differents results.
It's a bug ? Any comments ?
Thanks, Bernardo.
Reproduce code:

echo ip2long('255.255.255.192');
echo ip2long('255.255.255.248');
Expected result:
----------------
32 bits systems returns:
-128
-64
-8
---------------------
64 bits systems returns:
4294967168
