I agree that that should be the same. But sadly, Windows uses a different integer size model than almost everything else modern. Where Linux and Mac and other unices use 8 bytes for an "int", Windows uses 4 bytes (http://en.wikipedia.org/wiki/LP64#Specific_C-language_data_models). Because PHP internally uses "int" for its integer type, on Windows that's still only 32 bit. But yes, it would be awesome if PHP actually took care of this and uses 64 bit ints on 64 bit processors. > Also, telling developers that "an integer always > supports 64 bit" will make life much easier for them when they need it for > implementing large numbers in cryptography, date arithmetics, scientific > values, API interaction, etc etc. PHP's DateTime classes do use 64 bit integers internally, no matter on which processor (even 32bit ones). cheers, Derick -- http://derickrethans.nl | http://xdebug.org Like Xdebug?
