I'm sitting on a machine with en_US locale and this piece of PHP code

setlocale(LC_ALL,'de_DE.utf8');
var_dump((string)1.234);

returns

string(5) "1.234"

whereas on my colleague's machine which has a German locale, it returns

string(5) "1,234"

Why the heck does PHP use the locale when typecasting floats to strings? How can I disable it? I'd like to have this function return string(5) "1.234" on all machines, regardless of any locale settings.

Secondly and less important: Why does PHP ignore the setlocale on my machine?

it doesn't ignore the setlocale, you have to have the locale installed, (doesn't work in windows) check the return value of setlocale if its FALSE then you don't have the locale. – DevZer0 32 mins ago
@DevZer0.. a right, I guess it just isn't installed on my machine... – Treecj 27 mins ago
