Question

Possible Duplicates:
Fastest way to convert string to integer in PHP
PHP: Is there any particular difference between intval and (int)?

Is (int)$var same as intval($var) ?

Apparently they both do the same thing.

Is there any situation in which they would return different results?

Answer 1

(int) would seem to be a bit faster than intval, as you don’t have the overhead of a function call. intval also allows you to set an optional base to convert to, which might be useful:

int intval ( mixed $var [, int $base = 10 ] )
