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?

thanks, so (int) is waaaaay faster apparently. Now I'm going to search and replace all my code — user824069, Jul 01 '11 at 01:02

(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 ] )

Yes, but is it the same? (as per the question title?) – Jared Farrish Jul 01 '11 at 00:55
@Jared Yes, unless the optional base parameter is something other than 10. – Jul 01 '11 at 00:59
@Jared "The same" is fairly ambiguous/subjective. – dkamins Jul 01 '11 at 01:19
@Jared Now I'm thinking you were just making fun of the question in the first place! – dkamins Jul 01 '11 at 01:21
@dkamins - No, I actually wanted the documentation in the answer to exactly answer the question, thinking of those who would come after and find this in a search. – Jared Farrish Jul 01 '11 at 01:23
