intval vs int

Involved Joined: Apr 06, 2008 Posts: 484

just wondering if there is a difference between the following 2 examples

Code:







$testy = inval($testy);





$testy = (int) $testy;

Is there any security issue's, or is it just pure prefence based.As (int) seems to be twice as fast.

I couldn't find anything on the php site about it

Slightly different output in various edge cases, but functionally they are pretty equivalent. I don't think there are security issues with either

I guess I will use (int) from now on then.

(int) directly type casts the variable and is SLIGHTLY faster in most applications. Books and such on optimization say to use that vs intval. Same with all other conversion functions.
