[PHP] Making sure a variable is an integer

Chronicle · 14 Feb 2006 at 16:01

I know its just a simple function, can't remember or find what it is.

Need to make sure that for example ...

PHP:

$id = $_GET['id']

is always ONLY an integer. I've done it but it requires 3 if statements, i'm know i had a (built in) function that worked a while ago but can't remember it.

Thanks

Is there a way to just convert any string/floating point number, into just an integer?

ie, something like $id = MakeItIntoAnInt($_GET['id']) ?

Thanks

Thanks for your replies.

This is something I've never worked out with PHP... In Java or whatever, you always define if something is for example a string, int etc. How do you do this sort of thing in PHP?

When i set $example = "1", would that, like that, be a string? Or an integer?

Thanks
