PHP - Force function parameter to integer

Question

In PHP you can do the following thing:

class Something {// bla bla}

function functionName(Something $object) {
    // Do stuff here  ^^^^^^^^^
}
         


        

Answer 1

You can't typehint scalar types in PHP. The only chance is to use a wrapper type. The SPL library ships with SplInt for that purpose.

Update: Looks like PHP 7 offers that feature. Sigh, times changed :)
