Question

How would i go about writing a function that would handle the data in an array?

What i mean is, can i use

function CheckStuff($_POST){}

instead of

function CheckStuff($_POST['var1'], $_POST['var2']){}

Reason im asking is i need the function to work through all the values stored in the array and there are quite a few.

Answer 1

Sure.

function CheckStuff($arr) {
    foreach($arr as $key => $val) {
        //...
    }
}
