[PHP] Using Variable Variables from form values inside a function

[Ron Dyck]

Is it possible to use variable variables from form values inside a function.

For example when submitting form values,  this works fine:

foreach($_POST as $key=>$value) {

    if (empty($$key)) {
        print "empty value $key<br>";
    }

}

but, this doesn't:

function myFunction() {
 foreach($_POST as $key=>$value) {

     if (empty($$key)) {
         print "empty value $key<br>";
     }

 }
}

Anyone dealt with this?
