Question

A and B have function with the same signature — let’s assume : foo($arg) — and that class A extends B.

Now I have an instance:

$a = new A();

$a.foo($data);

Can I also run the parent’s (B’s) foo() function through $a or was it overridden?

Thanks!

It is overridden but if you want to use both you can do this:

function parentFoo($arg)
{
    return parent::foo($arg);
}

If you want that the child function calls the parent function do this:

function foo($arg)
{
    $result = parent::foo($arg);
    // Do whatever you want
}
