Question

If I write a function like

function exd ($user = null) {
     return $user; 
}

If I call the function with no variable like

exd();

The value will be null?

But if I give the function a variable does the variable that I give become `$user`?

exd('account1');

Thanks couldn’t find it in the docs so thought I would ask here?!

Calling exd() returns null because $user is set to null as default value.If you use exd('account1') it’ll return account1. Because $user variable inside the function gets a value account1. Outside of the function you wont be able to get the value of $user.
