PHP default function argument as a T_VARIABLE?

Question

I\'m trying to provide a member variable as a default value for a class method.

I know it\'s impossible to use a variable as a default value for a non-class function

Answer 1

I believe you can only use constants (strings, numbers, etc) in that syntax (but I could be wrong about that).

I suggest this alternative:

function getTest($var = null) {
    if (is_null($var)) {
        $var = $this->test;
    }
}
