PHP: How to Pass child class __construct() arguments to parent::__construct()?

Question

I have a class in PHP like so:

class ParentClass {
    function __construct($arg) {
        // Initialize a/some variable(s) based on $arg
    }
}
         


        

Answer 1

This can be done in PHP >= 5.6 without call_user_func_array() by using the ... (splat) operator:

public function __construct()
{
    parent::__construct(...func_get_args());
}
