Dynamically invoking a constructor in PHP with variable number of arguments

I need to instantiate an object of a specific class type, but dynamically and with variable number of arguments. Essentially, I want a framework method that is similar to call_user_func_array() :

https://www.php.net/manual/en/function.call-user-func.php

But I want the arguments to be for a constructor, not a function.

So, instead of doing this:

$object = new MyClass(a, b, c);

...I want to be doing this:

$object = call_constructor_array('MyClass', array(a, b, c));

Is this possible?

What version of PHP? – Jonnix Jul 25 '19 at 10:58
@Jonnix It would be nice if it works on version 5.* (which I am mostly interested in), but if it is doable in later versions, feel free to reply. – user2173353 Jul 25 '19 at 11:00

5.6+ (as you'll see on the dupe) can be done with `new MyClass(...$yourArray)`. – Jonnix Jul 25 '19 at 11:03
Yep. I think that question is pretty much what I was looking for, just using terminology I would never use to ask the question... Thanks. :) – user2173353 Jul 25 '19 at 11:06
