Description:
------------
It's currently possible to write a constructor that returns a value, but there is no way (as far as I can tell) to retrieve this value when constructing an object. Technically you can call the constructor directly, but this is not normally done in the course of object construction (other than calling the parent constructor).

While to experienced developers, the fact that you should/cannot return a value from a constructor seems obvious, this is not always so to newbies - https://old.reddit.com/r/webdev/comments/cf9l3h/working_php_code_working_on_a_test_server_isnt/

While thorough testing would obviously reveal this issue in the above case, we all know that not everyone, especially newbies, thoroughly test their code. In the above case the issue isn't obvious until an error in the curl query occurs, but all the user ends up with is an improperly constructed object - even if their code at the point of construction checks for a string value rather than an object, this check will never trigger.

Attempting to declare a return type already triggers an error: https://3v4l.org/rsikK

Test script:
---------------
<?php

class Foo
{
    
    public function __construct()
    {
        return "bar";
    }
}

$foo = new Foo();
var_dump($foo);

Expected result:
----------------
Error / warning that constructors cannot return a value

Actual result:
--------------
object(Foo)#1 (0) {
}
