Description:
------------
After loading a class which inherits from other classes and parent classes are loaded by autoloader, get_declared_classes() gives another order than in previous PHP versions.

< 7.4: parent => child
7.4: child => parent

Result of code example (reverse order of get_declared_classes()):

Array
(
    [0] => A
    [1] => B
    ...
)

vs.

Array
(
    [0] => B
    [1] => A
    ...
)

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

spl_autoload_register(function($class){
    if ($class === 'A') {
        eval("class A { }");
    }
});

class B extends A {
    
}

print_r(array_reverse(get_declared_classes()));

Expected result:
----------------
Parent class(es) should be declared before child class.

Actual result:
--------------
Parent classes are declared before child class.
