Definitely unspecified behavior, at best an upgrading note can be added for this.

Sounds like undefined behavior to me. Is there documentation somewhere that says they'll be
returned in a certain order?

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
...
)
Url: https://3v4l.org/lEnsR
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.
