Bug #79474 [Fbk->Nab]: get_declared_classes Wrong loading order Inheritance

Edit report at https://bugs.php.net/bug.php?id=79474&edit=1 ID: 79474 Updated by: nikic@php.net Reported by: ahwelp at universo dot univates dot br Summary: get_declared_classes Wrong loading order Inheritance -Status: Feedback +Status: Not a bug Type: Bug Package: Class/Object related Operating System: Linux PHP Version: 7.4.4 Block user comment: N Private report: N New Comment: Order of get_declared_classes() is unspecified. PHP 7.4, just like previous PHP versions, returns classes in order of registration. PHP 7.4, unlike previous PHP versions, can register a class before its parents, if that was the order in which the classes were loaded. Previous Comments: ------------------------------------------------------------------------ [2020-04-14 16:29:37] requinix@php.net Is there anything in the official documentation that says they're returned in a particular order? Besides a user comment from 15 years ago? ------------------------------------------------------------------------ [2020-04-14 11:50:26] ahwelp at universo dot univates dot br Description: ------------ The function get_declared_classes() should return the loaded classes in the order they were defined. When a PSR-4 package is required and one class is extended on the local code, the child class is registered before the parent. In PHP7.3 the parent is registered before the child. In PHP7.4x the child is registered before the parent Test script: --------------- #composer require jasonlewis/menu dev-master #Small package, good for testing <?php include 'vendor/autoload.php'; use JasonLewis\Menu\HtmlBuilder; class BootstrapBuilder extends HtmlBuilder{} var_dump(print_r(get_declared_classes(), true)); Expected result: ---------------- Execution on PHP 7.3 string(4086) "Array ( [0] => stdClass [1] => Exception [2] => ErrorException [3] => Error .....
