Edit report at https://bugs.php.net/bug.php?id=79350&edit=1 ID: 79350 Comment by: bugreports at gmail dot com Reported by: bugreports at gmail dot com Summary: 8.0-dev: Uncaught Error: Class 'PelEntry' not found Status: Analyzed Type: Bug Package: Scripting Engine problem Operating System: Linux PHP Version: master-Git-2020-03-07 (Git) Block user comment: N Private report: N New Comment: sounds like a terrible BC break and at least the error message is unhelpful nonsense given that even one of the zend engine experts pointed at include at the first try :-) Previous Comments: ------------------------------------------------------------------------ [2020-03-12 10:29:14] nikic@php.net Here's a reduced test case: <?php echo new Test, "\n"; class Test { public function __toString() { echo "Early bound!"; } } ------------------------------------------------------------------------ [2020-03-12 10:22:44] nikic@php.net No, that's not it. I think the issue is that this code is relying on early binding, and early-binding on the PelEntry class is now prevented due to implicit addition of Stringable interface. ------------------------------------------------------------------------ [2020-03-12 10:09:31] nikic@php.net I think something is going wrong with a recursive require_once. ------------------------------------------------------------------------ [2020-03-07 04:12:11] bugreports at gmail dot com Description: ------------ this is only broken with PHP 8.0-dev for some time now and it's technically not possible that a class defined in the include above the extending definition is not found require_once __DIR__ .
