Req #78351 [NEW]: Possible to check for invalid class

From: php at braten dot be Operating system: Irrelevant PHP version: Next Minor Version Package: Scripting Engine problem Bug Type: Feature/Change Request Bug description:Possible to check for invalid class Description: ------------ It should be possible in PHP to check if a class exists or has a certain method without throwing a fatal error if the class is invalid. This has become an issue since https://bugs.php.net/bug.php?id=76980 was fixed, and is described in more detail in https://github.com/symfony/symfony/issues/32395 This is a feature request for the next version of PHP to allow functions like get_class_methods, get_class_vars, get_parent_class, is_a, is_subclass_of, class_exists, class_implements, class_parents, trait_exists, defined, interface_exists, method_exists, property_exists, is_callable to be called without throwing a *fatal* error if a class or interface does not exist. It can be ok if you later do "new" on the same class, that PHP must throw a fatal error. But it should be possible to get a negative result from the above mentioned functions without a fatal error.
