Greetings, Short premise before I get flamed: I know PHP 7 is rolling and it is way too late for this, that I should've tested the RCs, follow the mailing list and so on, but I'm a dev like you guys and struggle with the time to do everything by the book, including reading the previous threads because I'm pretty sure this was brought up by somebody, but as there are hundreds of message under the "Throwable" topic and I can't read all of them.
In short I have this situation: <?php class SpecificHandler { public function exception(Exception $e) { .. do something very useful... } } function global_handler($e) { SpecificHandler::exception($e); } set_exception_handler("global_handler"); ?> This happens because the specific handler will output the exception according to the expected format (HTML, JSON, or even an image). Now after upgrading to PHP7 when one of the new Error exception is thrown, I get the following error: PHP Fatal error: Uncaught TypeError: Argument 1 passed to SpecificHandler::exception() must be an instance of Exception, instance of Error given, called in [...] Having been a PHP dev for 10 years now I know that the policy is to try to break as little as possible while implementing new features, and I like that. I know that sometimes things must be broken to progress, but in this case maybe there is a very simple fix that I can suggest to avoid breaking existing code, change set_handler_exception like this: set_exception_handler(callback function, bool also_throwables = false); The new parameter "also_throwables" defaults to false, so the same behaviour as before is preserved. If you want it to catch also the new PHP7 Error exceptions, you can just set it to true. What is your take on this? I know I can easily fix my code to work on both PHP 5.x and PHP 7.x, but I really disliked this kind of BC. Kind regards Giovanni
