Bug #54195 [NEW]: The notorious "Call to a member function .. on a non-object" fatal error

From: Operating system: Irrelevant PHP version: 5.3.5 Package: Scripting Engine problem Bug Type: Bug Bug description:The notorious "Call to a member function .. on a non-object" fatal error Description: ------------ I had this problem a million times. It's very easy to accidentally invoke "Fatal Error: Call to a member function .. on a non-object". The problem is that this triggers an error so fatal that it can't even be caught by the shutdown function. This recently gave me a huge headache in a production system where an obscure bug where a variable contain null which was called on invoked a silent crash. It's a headache because I run everything in a framework with great wrappers for error handling/detection that are suppose to send me an email when obscure bugs get tripped. This obviously doesn't work when the PHP commits seppuku and explodes. I don't see any reason for this error to be that fatal. Sure, keep the error fatal but at least allow the shutdown function to catch it. Test script: --------------- \register_shutdown_function(function(){ $e = \error_get_last(); if (!\is_null($e)) die('Houston we have a problem: ' . \print_r($e, true)); }); $hello = null; $hello->bar(); Expected result: ---------------- Houston we have a problem: Array ( ...
