Re: Why do disabled functions / classes generate a WARNING.

I don't see how it is any more recoverable than the function/class not existing at all. How much code do you know of that checks for the existence of every function it expects to be there, before using it? The matter is even worse with classes, since creating a disabled class does not return null. It returns an instantiated object with no methods. When an unexpected function is disabled, the engine can recover, sure. The code, probably not. In my opinion it's better to stop the code doing something potentially harmful than allowing it to continue with bad data. It seems inconsistent to me. -- $a = new UndefinedClass; // PHP Fatal error: Class 'UndefinedClass' not found -- $a = new DisabledClass; // Warning var_dump(get_class($a)); // string(13) "disabledclass" -- $a = undefinedFunction(); // PHP Fatal error: Call to undefined function undefinedFunction() -- $a = disabledFunction(); // Warning var_dump($a); // null
