How hard should PHP try to finish a script?

Hi, PHP often throws fatal errors when it could throw an exception. Take PHP Fatal error: Non-abstract method foo::bar() must contain body this error for example. It would be possible to mark this class as 'invalid' instead and when doing a new foo , throw an exception. Or if you try really hard then only the method call should throw an exception. Or, I was extending ReflectionClass and got Fatal error: ReflectionClass::getFileName(): Internal error: Failed to retrieve the reflection object (same happens if you try serialzie / unserialzie on ReflectionClass as a comment in the manual points out). I could argue this is an exception and not a fatal. Let me quote documentation: Fatal run-time errors. These indicate errors that can not be recovered from, such as a memory allocation problem. Execution of the script is halted. I do not see the above or , indeed , most of fatals I see this sort of error. Sure, if a malloc call fails, the world has ended and it's time to die. Otherwise, could we just get an exception so that it can be handled ? Thanks Karoly "chx" Negyesi
