Re: How hard should PHP try to finish a script?

Hi, I think the example of the abstract method not containing a body is a bad example, as it is fatal and would normally be caught at compilation in a compiled language. I think these sorts of errors shouldn't be catchable, although, I can see instances where it could be a useful interface but it is only for some edge cases such as loading some concrete implementation that your script has no prior knowledge about, if it's incorrect your application can't recover, but this can be avoided anyway I think.

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 ?
