PHP does not catch Exception (namespace)

Question

to sum it up: I've got an exception-class (\core\exceptions\GuruMeditationException) that extends from \Exception. Every other exception class simply extends from my own exception class. When my code runs and an exception is thrown everything works perfect for me.

Now: Assume I have a class (\app\HomeView) that extends from \core\base\mvc\View. Exceptions thrown in there are caught fine, too. The class declaration looks like this:

namespace app;
class HomeView extends \core\base\mvc\View {
}

But: If I do the following:

namespace app;
class HomeView extends \core\base\mvc\DoesNotExist {   # line 5
}

then no exception is caught anymore. I've already tried to catch all exceptions i created, with and without namespace. I also tried to catch 'Exception' and '\Exception' but nothing will help. Instead I get an error similar to that:

Fatal error: Class 'core\base\mvc\DoesNotExistView' not found in /var/www/abuhome/htdocs/test-namespace/class/HomeView.class.php on line 5

Can anyone help me please? I think I've forgot something, but I can't figure out what it is >.<

thank you

You cannot catch or stop fatal errors, they are fatal.

A syntax error is not an exceptional circumstance.

hum ok. I don't think this is a syntax error - fatal, ok - but in my opinion this should be catchable =/

NikiC Over a year ago

@TristanCebulla You can catch it via an autoloader if you really, really want to ;)

Phil Over a year ago

@TristanCebulla Perhaps "syntax error" is not entirely accurate. More of a compilation / parse error

Tristan Cebulla Over a year ago

i already have an autoloader (the uses() function), but that does not prevent from fatal typing errors when extending from a nonexistant class. or is there some namespace/autoload-magic i don't know?

Phil Over a year ago

@TristanCebulla What do you hope to achieve by catching an error like this? Your code can obviously not continue to be parsed as compilation will be impossible
