Callback functions in php and exceptions

Question

Currently I'm reading php's manual about callback functions and found interesting note:

Callbacks registered with functions such as call_user_func() and call_user_func_array() will not be called if there is an uncaught exception thrown in a previous callback.

It's obvious that script run will be interrupted in case of uncaught exception. So, why did authors of php manual additionally write that about call_user_func? Or I misunderstood the statement?

Answer 1

That seems to me more a reminder than part of the doc. All uncaught exceptions are fatal in php, unless they were talking about call_user_func() borking even if you have set a handler (with set_exception_handler) instead of a catch, which sounds like something a lawyer would do..
