New Comment:
hmm, seems I thought wrongly,
try {
new AAAA();
} catch () {
}
can be catched in 5.3
but
try {
AAA:xxx();
}
can not be catched in 5.3, but can be catched in 5.4.

and the 5.3.0+ seems should be 5.3+ (I mean 5.4 works fine).

"Note:
Prior to 5.3.0, exceptions thrown in the __autoload function could not be
caught
in the catch block and would result in a fatal error. From 5.3.0+ exceptions
thrown in the __autoload function can be caught in the catch block, with 1
provision. If throwing a custom exception, then the custom exception class must
be available. The __autoload function may be used recursively to autoload the
custom exception class."

And please would you mind to show the exact place in the PHP documentation
where it is stated that an autoload handler ALWAYS DIES regardless of
exceptions or substituting another class if it does not find the class it is
trying to load?
Or there is "no information available, might only be in SVN" ???

Sorry but you're wrong. Do you understand what the function
spl_autoload_register() does? And what the function x() does? The function x()
is a handler for loading classes - That is what autoload handler SHOULD DO, it
should LOAD classes which are NOT LOADED yet. And at the moment of loading,
you can not tell whether a class EXISTS or not. The test script is calling a
method of a class which is NOT LOADED yet.
It SHOULD report an error if the class being loaded is not found. But it
SHOULD NOT DIE on throwing an exception!!! This IS A BUG because an exception
is not thrown where it is explicitly written.
You cleverly advise me to use class_exists on a NOT LOADED class, so it just
AGAIN forwards an autoload call to the handler (function "x") which eventually
DIES.
If you are so clever then just remove the autoload handler from PHP and force
use require_once.
Sorry for my being angry, but, damn, it was a HALF-YEAR since bug submitted to
invent such a stupid reason that it is not a bug!!!

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
if you just want to check whether a class exists, use class_exists.
you test script is trying to call a method of a non-exists class, fatal error
is
reasonable .
