Description:
------------
Seems PHP does not support exception catching by parent interface (not
by parent classes). Why? This is a very powerful method to classify
exceptions in programs.
Documentation says that while comparing type in catch block
'instanceof' operator is used, but following test shows that it is
wrong.
I found corresponding code in the source, zend_execute.c:2866, and it
searches for parent classes only. Why not use instanceof_function?
Do you have any perspectives about this problem? Can I wrote in my book
that PHP will support "interface catching" in the future?
Reproduce code:
---------------
<?
interface E {}
class A extends Exception implements E {}
try {
throw new A();
} catch (E $e) {
echo $e;
}
?>
Expected result:
----------------
prints exception data
Actual result:
--------------
Fatal error: Uncaught exception
