Summary: instanceof does not complain even if class is never
defined
Status: Bogus
Type: Bug
Package: Compile Failure
Operating System: Ubuntu Linux
PHP Version: 5.3.6

New Comment:
Yeah, autoloader should try to load the class and then, if unsuccessful - fail.
Seriously. I know that it's cool to have funny glitches in PHP like FOO
reverting to 'FOO' if it's undefined, but this?

Think of autoloader, or other related tests. A warning or error here is not
welcome.

How it's possibly useful to test if object is an instance of class which is not
even defined?

That's the exact idea of instanceof to test something without getting noises.

Description:
------------
PHP does not complain if you check for non-existant class with instanceof.
This provides space for subtle errors, like checking for DateRange when only
Date_Range class is defined.
Test script:
---------------
<?php
echo PHP_VERSION . "\n";
error_reporting(E_ALL);
class Foo {}
$a = new Foo;
// Notice that Bar class is never defined, however PHP does not complain about
missing class.
if ($a instanceof Bar) { echo "Should be an error\n"; }
else { echo "PHP fail\n"; }
Expected result:
----------------
Compiler error thrown saying that Bar was not found.
Actual result:
--------------
Nothing happens.
