Summary: class_exists fails to return for missing dependent
classes
-Status: Open
+Status: Bogus
Type: Bug
Package: Class/Object related
Operating System: FreeBSD 8.1-RELEASE
PHP Version: 5.2.14

New Comment:
You're suppressing errors with the @ operator in the include_once call
-- because there's no MyBaseClass.php file, the autoload fails, which
results in a fatal error when class MyBaseClass can't be found. Without
the @ operator, you get two warnings, then the fatal error, which is
silenced in your code.
Not a PHP bug -> closing.

Description:
------------
If you call class_exists( $sClass ) which in turn triggers an autoloader
that
fails to load a dependent class of $sClass e.g. where $sClass extends a
missing
class, then class_exists fails silently and never returns.
Note this only fails on missing dependent classes if the original class
fails to
load then class_exists returns false as expected.
Also tested on 5.3.3 same results
Test script:
---------------
Test case files here:
http://www.multiplaygameservers.com/dropzone/php-autoload-failure.tar.gz
Expected result:
----------------
factory: MyClass
autoload: MyClass
including: MyClass
autoload: MyBaseClass
including: MyBaseClass
included: for MyBaseClass,
Failed to autoload: MyClass
Failed to load 'MyClass'
Actual result:
--------------
factory: MyClass
autoload: MyClass
including: MyClass
autoload: MyBaseClass
including: MyBaseClass
included: for MyBaseClass,
<-- Nothing more -->
Running with missing initial class:
factory: MyClass
autoload: MyClass
including: MyClass
included: for MyClass,
Failed to autoload: MyClass
Failed to load 'MyClass'
