Description:
------------
The default behaviour of class_exists calling __autoload breaks BC for
end user scripts which rely on other code outside that users control
(ie PEAR classes).
Many PEAR classes such as Calendar and DB_DataObject use class_exists
to load other classes...
Simply adding an __autoload function to a script using these classes
generates a Fatal error.
An option was added to allow a class_exists($name, FALSE) call to
prevent an __autoload call... but as end users don't have control over
things like PEAR classes, this isn't a viable fix to bug #28333.
Perhaps more reasonably, class_exists should not call __autoload by
default so as to maintain BC... and allow users to explicity request
that behaviour with a second parameter of TRUE.
Reproduce code:
---------------
require_once('Calendar/Calendar.php');
$cal = new Calendar();
function __autoload($name) {
require_once($name);
}
Expected result:
----------------
Expect no output (ie no errors).
Actual result:
--------------
Warning: __autoload(Calendar_Engine_UnixTS): failed to open stream: No
such file or directory in /home/james/test.php on line 8
Fatal error: __autoload(): Failed opening required
'Calendar_Engine_UnixTS' (include_path='.:/usr/local/lib/php') in
/home/test.php on line 8
