Bug description: class_exists call __autoload
Description:
------------
I've a function __autoload in my script. I want to use class_exists to
determine if a class definition has been included but i don't want to load
it.
However, class_exists call __autoload systematically when a class
definition hasn't been loaded.
This problem poses problems of compatibility with previous versions.
Indeed, many scripts used this function before using a include.
Reproduce code:
---------------
function __autoload($classname) {
echo 'i want to load ['.$classname.']<br>';
}
class A {}
if (class_exists('B') == false)
echo "Class B don't exist !<br>";
else
echo "Class B exist !<br>";
if (class_exists('A') == false)
echo "Class A don't exist !<br>";
else
echo "Class A exist !<br>";
Expected result:
----------------
Class B don't exist !
Class A exist !
Actual result:
--------------
i want to load [B]
Class B don't exist !
Class A exist !
