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 ! ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28333&edit=1
