This behavior is inconsistent and prone to cause confusion amongst users. I'd like to suggest that property_exists just returns false if the first argument is not an object, like method_exists does. Best regards, Lucas Test script: --------------- <?php var_dump( method_exists(null, 'foo') ); var_dump( property_exists(null, 'foo') ); Expected result: ---------------- property_exists returns false if the first argument is not an object Actual result: -------------- property_exists throws a warning if the first argument is not an object ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79462&edit=1
