The script runs the __get() method and not the __isset(), so the error on __get() is triggered when the operator is used. Test script: --------------- http://www.pastebucket.com/97499 Expected result: ---------------- The expexted result should be not to trigger the error within the __get() method GET string(6) "value1" GET string(7) "default" Actual result: -------------- The error is triggered GET string(6) "value1" GET PHP Notice: Property attribute2 does not exist in /var/www/html/test.php on line 23 PHP Stack trace: PHP 1. {main}() /var/www/html/test.php:0 PHP 2.
