Previous Comments: ------------------------------------------------------------------------ [2016-01-13 20:21:17] requinix@php.net https://3v4l.org/HBQRr ($x ?? $y) is defined as being equivalent to (isset($x) ? $x : $y) so __isset() should be getting called. ------------------------------------------------------------------------ [2016-01-13 14:57:50] kostasxx at gmail dot com Description: ------------ The issue appears when using the new null coalescing operator on object parameters, when the defined class has override the magic __get() and an error is triggered inside it. 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.
