Previous Comments: ------------------------------------------------------------------------ [2016-04-19 10:17:29] koubel at seznam dot cz Description: ------------ For classes with implemented __get and __isset, __get is automatically called when testing only if chained overloaded properties are set, despite the first property in chain doesn't exist. There is no reason to call __get anymore. It's there from the beginning of __get/__isset, So maybe it's feature, but undocumented? Test script: --------------- class Xstd {} class XOverloading { function __isset($name) { return FALSE; } function __get($name) { trigger_error('Error', E_USER_WARNING); } } $obj = new Xstd(); var_dump(isset($obj->prop1->prop2)); $obj = new XOverloading(); var_dump(isset($obj->prop1->prop2)); Expected result: ---------------- bool(false) bool(false) Actual result: -------------- bool(false) Warning: Error in .... on line 13 bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72056&edit=1
