#33856 [Bgs]: $this shining through

ID: 33856 User updated by: sr at brightlight dot ch Reported By: sr at brightlight dot ch Status: Bogus Bug Type: Class/Object related Operating System: * PHP Version: 5.* New Comment: Well, maybe it is not intended that way anymore, but as long as calling a function that way does not result in an error- message it should be done correctly. A function opens a new scope and within that scope, $this should not be visible (as any other variable from the calling scope). It is clear to me that this problem does not appear for pure static functions, but I happen to have some hybrid functions, that's why I discovered this problem at all. But a question besides this: if calling via :: is only possible with static functions in future - is there still a way for developing hybrid functions that can be called either via -> or :: or is the only possible solution to have two different functions for the same?

Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Mark the function as static. It is only possible to call non static methods as static methods for BC reasons. ------------------------------------------------------------------------ [2005-07-25 23:46:58] sr at brightlight dot ch Description: ------------ If a method is called via object::method(); from within a class method, then inside of the object::method(); the $this from the calling class method is visible. This makes it almost impossible to tell if a method was invoked via -> or :: Reproduce code: --------------- <?php $test = new testclass(); $test->test(); class testclass { function test() { otherclass::staticFunction(); normalFunction(); } } class otherclass { function staticFunction() { echo "staticFunction: ".(isset($this) ? "set and of class: ".get_class($this)."\n" : "not set\n"); } } function normalFunction() { echo "normalFunction: ".(isset($this) ? "set and of class: ".get_class($this)."\n" : "not set\n"); } ?> Expected result: ---------------- staticFunction: not set normalFunction: not set Actual result: -------------- staticFunction: set and of class: testclass normalFunction: not set ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33856&edit=1
