#48468 [Csd]: empty function confusing

ID: 48468 Updated by: bjori@php.net Reported By: heikki dot leppanen at extendeddisc dot com Status: Closed Bug Type: Translation problem Operating System: windows PHP Version: 5.2.5 Assigned To: bjori New Comment: __isset() is triggered by calling isset() or empty() on inaccessible members. http://no.php.net/manual/en/language.oop5.overloading.php#language.oop5.overloading.members And soon this will be on the isset(), empty() and unset() pages: http://news.php.net/php.doc.cvs/4114 Previous Comments: ------------------------------------------------------------------------ [2009-06-04 09:26:36] heikki dot leppanen at extendeddisc dot com For me it looks like __get() is called. In my experience the only place where this is not working is empty(). class A { var $vars = array('a'=>'aa', 'b'=>'bb'); function __get ($name) { return $this->vars[$name]; } } $x = new A(); if (empty($x->a)) echo "this is empty<br>"; else echo "this in not empty<br>"; echo "x->a::$x->a<br>"; Result is this is empty // This is wrong x->a::aa // This is correct ------------------------------------------------------------------------ [2009-06-04 09:09:03] bjori@php.net This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. The __isset() overloading method is called, not __get() ------------------------------------------------------------------------ [2009-06-04 08:50:06] heikki dot leppanen at extendeddisc dot com OK, now the syntax is correct. This is only example from my code I wrote to demonstrate the confusing with empty() class A { var $vars = array('a'=>'aa', 'b'=>'bb'); function __get ($name) { return $this->vars[$name]; } } $x = new A(); if (empty($x->a)) echo "this is empty<br>"; else echo "this in not empty<br>"; ------------------------------------------------------------------------ [2009-06-04 08:20:03] bjori@php.net That is incorrect too, where are you seeing this? ------------------------------------------------------------------------ [2009-06-04 08:08:33] heikki dot leppanen at extendeddisc dot com It should be like this: var $vars = array{'a'=>'aa', 'b'=>'bb'}; ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
