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.

My PHP installation shows behavior which suggests otherwise. From reading the documentation page, it is not clear enough that the magic method could theoretically be declared static in older PHP versions, but that this is discouraged. Reproduce code: --------------- $ php --version|head -n 1;php -r 'class A{}class B{public function __get($n){}}class C{public static function __get($n){}}$a=new A;$b=new B;$c=new C;$a->d;$b->d;$c->d;' PHP 5.2.12-pl0-gentoo with Suhosin-Patch 0.9.7 (cli) (built: Jan 23 2010 22:38:48) Notice: Undefined property: A::$d in Command line code on line 1 If you like another example, you can also try: <?php class A { // expect warning/error message, but do not get any public static function __get($name) { return 'test'; } } $a = new A(); echo $a->b . "\n"; Expected result: ---------------- I suggest adding something like the following after the text “Therefore these methods can not be declared static.”: “*Note:* Before PHP 5.3.0, it was possible to declare these methods static. This is strictly discouraged, and relying on this behavior is deprecated.” Actual result: -------------- Note that the code example gives the same reaction (no warning) for accesses to $b *and* $c. So it does not matter whether the __get method is declared static or not. The documentation changelog mentions: “Added __callStatic(). Added warning to enforce public visibility and non-static declaration.” for version 5.3.0. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50961&edit=1
