note 113689 added to language.oop5.static

Don't use GLOBALS in classes (or anywhere really), use static variables instead. They're better. They can do everything a GLOBAL can and they can be protected by accessor functions so they'll never get clobbered. class foo { private static $_private = null; public function get() { if (self::$_private === null) { self::$_private = new stdClass(); } return self::$_private; } } class bar extends foo { } function scope_foo() { $f = new foo(); $f->get()->name = "superdude"; } function scope_bar() { $b = new bar(); $b->get()->description = "an object reference test"; } scope_foo(); scope_bar(); $my = new bar(); foreach ($my->get() as $key => $value) { echo "{$key} => {$value}\n"; } outputs: name => superdude description => an object reference test ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/language.oop5.static.php Edit -- https://master.php.net/note/edit/113689 Del: integrated -- https://master.php.net/note/delete/113689/integrated Del: useless -- https://master.php.net/note/delete/113689/useless Del: bad code -- https://master.php.net/note/delete/113689/bad+code Del: spam -- https://master.php.net/note/delete/113689/spam Del: non-english -- https://master.php.net/note/delete/113689/non-english Del: in docs -- https://master.php.net/note/delete/113689/in+docs Del: other reasons-- https://master.php.net/note/delete/113689 Reject -- https://master.php.net/note/reject/113689 Search -- https://master.php.net/manage/user-notes.php
