Natedone's note below already shows some ways to implement static class members. There is another way that is based upon returning references, which may be of interest to you. class fooclass { function &staticvar() { static $staticvar; return $staticvar; } function printme() { print($this->staticvar()); } } $foo = new fooclass('foo'); $aid = & $foo->staticvar() ; $aid = "Hello"; $foo->printme(); // Prints "Hello" $aid = & $foo->staticvar() ; $aid = "Foo"; $foo->printme(); // Prints "Foo" This way to implement static class variables has as an advantage that you don't need to suse the same function to set and to get the value of a variable. The disadvantage is that you always need a helper variable. ---- Manual Page -- http://www.php.net/manual/en/language.oop.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39562 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39562&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39562&report=yes Search -- http://master.php.net/manage/user-notes.php
