Setter functions are cool.

hmmm, who wants to write setters for 100's of properties? ... see below for an alternative ...

Nevermind, it does need private $foo; it works without it, but not if you want to use a default from within the class. if you set private $foo = 'foo'; print $f->__getFoo(); $f->__setFoo('bar'); print $f->__getFoo();

<?php class Foo { private $foo = 'foo'; function __get($k) { if (isset($this->{$k})) { return $this->{$k}; } throw new Exception("non existing property!"); } function __set($k, $v) { if (isset($this->{$k})) { $this->{$k} = $v; return; } throw new Exception("non existing property!"); } } $f = new Foo; echo $f->foo,"\n"; $f->foo = "bar"; echo $f->foo,"\n";
