Be very careful to define __set_state() in classes which inherit from a parent using it, as the static __set_state() call will be called for any children. If you are not careful, you will end up with an object of the wrong type. Here is an example:
<?php
class A
{
public $var1;
public static function __set_state($an_array)
{
$obj = new A;
$obj->var1 = $an_array['var1'];
return $obj;
}
}
class B extends A {
}
$b = new B;
$b->var1 = 5;
eval('$new_b = ' . var_export($b, true) . ';');
var_dump($new_b);
?>
