You can use ReflectionProperty::setValue to set the value on static properties as well as regular instance properties.  Simply pass null in place of the instance:

<?php
class Foo {
    protected static
$bar = null;
    public static function
sayBar() {
        echo
self::$bar;
    }
}

$r = new ReflectionProperty('Foo', 'bar');
$r->setAccessible(true);
$r->setValue(null, 'foo');

Foo::sayBar(); // "foo"
?>
