PHP: Class Hierarchy with static members

I have this system which I'm working on:

abstract class Model {
    static $table = "";
    abstract static function init();

    public static function getById() {
        $table = self::$table;
    }
}

class Model_user extends Model {
    static function init() {
        self::$table = "users";
    }
}

class Model_post extends Model {
    static function init() { self::$table = "post"; }
}

// ...

Model_user::init();
Model_post::init();
$user = Model_user::getById(10);
$post = Model_user::getById(40);

I want it to be so each subclass has its own set of static members which can be accessed by the static functions in Model. I can't use the static:: keyword because I have to use PHP 5.2.16. Unfortunately, I can't just say "self::" because of a problem with PHP revealed in the below example:

class Foo {
    static $name = "Foo";

    static function printName() {
        echo self::$name;
    }
}

class Bar extends Foo {
    static $name = "Bar";
}

class Foobar extends Foo {
    static $name = "Foobar";
}

Bar::printName();
echo "<br />";
Foobar::printName();开发者_Python百科

Which displays:

Foo<br />Foo

When it should display:

Bar<br />Foobar

Any way this could be done?

It seems you cannot access the children classes static members in the parent's static method's code. A solution has been posted in this comment on the php documentation about the static keyword. The solution would be to make your table variable an array of this form:

$table = array ('classname' => 'tablename', 'secondClassname' => 'secondTablename');

Everything that is static belongs to the class, not to an object. Therefore static methods are not inherited from a parent class and will only access members inside the class they are defined in.

In Java this sort of static method call (Foobar::printName()) would even throw an error.
