php initialize static variable with other static variable

Question

I tried to initialize a static var with the content of another one and it seems to fail.

class Hey {
    static $user = "peter";
    static $home = '/home'.Hey::$user;

    // syntax error, unexpected T_VARIABLE, expecting T_STRING

Why does it fail and is there a way without an init-function or something else?

guys don't fool him ?! it's simply not possible as initializions must be constant they are not allowed to use variables at all! — Christoph Diegelmann, Aug 23 '13 at 09:04

class Hey {
    static $user = "peter";
    static $home;
}
Hey::$home =  '/home'.Hey::$user;

or if $home is private:

class Hey {
    static $user = "peter";
    private static $home;
    static function init(){self::$home = '/home'.self::$user;}
}
Hey::init();
