How about this?

class String {

    protected $string='';
   
    public function __construct($string){
        $this->string = $string;
    }

    public function toUpper(){
        $string = clone $this;
        $string->string = strtoupper($this->string);
        return $string;
    }

    public function __toString(){
        return $this->string;
    }

}

$foo = new String('foo');
$bar = $foo->toUpper();
echo $foo; //foo
echo $bar; //FOO

So far we only have the toString magic method. If we had the others, you
could conceivably do this all in userland (at a fairly high performance
cost I would assume).

Cheers,
