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,
