 New Comment:

Note that it'll be automatically chainable because the result of ->toLower() is 
a 
string and it will cast as an object...

And you'll can also do something like this:
echo 'My String'->toLower();


Just suggestions.. comment.

Description:
------------
It would be nice if we can control the casting behavior of any type to another.

Like a function like this:

register_casting_behavior( $from, $to, $callback_function );

So when you do this:
register_casting_behavior( 'int', 'bool', 'int2bool' );
$X = (bool) 1;

It will call int2bool( 1 ) and so...

Then....

Test script:
---------------
register_casting_behavior( 'string', 'object', array( 'String', '__construct' ) 
);

class String
{
   protected $value = null;
   
   public function __construct( $String )
   {
      $this->value = $String;
      
      return $this;
   }
   
   public function toLower()
   {
      return strtolower($this->value);
   }
   
   public function underline()
   {
      return "<span style='text-decoration: underline;'>{$this->value}</span>";
   }
}

$S = 'My String';

echo $S->toLower()->underline();

// will output: <span style='text-decoration: underline;'>my string</span>
