Which way is Better? OOP

[JREAM]

// way 1... (But im not sure how I can hold the errors inside the Blah class) everytime an item is called
class Blah {
public function __construct()
{
	$this->slice = new Slice();
	$this->thumb = new Thumb();
}
}

$blah = new Blah();
$blah->slice->file('test.jpg');

// Way 2
class Blah {

public function __construct()
{
	$this->_slice = new Slice();
	$this->_thumb = new Thumb();
}

public function slice($arg)
{
	$this->_slice->{$arg[0]}($arg[1])
}

public function thumb($arg)
{
	$this->_thumb->{$arg[0]}($arg[1])
}

}

$blah = new Blah();
$blah->slice('file', 'test.jpg');

I'll just leave this here...

(holding errors inside of blah. you will need to edit other classes as well, I imagine.)
