Hi all, i have a class with some method that depend by one parameter. What is the best way to write this method?

Example:

First way

class Test{

    var $code;

    function Test($type){
    	if($type=="A"){
    		$this->code=create_function(/*some args and some code*/);
    	}
    	else if($type=="B"){
    		$this->code=create_function(/*some args and some code*/);
    	}
    }

    function use(/*some args*/){
    	return call_user_func($this->code,/*some args*/);
    }
}

Second way

class Test{

    var $type;

    function Test($type){
    	$this->type=$type;
    }

    function use(/*some args*/){
    	if($this->type=="A"){
    		//some code
    	}
    	else if($this->type=="B"){
    		//some code
    	}
    }
}

$test=new Test("A");
$test->use();

Which way you would choose?

Thanks.
