15php prototype mode

Sometimes the object modifies some part of the property to become part of the new object, and we borrow the clone of the prototype to create a new object.

 
 name = $name;        $this->age = $age;        $this->weight = $weight;    }        function say () {        echo $this->name. '; '. $this->age. '; $this->weight. '; $this->message;    }} Class Dobraisefish extends fish{    function __clone () {        $this->message = ' become braised fish ';    }} Or a live fish $fish = new Dobraisefish (' Grass carp ', 2, ' 2kg '); $Braisefish = Clone ($fish); $Braisefish->say ();

The above describes the 15php prototype model, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
