在PHP中随机随机播放？

Question

I'm creating a lottery to pair up people. So I want a way to shuffle the strings in an array where no item ends up on the same place. (You can't pair up with yourself)

    public function shuffleSantas(){
    $query = $this->db->get('person');
    $givers = array();
    $recievers = array();
    foreach($query->result() as $row):          
        $givers[] = $row->name;
        //here i want a random order, but no name can be on the same place as in $givers!
        $recievers[] = '';
    endforeach;

Answer 1

If think there is no built-in function in PHP to shuffle that way. You have to write your own function.
