  //获胜规则
  $guize = array(array("剪刀","布"),array("布","石头"),array("石头","剪刀"));
  //取数组中的随机值
  $rand_keys = array_rand($my_array);
  $computer = $my_array[$rand_keys];
  echo "你的".$what."VS ".$computer. "<br/>";
    $input = array($computer,$what);
    //将输入的what和电脑随机产生的值构造成一个数组，再判断在不在获胜规则中
    if (!(in_array($what,$my_array))) {
      echo "请输入 剪刀、石头、布";
      header("location:index.php");
    }
    if ($computer == $what) {
