本文实例讲述了php实现的网页版剪刀石头布游戏。分享给大家供大家参考，具体如下：
<?php /* * Created on 2016-11-25 * */ if (isset($_POST['sub'])) { $what = $_POST['what']; //需要输入的数组 $my_array = array("剪刀","石头","布"); //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 == $what) { echo "噢，平手"; }elseif (in_array($input,$guize)) { echo "电脑胜"; }else { echo "你赢咯~"; } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>剪刀石头布</title> </head> <body> <form action="" method="post"> <div align="center">剪刀石头布，你出什么？<br/> <input type="radio" name="what" value="剪刀"/>剪刀<br/> <input type="radio" name="what" value="石头"/>石头<br/> <input type="radio" name="what" value="布"/>布<br/> </div> <p align="center"> <input type="submit" name="sub" value="开始！" /> <input type="reset" name="" value="重置" /> </p> </form> </body> </html>
运行效果图如下：
希望本文所述对大家PHP程序设计有所帮助。
