php能写游戏吗？一定有小伙伴会有这样的疑问。答案是可以，虽然php写大型游戏还是欠缺，但写一些小型的单机游戏的话还是可以的，比如说一些休闲游戏，智力游戏！本文给大家分享的是使用php实现贪吃蛇单机小游戏的代码，其主要思路是通过session记录位置来制作，应该说思路非常巧妙，推荐给大家。
贪吃蛇游戏是一款非常经典的单机手机游戏，既简单又耐玩；简单易上手的游戏玩法，受到了不少玩家的喜爱。通过控制蛇头方向吃蛋，使得蛇变长，从而获得积分。在诺基亚时代，风靡整个手机界，今天我们来看看另类的，如何使用php来实现贪吃蛇小游戏
废话不多说，代码奉上：
control.php
<!doctype html><html> <head> <meta charset="utf-8"/> </head> <body> <a href="control.php?a=up">上<a/> <?session_start(); echo $_session['count'];?>分<br/> <a href="control.php?a=left">左<a/> <a href="control.php?a=right">右<a/><br/> <a href="control.php?a=down">下<a/> <? switch($_get['a']){ case "up"; $_session['con']="up"; break; case "down": $_session['con']="down"; break; case "left": $_session['con']="left"; break; case "right": $_session['con']="right"; break; } ?> </body></html>
main.php
