php能写单机游戏，其实现方法如：首先创建一个“control.php”以及“main.php”文件；然后创建一个“tcs.php”文件；最后通过session记录位置来制作单机游戏即可。
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：
