PHP的路由是什么还有什么通俗的说法吗

你所说的路由其实和路由器是一个道理, 通过一个入口接受请求, 然后通过（URL)匹配规则将请求分发到不同的地方。具体到一些主流框架上面，Router模块会配合Http模块分析请求，并且按照一定规则解析去匹配路由，然后使用调度模块使逻辑调到某块代码（通常是控制器），最后返回响应(Response)。

所以说你就把这种路由当做家里用来上网的路由器，道理是一样的。

例如侦测到用户的访问链接是 http://fuck.io/article/1，就会去调用 ArticleController 的 showArticle($id)，并把后面一个 1 当成参数传进去赋值给 $id。

路由本身的定义就是信息传递者，在这里是给请求指路的意思。

url分派到对应处理逻辑上

所谓路由就是当前比较热门的单入口网站的一种做法，我们只访问这个文件：index.php ，比如我们访问http://域名/index.php?class=xxxx&method=xxxxx ，意思就是执行某类里面的某个方法。传的参数不同，那么执行的方法也不同。看见了吧所有的东西都根据传入的参数来决定执行那些代码。

路由就是一个有很多交叉路的路口，不同的人从不同的路（不同的url）来到这里，通过交警给他们指路（路由分发），都找到了他的去路，奔着他们的目的地去了。

原来写的php程序里叫url,但这样叫不够上档次,后来出了300多个php框架,改叫路由了,url立马高端大气上档次
