哈哈 我来分享一下我自己写的路由解析类啦

摘要：<?php class Route {     //保存路由配置信息     protected $route = [];     //保存url路径信息     protected 

<?php
class Route
{
    //保存路由配置信息
    protected $route = [];
    //保存url路径信息
    protected $pathinfo = [];
    //保存url参数
    protected $param = [];

    public function __construct($route)
    {
        $this->route = $route;
    }
    //解析路由
    //http://frame.io/[index.php]/admin/Index/index
    public function parse($url)
    {
        if(strpos($url,'.php')){
            $queryStr = strchr($url,'.php');
            $queryStr = trim(substr($queryStr,4),'/');
        }else{
            $domainLen = strlen($_SERVER['SERVER_NAME']);
            $queryStr = strchr($url,$_SERVER['SERVER_NAME']);
            $queryStr = trim(substr($queryStr,$domainLen),'/');
        }
        $queryArr = explode('/',$queryStr);
        //$queryArr = array_filter($queryArr);
        switch (count($queryArr)){

                $this->pathinfo = $this->route;
                break;

老师总结：你完全可以用自己的方式进行测试, 没有必要照抄老师的代码, 这个框架你写完, 基本上对现代框架的运行流程就理解了, 再学其它商业框架,就非常轻松了, 因为你从底层理解了
