MVC中去掉index.php（优雅的使用url）

来源：互联网发布：淘宝众筹万创中国编辑：程序博客网时间：2024/05/22 09:44

前段时间写了一篇MVC中的简单路由。
后来发现，该文章实现的功能，支持controller里面的路径，已经url参数的设置，因此，今天把优化的代码贴上。
config.php

<?php/** * Created by PhpStorm. * User: koastal * Date: 2016/5/15 * Time: 10:48 */define("APP_PATH",substr(__DIR__,0,strlen(__DIR__)-5));define("Controller_PATH",APP_PATH.DIRECTORY_SEPARATOR."controller");define("Model_PATH",APP_PATH.DIRECTORY_SEPARATOR."model");define("View_PATH",APP_PATH.DIRECTORY_SEPARATOR."view");define("Lib_PATH",APP_PATH.DIRECTORY_SEPARATOR."libs");

Loader.php

<?php/** * Created by PhpStorm. * User: koastal * Date: 2016/5/15 * Time: 12:03 */require_once 'config.php';class Loader{    public  static function baseLoad()    {        require_once("Controller.php");        require_once("Model.php");    }    public static function searchFile($filename,$path)    {        $filePath = false;        $list = scandir($path);        foreach($list as $file){            $realPath = $path.DIRECTORY_SEPARATOR.$file;            if(is_dir($realPath) && $file!='.' && $file!='..'){                $res = Loader::searchFile($filename,$realPath);                if($res){                    return $res;                }            }elseif($file!='.' && $file!='..'){                if($file == $filename){                    $filePath = $realPath;                    break;                }            }        }        return $filePath;    }    public static function autoload($class)    {        $filename = $class.".class.php";        $cflag = Loader::searchFile($filename,Controller_PATH);        $mfalg = Loader::searchFile($filename,Model_PATH);        $path = false;        $path = ($cflag != false)? $cflag:$path;        $path = ($mfalg != false)? $mfalg:$path;        if($path == false){            exit("Class Load Failed.");        }else{            require_once($path);        }    }}Loader::baseLoad();spl_autoload_register(array('Loader', 'autoload'));

router.php

<?php/** * Created by PhpStorm. * User: koastal * Date: 2016/5/15 * Time: 15:09 */require_once("config.php");require_once("Loader.php");$path = isset($_SERVER['PATH_INFO'])? $_SERVER['PATH_INFO']:null;$path = str_replace("index.php/",'',$path);$path_array = explode("/",$path);array_shift($path_array);   //得到完整参数if(count($path_array)<3){    switch(count($path_array)){        case 2:            $controller = $path_array[0];            $function = $path_array[1];            break;        case 1:            $controller = $path_array[0];            $function = "index";            break;        case 0:            $controller = "index";            $function = "index";            break;    }}else{    $param = array();   //参数    foreach($path_array as $num=>$name){        $temp_dir = Controller_PATH."/".$name;        if(is_dir($temp_dir)){            array_shift($path_array);            continue;        }else{      //控制器            $controller = isset($path_array[$num])? $path_array[$num]:'index';            $function = isset($path_array[($num+1)])? $path_array[($num+1)]:'index';            array_shift($path_array);array_shift($path_array);            $param = $path_array;            break;        }    }    if(!empty($param)){ //处理参数        for($i=0;$i<count($param);$i=$i+2){            $key = $param[$i];            $value = isset($param[($i+1)])? $param[($i+1)]:null;            $_GET[$key] = $value;        }    }}$controller .= "Controller";$controller_obj = new $controller;$controller_obj->$function();?>

与上一篇文章的优化之处就是增强了对$path_array的判断，首先判断前面的参数是否为路径，如果为路径则从数组中弹出，直到取到控制器和方法，然后将控制器和方法也从数组中弹出，剩下的就是url传递给方法的参数了。

全文完。
