How to implement route mapping to specified controller in PHP

这篇文章主要为大家详细介绍了PHP实现路由映射到指定控制器的相关资料，感兴趣的小伙伴们可以参考一下

自定义路由的功能，指定到pathinfo的url上,再次升级之前的脚本 

SimpleLoader.php

<?php
class SimpleLoader{
 public static function run($rules=array()){
 header("content-type:text/html;charset=utf-8");
 self::register();
 self::commandLine();
 self::router($rules);
 self::pathInfo();
 }
 //自动加载
 public static function loadClass($class){
 $class=str_replace(&#39;\\&#39;, &#39;/&#39;, $class);
 $dir=str_replace(&#39;\\&#39;, &#39;/&#39;, __DIR__);
 $class=$dir."/".$class.".php";
 if(!file_exists($class)){
  header("HTTP/1.1 404 Not Found");
 }
 require_once $class; 
 }
 //命令行模式
 public static function commandLine(){
 if(php_sapi_name()=="cli"){
  $_SERVER[&#39;PATH_INFO&#39;]="";
  foreach ($_SERVER[&#39;argv&#39;] as $k=>$v) {
  if($k==0) continue;
  $_SERVER[&#39;PATH_INFO&#39;].="/".$v;
  }
 }
 }
 //路由模式
 public static function router($rules){
 if(isset($_SERVER[&#39;PATH_INFO&#39;]) && !empty($rules)){
  $pathInfo=ltrim($_SERVER[&#39;PATH_INFO&#39;],"/");
  foreach ($rules as $k=>$v) {
  $reg="/".$k."/i";
  if(preg_match($reg,$pathInfo)){
   $res=preg_replace($reg,$v,$pathInfo);
   $_SERVER[&#39;PATH_INFO&#39;]=&#39;/&#39;.$res;
  }
  }
 }
 }
 //pathinfo处理
 public static function pathInfo(){
 if(isset($_SERVER[&#39;PATH_INFO&#39;])){
  $pathinfo=array_filter(explode("/", $_SERVER[&#39;PATH_INFO&#39;]));
  for($i=1;$i<=count($pathinfo);$i++){
  $key=isset($pathinfo[$i]) ? $pathinfo[$i] : &#39;&#39;;
  $value=isset($pathinfo[$i+1]) ? $pathinfo[$i+1] :"";
  switch ($i) {
   case 1:
   $_GET[&#39;m&#39;]=ucfirst($key);
   break;
   case 2:
   $_GET[&#39;c&#39;]=ucfirst($key);
   break;
   case 3:
   $_GET[&#39;a&#39;]=$key;
   break;
   default:
   if($i>3){
    if($i%2==0){
    $_GET[$key]=$value;
    }
   }
   break;
  }
  }
 }
 $_GET[&#39;m&#39;]=!empty($_GET[&#39;m&#39;]) ? ucfirst($_GET[&#39;m&#39;]) : &#39;Index&#39;;
 $_GET[&#39;c&#39;]=!empty($_GET[&#39;c&#39;]) ? ucfirst($_GET[&#39;c&#39;]) : &#39;Index&#39;;
 $_GET[&#39;a&#39;]=!empty($_GET[&#39;a&#39;]) ? $_GET[&#39;a&#39;] : &#39;index&#39;;
 $class="\\Controller\\{$_GET[&#39;m&#39;]}\\{$_GET[&#39;c&#39;]}";
 $controller=new $class;
 if(method_exists($controller, $_GET[&#39;a&#39;])){
  $controller=new $class;
  $controller->$_GET[&#39;a&#39;]();
 }else{
  header("HTTP/1.1 404 Not Found");
  echo "404";
 }
 }
 //致命错误回调
 public static function shutdownCallback(){
 $e=error_get_last();
 if(!$e) return;
 self::myErrorHandler($e[&#39;type&#39;],&#39;<font color="red">Fatal Error</font> &#39;.$e[&#39;message&#39;],$e[&#39;file&#39;],$e[&#39;line&#39;]);
 }
 //错误处理
 protected static function myErrorHandler($errno,$errstr,$errfile,$errline){
 list($micseconds,$seconds)=explode(" ",microtime());
 $micseconds=round($micseconds*1000);
 $micseconds=strlen($micseconds)==1 ? &#39;0&#39;.$micseconds : $micseconds;
 if(php_sapi_name()=="cli"){
  $break="\r\n";
 }else{
  $break="<br/>";
 }
 $mes="[".date("Y-m-d H:i:s",$seconds).":{$micseconds}] ".$errfile." ".$errline." line ".$errstr.$break;
 echo $mes; 
 }
 //注册
 public static function register(){
 error_reporting(0);
 set_error_handler(function($errno,$errstr,$errfile,$errline){
  self::myErrorHandler($errno,$errstr,$errfile,$errline);
 });
 register_shutdown_function(function(){
  self::shutdownCallback();
 });
 spl_autoload_register("self::loadClass");
 }
}

如何使用
index.php

<?php
//路由映射
$rules=array(
 &#39;^user$&#39;=>&#39;User/User/getUserList&#39;,
 &#39;^user\/(\d+)$&#39;=>&#39;User/User/getUserById/id/$1&#39;,
 &#39;^user\/(\d+)\/article$&#39;=>&#39;User/User/getUserArticle/uid/$1&#39;
);
require_once "SimpleLoader.php";
SimpleLoader::run($rules);

控制器啥样
\Controller\User\User.php

<?php
namespace Controller\User;

class User{
 public function getUserById(){
 echo "用户信息id {$_GET[&#39;id&#39;]} 的信息";
 }
 public function getUserList(){
 echo "用户列表";
 }
 public function getUserArticle(){
 echo "用户id {$_GET[&#39;uid&#39;]} 的文章列表";
 }
}

效果呢：
