PHP实现路由映射到指定控制器
author:一佰互联 2019-04-26   click:238

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("\", "/", $class);
 $dir=str_replace("\", "/", __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"){
  $_SERVER["PATH_INFO"]="";
  foreach ($_SERVER["argv"] as $k=>$v) {
  if($k==0) continue;
  $_SERVER["PATH_INFO"].="/".$v;
  }
 }
 }
 //路由模式
 public static function router($rules){
 if(isset($_SERVER["PATH_INFO"]) && !empty($rules)){
  $pathInfo=ltrim($_SERVER["PATH_INFO"],"/");
  foreach ($rules as $k=>$v) {
  $reg="/".$k."/i";
  if(preg_match($reg,$pathInfo)){
   $res=preg_replace($reg,$v,$pathInfo);
   $_SERVER["PATH_INFO"]="/".$res;
  }
  }
 }
 }
 //pathinfo处理
 public static function pathInfo(){
 if(isset($_SERVER["PATH_INFO"])){
  $pathinfo=array_filter(explode("/", $_SERVER["PATH_INFO"]));
  for($i=1;$i<=count($pathinfo);$i++){
  $key=isset($pathinfo[$i]) ? $pathinfo[$i] : "";
  $value=isset($pathinfo[$i+1]) ? $pathinfo[$i+1] :"";
  switch ($i) {
   case 1:
   $_GET["m"]=ucfirst($key);
   break;
   case 2:
   $_GET["c"]=ucfirst($key);
   break;
   case 3:
   $_GET["a"]=$key;
   break;
   default:
   if($i>3){
    if($i%2==0){
    $_GET[$key]=$value;
    }
   }
   break;
  }
  }
 }
 $_GET["m"]=!empty($_GET["m"]) ? ucfirst($_GET["m"]) : "Index";
 $_GET["c"]=!empty($_GET["c"]) ? ucfirst($_GET["c"]) : "Index";
 $_GET["a"]=!empty($_GET["a"]) ? $_GET["a"] : "index";
 $class="\Controller\{$_GET["m"]}\{$_GET["c"]}";
 $controller=new $class;
 if(method_exists($controller, $_GET["a"])){
  $controller=new $class;
  $controller->$_GET["a"]();
 }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($e["type"],"<font color="red">Fatal Error</font> ".$e["message"],$e["file"],$e["line"]);
 }
 //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 ? "0".$micseconds : $micseconds;
 if(php_sapi_name()=="cli"){
  $break="
";
 }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
$rules=array(
 "^user$"=>"User/User/getUserList",
 "^user/(d+)$"=>"User/User/getUserById/id/$1",
 "^user/(d+)/article$"=>"User/User/getUserArticle/uid/$1"
);
require_once "SimpleLoader.php";
SimpleLoader::run($rules); 
 

控制器啥样
ControllerUserUser.php

<?php
namespace ControllerUser;

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

效果呢:
