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:
