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=\"\\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 $rules=array( \'^user$\'=>\'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
\\Controller\\User\\User.php
<?php namespace Controller\\User; 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:
