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

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($e['type'],'Fatal Error '.$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="
";

}

$mes="[".date("Y-m-d H:i:s",$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

//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

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：
