在PHP中,利用單一入口文件實現路徑的訪問,實現形如 http://localhost/project/index.php/module/method/param_key/param_val 的訪問路由php
module:模塊名稱(類)url
method:模塊方法code
param_key:參數名稱路由
param_val:參數值hash
1、新建項目 routeio
在 route 下新 index.php,代碼以下function
<?php error_reporting(0); define(DIR_CONTROLLER, 'controller/'); // 定義控制器目錄 date_default_timezone_set("Asia/Shanghai"); $_DocumentPath = $_SERVER['DOCUMENT_ROOT']; $_RequestUri = $_SERVER['REQUEST_URI']; $_UrlPath = $_RequestUri; $_FilePath = __FILE__; $_AppPath = str_replace($_DocumentPath, '', $_FilePath); //==>\route\index.php $_AppPathArr = explode(DIRECTORY_SEPARATOR, $_AppPath); for ($i = 0; $i < count($_AppPathArr); $i++) { $p = $_AppPathArr[$i]; if ($p) { $_UrlPath = preg_replace('/^\/'.$p.'\//', '/', $_UrlPath, 1); } } $_UrlPath = preg_replace('/^\//', '', $_UrlPath, 1); $_AppPathArr = explode("/", $_UrlPath); $_AppPathArr_Count = count($_AppPathArr); $arr_url = array( 'controller' => 'Index', 'method' => 'index', 'parms' => array() ); $arr_url['controller'] = ucfirst($_AppPathArr[0]); // 模塊名稱,首字母轉爲大寫 $arr_url['method'] = $_AppPathArr[1]; // 獲取參數 if ($_AppPathArr_Count > 2 and $_AppPathArr_Count % 2 != 0) { //die('參數錯誤'); } else { for ($i = 2; $i < $_AppPathArr_Count; $i+=2) { $arr_temp_hash = array(strtolower($_AppPathArr[$i])=>$_AppPathArr[$i + 1]); $arr_url['parms'] = array_merge($arr_url['parms'], $arr_temp_hash); } } $module_name = $arr_url['controller']; $module_file = DIR_CONTROLLER.$module_name.'.class.php'; $method_name = $arr_url['method']; if (file_exists($module_file)) { include $module_file; $obj_module = new $module_name(); if (!method_exists($obj_module, $method_name)) { die("要調用的方法不存在"); } else { if (is_callable(array($obj_module, $method_name))) { $obj_module -> $method_name($arr_url['parms']); } } } else { die("定義的模塊不存在"); } ?>
2、在項目目錄下新建 controller 文件夾,並在該文件夾下新建 Welcome.class.php 文件,代碼以下class
<?php class Welcome{ public function index($param){ echo 'Hello World!'; } } ?>
3、地址欄輸入 http://localhost/route/index.php/welcome/index/module
頁面輸出 「 Hello World! 」date
