php實作url路由分發功能的方法:首先要在伺服器的配置上對【/router/】路徑進行攔截;然後實現路由分發器,並取得請求的uri;最後進行模組的編寫。

php實作url路由分送功能的方法:
第一步,首先要在伺服器的設定上對/router/路徑進行攔截
index.php頁面,假定現在所有模組使用單獨的檔案存放於class目錄下,目錄與router平級,如下圖所示:
<!Doctype html> <html> <head> <title>路由测试~~</title> <meta http-equiv="content-type" content="text/html; charset=utf-8" /> </head> <body> <?php date_default_timezone_set("Asia/Shanghai"); define("MODULE_DIR", "../class/"); $_DocumentPath = $_SERVER['DOCUMENT_ROOT']; $_FilePath = __FILE__; $_RequestUri = $_SERVER['REQUEST_URI']; $_AppPath = str_replace($_DocumentPath, '', $_FilePath); //==>\router\index.php $_UrlPath = $_RequestUri; //==>/router/hello/router/a/b/c/d/abc/index.html?id=3&url=http: $_AppPathArr = explode(DIRECTORY_SEPARATOR, $_AppPath); /** * http://192.168.0.33/router/hello/router/a/b/c/d/abc/index.html?id=3&url=http: * * /hello/router/a/b/c/d/abc/index.html?id=3&url=http: */ for ($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'] = $_AppPathArr[0]; $arr_url['method'] = $_AppPathArr[1]; if ($_AppPathArr_Count > 2 and $_AppPathArr_Count % 2 != 0) { die('参数错误'); } else { for ($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']; $module_file = MODULE_DIR.$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, $method_name)) { die("要调用的方法不存在"); } else { if (is_callable(array($obj_module, $method_name))) { $obj_module -> $method_name($module_name, $arr_url['parms']); $obj_module -> printResult(); } } } else { die("定义的模块不存在"); } ?> </body> </html>
<?php class Hello { private $_name; private $_varValue; function __construct() { } function router() { $this->_name = func_get_arg(0); $this->_varValue = func_get_arg(1); } function printResult() { echo $this->_name; echo "<p>"; echo var_dump($this->_varValue); echo "</p>"; } } ?>
