5.30以上的版本才能使用,繼承了上一版本的快速重定向的特點(單獨類,全部使用靜態調用),增添了一個很重要的功能和屬性,可以調用其他url中的模組了,也使得模組與模組間或頁面與頁間的函數簡化共享得以實現。
.htaccess檔案寫法:
-
- #-------------- .htaccess start -------------- -
- RewriteEngine on
- RewriteRule !.(js|ico|gif|jpg|png|css|swf|htm|txt)$ index.php
- php_flag magic_quotes_gpc off
- php_flag register_p #-------------- .htaccess end ---------------

重寫功能引入:讓站點根目錄的index.php末尾寫上下列程式碼,重寫就開啟了(正常條件:1.apache的重寫配置成功,且開啟了.htaccess支援的.2.站點根目錄的.htaccess檔案設定好了.3.class.rewrite.php類別檔案在index.php前面部分載入了.4.頁面模組檔案位置及寫法無誤):
代碼如下:
- //............
- Rewrite::__config(
- $config['path'] ,/*'http://xxxxx/mysite/'URL基礎位置*/
- $config['md_path'],/*'c:/phpsite/www/mysite/modules/'模組檔案實體目錄*/
- array(
- 'phpinfo'
- )
- );
- Rewrite::__parse();
- //..........

模組檔案寫法:
testPk.php
-
class Rw_testPk extends Rewrite {
- //這個是前導函數,只要訪問到testpk這個頁面,必然執行這個頁,可用來控製本頁內函數存取權限或本頁面全域變數
- public static function init(){
- //if (!defined('SITE_PASS')){
- echo self::$linktag .'
';//self::$linktag是頁面解析位置路徑值,會常使用.
- //}

- //當訪問"http://bbs. it-home.org/testpk/"時會執行
- public static function index(){
- echo 'test';
- }
- //當造訪"http://bbs.it- home.org/testpk/blank"時會執行或寫作"http://bbs.it-home.org/testpk/index/blank"一般"index/"都是可以省略的
