5.30以上的版本才能使用,繼承了上一個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中的模塊了 也使得模塊與模塊間或頁面與頁面間的函數簡化共享得以實現
.htaccess文件寫法:
- #-------------- .htaccess start ---------------
- RewriteEngine on
- RewriteRule !.(js|ico|gif|jpg|png|css教程|swf|htm|txt)$ index.php
- php_flag magic_quotes_gpc off
- php_flag register_globals off
- #-------------- .htaccess end ---------------
重寫功能引入:讓站點根目錄的index.php末尾寫上下列代碼,重寫就開啟了(正常條件:1.apache的重寫配置成功,且開啟了.htaccess支持的.2.站點根目錄的.htaccess文件設置好了.3.class.rewrite.php類文件在index.php前面部分加載了.4.頁面模塊文件位置及寫法無誤):
- //............
- Rewrite::__config(
- $config['path'],/*'http://xxxxx/mysite/'URL基礎位置*/
- $config['md_path'],/*'c:/phps教程ite/www/mysite/modules/'模塊文件物理目錄*/
- array(
- 'phpinfo'
- )
- );
- Rewrite::__parse();
- //..........
模塊文件寫法: testPk.php
- <?php
- class Rw_testPk extends Rewrite {
- //這個是前導函數,只要訪問到testpk這個頁面,這個必然會執行,可用來控制本頁面內函數訪問權限或本頁面全局變量
- public static function init(){
- //if (!defined('SITE_PASS')){
- echo self::$linktag.'<br/>';//self::$linktag是頁面解析位置路徑值,會常使用.
- //}
- }
- //當訪問"http://www.companysz.com/testpk/"時會執行
- public static function index(){
- echo 'test';
- }
- //當訪問"http://www.companysz.com/testpk/blank"時會執行或寫作"http://www.companysz.com/testpk/index/blank"一般"index/"都是可以被省略的
