  2. #-------------- .htaccess start ---------------
  3. RewriteEngine on
  4. RewriteRule !.(js|ico|gif|jpg|png|css|swf|htm|txt)$ index.php
  5. php_flag magic_quotes_gpc off
  6. php_flag register_globals-- ------------ .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):

  1. //............
  2. Rewrite::__config(
  3. $config['path'] ,/*'http://xxxxx/mysite/'URL基礎位置*/
  4. $config['md_path'],/*'c:/phpsite/www/mysite/modules/'模組檔案實體目錄*/
  5. array(
  6. 'phpinfo'
  7. )
  8. );
  9. Rewrite::__parse();
  10. //..........

模組檔案寫法:

testPk.php

  2. class Rw_testPk extends Rewrite {

  3. //這個是前導函數,只要訪問到testpk,這一點頁面,這個必然會執行,可用於控製本頁面內函數存取權限或本頁面全域變數
  4. public static function init(){
  5. //if (!defined('SITE_PASS')){
  6. echo self::$linktag.'
    ';//self::$linktag是頁面解析位置路徑值,會常使用.
  7. //}
  8. }
  9. //當造訪"http://localhost/testpk/"時會執行
  10. public static function index(){
  11. echo 'test';
  12. }

  13. //當造訪"http://localhost/testpk/blank"時會執行或寫作"http://localhost/testpk/index/blank"一般"index/"都是可以省略的

  14. public static function blank(){}
  15. }
  16. ?>
