php5.3以上版本中快速url重寫的方法

#-------------- .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_globals off #-------------- .htaccess end --------------- 複製代碼 重寫功能引入:讓網站根目錄的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支援的.2.網站根目錄的.htaccess檔案設定好了.3.class.rewrite.php類檔案在index.php前面部分載入了.4.頁面模組檔案位置及寫法無誤): //............
