5.30以上的版本才能使用,继承了上一版本的快速重定向的特点(单独类,全部使用静态调用),增添了一个很重要的功能和属性,可以调用其他url中的模块了,也使得模块与模块间或页面与页面间的函数简化共享得以实现。
.htaccess文件写法:
-
- #-------------- .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 ---------------
-

重写功能引入:让站点根目录的index.php末尾写上下列代码,重写就开启了(正常条件:1.apache的重写配置成功,且开启了.htaccess支持的.2.站点根目录的.htaccess文件设置好了.3.class.rewrite.php类文件在index.php前面部分加载了.4.页面模块文件位置及写法无误):
代码如下:
-
- //............
- Rewrite::__config(
- $config['path'],/*'http://xxxxx/mysite/'URL基础位置*/
- $config['md_path'],/*'c:/phpsite/www/mysite/modules/'模块文件物理目录*/
- array(
- 'phpinfo'
- )
- );
- Rewrite::__parse();
- //..........
-
复制代码
模块文件写法:
testPk.php
-
-
class Rw_testPk extends Rewrite {
- //这个是前导函数,只要访问到testpk这个页面,这个必然会执行,可用来控制本页面内函数访问权限或本页面全局变量
- public static function init(){
- //if (!defined('SITE_PASS')){
- echo self::$linktag.'
';//self::$linktag是页面解析位置路径值,会常使用.
- //}
- }
- //当访问"http://bbs.it-home.org/testpk/"时会执行
- public static function index(){
- echo 'test';
- }
- //当访问"http://bbs.it-home.org/testpk/blank"时会执行或写作"http://bbs.it-home.org/testpk/index/blank"一般"index/"都是可以被省略的
- public static function blank(){}
- }
- ?>
