php快速url重写实例代码

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:

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 off
7. #-------------- .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:

2. //............
3. Rewrite::__config(
4. $config['path'],/*'http://xxxxx/mysite/'URL基础位置*/
5. $config['md_path'],/*'c:/phpsite/www/mysite/modules/'模块文件物理目录*/
6. array(
7. 'phpinfo'
8. )
9. );
10. Rewrite::__parse();
11. //..........

模块文件写法: testPk.php

2. class Rw_testPk extends Rewrite {
3. //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
4. public static function init(){
5. //if (!defined('SITE_PASS')){
6. echo self::$linktag.'
   ';//self::$linktag是页面解析位置路径值,会常使用.
7. //}
8. }
9. //当访问"http://bbs.it-home.org/testpk/"时会执行
10. public static function index(){
11. echo 'test';
12. }
13. //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
14. public static function blank(){}
15. }
16. ?>

class.rewrite.php; 代码如下:

2. class Rewrite{
3. public static $debug = false;//是否打开调试
4. public static $time_pass = 0;//获得模块文件整体执行时间
5. public static $version = 2.2;
6. public static $pretag = 'Rw_';//模块文件类的名称前缀
7. public static $linktag = 'index';//页面链接标记,用来标记解析的是那个链接,可用来控制各种菜单效果和链接访问权限
8. protected static $time_start = 0;
9. protected static $time_end = 0;
10. protected static $physical_path = '';//模块文件的物理路径
11. protected static $website_path = '';//模块文件的站点路径,因为可能把站点放大站点的子目录下,如:http://bbs.it-home.org/site/mysite
12. protected static $ob_contents = '';
13. protected static $uid = 0;//配合个人主页访问方式 如http://bbs.it-home.org/423/则是访问http://bbs.it-home.org/profile?uid=423
14. //允许的系统函数如$allow_sys_fun=array('phpinfo')那么系统将允许链接访问phpinfo内容了,当http://bbs.it-home.org/phpinfo或http://bbs.it-home.org/......./phpinfo时就会直接执行phpinfo这个函数,不需要phpinfo.php模块文件
15. private static $allow_sys_fun = array();
16. private static function __get_microtime(){
17. list($usec, $sec) = explode(" ",microtime());
18. return ((float)$usec + (float)$sec);
19. }
20. //设置调试Rewrite::__debug(true);
21. public static function __debug($d = true){
22. static::$debug = $d;
23. }
24. //配置路径和允许函数

34. }
