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*/
- $config['md_path'],/*'c:/phpsite/www/mysite/modules/'模块文件物理目录*/
- array(
- 'phpinfo'
- )
- );
- Rewrite::__parse();
- //..........
-
模块文件写法:
testPk.php
- class Rw_testPk extends Rewrite {
- //这个是前导函数,只要访问到testpk这个页面,这个必然会执行,可用来控制本页面内函数访问权限或本页面全局变量
- public static function init(){
- //if (!defined('SITE_PASS')){
- echo self::$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(){}
- }
- ?>
-
class.rewrite.php;
代码如下:
- class Rewrite{
- public static $debug = false;//是否打开调试
- public static $time_pass = 0;//获得模块文件整体执行时间
- public static $version = 2.2;
- public static $pretag = 'Rw_';//模块文件类的名称前缀
- 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
- protected static $time_start = 0;
- protected static $time_end = 0;
- protected static $physical_path = '';//模块文件的物理路径
- 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
- protected static $ob_contents = '';
- protected static $uid = 0;//配合个人主页访问方式 如http://bbs.it-home.org/423/则是访问http://bbs.it-home.org/profile?uid=423
- //允许的系统函数如$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
- private static $allow_sys_fun = array();
- private static function __get_microtime(){
- list($usec, $sec) = explode(" ",microtime());
- return ((float)$usec + (float)$sec);
- }
- //设置调试Rewrite::__debug(true);
- public static function __debug($d = true){
- static::$debug = $d;
- }
- //配置路径和允许函数
- public static function __config($website_path = '',$physical_path = '',$allow_sys_fun = array()){
- self::$physical_path = $physical_path;

- }
- //调试函数
- public static function __msg($str){

n".print_r($str,true)."n n"; - }
- }
- //解析开始时间

- }
- //解析结束时间
- public static function __end($re = false){

- self::$time_pass = round((self::$time_end - self::$time_start),6) * 1000;
- if($re){
- return self::$time_pass;
- }else{
- self::__msg('PASS_TIME: '.self::$time_pass.' ms');
- }
- }
- //内部跨模块url解析调用,如在test1.php模块页面中执行了Rwrite::__parseurl('/test2/show')这句,将调用test2.php模块页面中的show方法(Rw_test2这个class的方法)
