5.30以上的版本才能使用,繼承了上一個版本的快速重定向的特點(單獨類,全部使用靜態調用),增添了一個很重要的功能和屬性可以調用其他url中的模塊了也使得模塊與模塊間或頁面與頁面間的函數簡化共享得以實現

.htaccess文件寫法:

#-------------- .htaccess start ---------------

RewriteEngine on

RewriteRule !.(js|ico|gif|jpg|png|css教程|swf|htm|txt)$ index.php

php_flag magic_quotes_gpc off

php_flag register_globals off

#-------------- .htaccess end ---------------

重寫功能引入:讓站點根目錄的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支持的.2.站點根目錄的.htaccess文件設置好了.3.class.rewrite.php類文件在index.php前面部分加載了.4.頁面模塊文件位置及寫法無誤):

//............

Rewrite::__config(

$config['path'],/*'http://xxxxx/mysite/'URL基礎位置*/

$config['md_path'],/*'c:/phps教程ite/www/mysite/modules/'模塊文件物理目錄*/

array(

'phpinfo'

)

);

Rewrite::__parse();

//..........

模塊文件寫法: testPk.php

<?php

class Rw_testPk extends Rewrite {

//這個是前導函數,只要訪問到testpk這個頁面,這個必然會執行,可用來控制本頁面內函數訪問權限或本頁面全局變量

public static function init(){

//if (!defined('SITE_PASS')){

echo self::$linktag.'<br/>';//self::$linktag是頁面解析位置路徑值,會常使用.

//}

}

//當訪問"http://www.49028c.com/testpk/"時會執行

public static function index(){

echo 'test';

}

//當訪問"http://www.49028c.com/testpk/blank"時會執行或寫作"http://www.49028c.com/testpk/index/blank"一般"index/"都是可以被省略的

public static function blank(){}

}

?>

class.rewrite.php;

<?php

class Rewrite{

public static $debug = false;//是否打開調試

public static $time_pass = 0;//獲得模塊文件整體執行時間

public static $version = 2.2;

public static $linktag = 'index';//頁面鏈接標記,用來標記解析的是那個鏈接,可用來控制各種菜單效果和鏈接訪問權限

protected static $time_end = 0;

//允許的系統函數如$allow_sys_fun=array('phpinfo')那么系統將允許鏈接訪問phpinfo內容了,當http://www.49028c.com/phpinfo或http://www.49028c.com/......./phpinfo時就會直接執行phpinfo這個函數,不需要phpinfo.php模塊文件

private static $allow_sys_fun = array();

//內部跨模塊url解析調用,如在test1.php模塊頁面中執行了Rwrite::__parseurl('/test2/show')這句,將調用test2.php模塊頁面中的show方法(Rw_test2這個class的方法)
