For Apache rewrite modules to open and set up is not the subject of this article, please see the other article detailed.
This class can only be used in PHP version 5.30 or more. Inherited the features of the previous version of Fast redirection (separate classes, all using static calls), adding a very important feature and attribute that can invoke the modules in other URLs and make the function simplification sharing between modules and modules or pages and pages possible.
. htaccess file:
Rewrite feature introduction: Let the site root directory at the end of the index.php write the following code, the rewrite is turned on (normal conditions: 1.apache rewrite configuration succeeded, and opened the. htaccess supported by. 2. The. htaccess file of the site root is set up. The 3.class.rewrite.php class file is loaded in the front section of index.php. 4. Page module file location and the correct wording):
<?php
Class rewrite{
public static $debug = false;//Whether debugging is turned on
public static $time _pass = 0;//Gets the overall execution time of the module file
public static $version = 2.2;
public static $pretag = ' rw_ ';//Module file class name prefix
public static $linktag = ' index ';//page link tag, which is used to mark resolution of the link that can be used to control various menu effects and link access rights
protected static $time _start = 0;

protected static $uid = 0;//with personal home page access methods such as http://localhost/423/is access to http://localhost/profile?uid=423
Allowed system functions such as $allow_sys_fun=array (' phpinfo ') then the system will allow links to access phpinfo content, when Http://localhost/phpinfo or http://localhost/ Phpinfo This function directly when/phpinfo, do not need phpinfo.php module file

Internal Cross Module URL resolution calls, such as the execution of Rwrite::__parseurl ('/test2/show ') in the Test1.php module page, will invoke the Show method in the Test2.php module page (rw_ Test2 the method of this class)

This is the resolution of user-defined links (parsed values stored in the database) such as: xiaoming.baidu.com
Database Xiaoming This tag points to a person's blog will go to the www.baidu.com/blog?uid=12 or www.baidu.com/blog?uname=xiaoming (this depends on how I designed the database)
