PHP fast url rewriting updated version [requires PHP 5.30 or above]_PHP tutorial

Opening and setting up the rewrite module of apache is not the subject of this article. Please see other articles for detailed explanations.
This class can only be used in versions above PHP 5.30. It inherits the characteristics of fast redirection from the previous version (single class, all Using static calling), a very important function and attribute is added to call modules in other URLs, which also enables simplified sharing of functions between modules or between pages.
.htaccess file writing method:

Copy code The code is as follows:

#------------- .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 ---------------

Introduction of rewriting function: write the following code at the end of index.php in the root directory of the site, and rewriting will be enabled (normal conditions: 1. Apache rewrite configuration is successful, and .htaccess support is enabled. 2. Site The .htaccess file in the root directory is set up. 3. The class.rewrite.php class file is loaded in the front part of index.php. 4. The page module file location and writing are correct):

Copy code The code is as follows:

//............
Rewrite::__config(
$config[' path'],/*'http://xxxxx/mysite/'URL base location*/
$config['md_path'],/*'c:/phpsite/www/mysite/modules/'Module file physics Directory*/
array(
'phpinfo'
)
);
Rewrite::__parse();
//......

Module file writing method:
testPk.php

Copy code The code is as follows:

< ;?php
class Rw_testPk extends Rewrite {
//This is the leading function. As long as the testpk page is accessed, this will definitely be executed. It can be used to control function access permissions within this page or global variables of this page
public static function init(){
//if (!defined('SITE_PASS')){
echo self::$linktag.'
';//self::$linktag is Page parsing location path value, will be used frequently.
//}
}
//When accessing "http://localhost/testpk/", it will be executed
public static function index(){
echo 'test';
}
//When accessing "http://localhost/testpk/blank", it will be executed or written as "http://localhost/testpk/index/blank". index/" can be omitted
public static function blank(){}
}
?>

class.rewrite.php;

Copy code The code is as follows:
