PHP quick url rewriting example_PHP tutorial

Only versions 5.30 and above can be used. It inherits the characteristics of fast redirection of the previous version (separate class, all using static calls), and adds a very important function and attribute that can call modules in other URLs. It also enables simplified sharing of functions between modules or between pages

.htaccess file writing method:
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’s rewrite configuration is successful, and .htaccess support is enabled. 2. The .htaccess file in the site 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):
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 physical directory*/
array(
'phpinfo'
)
);
Rewrite::__parse();
//.....

Module file writing method:
testPk.php
The code is as follows:
class Rw_testPk extends Rewrite {
//This is the leading function. As long as the page testpk is accessed, this will definitely be executed. It can be used to control access permissions to functions within this page or global variables of this page
public static function init(){
//if (!defined('SITE_PASS')){
echo self::$linktag.'
';//self::$linktag is the page parsing location path value, which is often used.
//}
}
//Will be executed when accessing "http://www.45it.net/testpk/"
public static function index(){
echo 'test';
}
//When accessing "http://www.45it.net/testpk/blank", it will be executed or written as "http://www.45it.net/testpk/index/blank". Generally, "index/" can be Omitted
public static function blank(){}
}
?>

class.rewrite.php;
The code is as follows:
class Rewrite{
public static $debug = false;//Whether to turn on debugging

public static $version = 2.2;
