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

Opening and setting up Apache's rewrite module 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 and inherits the fast redirection feature of the previous version (separate class, all using static calls), adding a very important function and attribute that can call modules in other URLs, and 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'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. Page module The 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/'Physical directory of module files*/
array(
'phpinfo'
)
);
Rewrite:: __parse();

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

Module file writing method:

testPk.php

Copy code 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 and 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.
//}
}

//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". Generally, "index/" can be omitted
public static function blank(){}
}
?>

class.rewrite.php;

Copy codeThe code is as follows:

class Rewrite{

public static $debug = false;//Whether to turn on debugging
public static $time_pass = 0;//get Overall execution time of module file
public static $version = 2.2;
public static $pretag = 'Rw_';//Name prefix of module file class

//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 When http://localhost/....../phpinfo, the phpinfo function will be executed directly without the phpinfo.php module file

//Internal cross-module url parsing call, such as executing Rwrite:: in the test1.php module page The sentence __parseurl('/test2/show') will call the show method in the test2.php module page (the method of the Rw_test2 class)
