Php quick url rewriting instance

Php tutorials can be used only in versions later than 5.30, inheriting the features of fast redirection in the previous version (separate classes, all use static calls ), A very important function and attribute can be added to call the modules in other URLs. This also enables simplified sharing of functions between modules or between pages.
. Htaccess file syntax:
Copy the code as follows:
# --------------. Htaccess start ---------------
RewriteEngine on
RewriteRule !. (Js | ico | gif | jpg | png | css tutorial | swf | htm | txt) $ index. php
Php_flag magic_quotes_gpc off
Php_flag register_globals off
# --------------. Htaccess end ---------------

Rewrite function introduction: Let the index of the site root directory. write the following code at the end of php and rewrite the code (normal condition: 1. apache rewrite configuration is successful and enabled. htaccess supports. 2. the. the htaccess file has been set. 3. class. rewrite. php files are stored in index. php is loaded in the previous part. 4. the file location and writing method of the page module are correct ):
Copy the code as follows:
//............
Rewrite ::__ config (
$ Config ['path'],/* 'http: // xxxxx/mysite/'URL base location */
$ Config ['MD _ path'],/* 'C:/phps tutorial ite/www/mysite/modules/'module file physical directory */
Array (
'Phpinfo'
)
);
Rewrite ::__ parse ();
//..........

Module file syntax:
TestPk. php
Copy the code as follows:
<? Php
Class Rw_testPk extends Rewrite {
// This is a leading function. If you access the testpk page, this function will be executed and can be used to control the function access permission or global variables on this page.
Public static function init (){
// If (! Defined ('site _ pass ')){
Echo self: $ linktag. '<br/>'; // self: $ linktag is the path value of the page resolution location, which is often used.
//}
}
// Executed when accessing "http://www.111cn.net/testpk/"
Public static function index (){
Echo 'test ';
}
// Execute or write "http://www.111cn.net/testpk/blank" when accessing "http://www.111cn.net/testpk/index/blank" generally "index/" can be omitted
Public static function blank (){}
