Super simple method for Implementing Pseudo URLs in php _ php instance

In php, the super-Simple Method of Implementing Pseudo URLs [convert] is like the address path in my log, so that index. php? Action = one & do = two
Changed :? Index/action/one/do/two

The Code is as follows:

Index. php
--------------

// PARSING QUERY STRING
$ QS = explode ("&", $ _ SERVER ['query _ string']);
$ QS = explode ('/', $ QS [0]);

// IF Modul is Undefined set it to index
If (! $ QS [0]) $ MODUL = 'index ';
Else $ MODUL = strtolower ($ QS [0]);

// WE can make a Variable $ _ QUERY
// For alternative _ GET
For ($ I = 1; $ I {
$ _ QUERY [$ NVAR] = $ NVAR = $ QS [$ I];
$ NVAR = $ QS [$ I + 1];
}

// Check the Modul is exists?
If (! File_exists ("modul_directory/{$ MODUL}. php "))
$ MODUL = "index ";

#### THIS IS EXAMPLE TO IMPLEMENTATION THE SCRIPT
// Load The Template
Include ("template. php ");
// Load The Module
Include ("modul_directory/{$ MODUL}. php ");
// Load The Footer
Include ("footer. php ");

?>

We can access the modul in URL like this:
======================================

Www.example.com /? Forum/topic/20
-It mean load the modul forum. php, and set the _ QUERY ['topic '] = 20

Www.foo.com /? Voting/id/54/type/piechart & choice = 2
-It mean load the modul voting. php, and set the _ QUERY ['id'] = 54 and _ QUERY ['type'] = 'piechar' and set _ GET ['choice'] = 2
