Pouvez vous mieux expliquer

Bonjour,
voici mon code . vous pouvez me dire ou placer ces codes pour que sa fonctionne
merci davance

// based on ideea http://www.nofunc.com/AJAX_Star_Rating/

// Please if you integrate into HTML Templates, use this file as example
// You will need to copy all from below into your PHP file ...
// For example if you have picture.php, you will need to copy
// first part and second part of the file on proper place.
// You will need to know some PHP

// STEP 1 - copy from here to PHP file

include_once("config.inc.php");

// specifiing the variables that should be used
// EXAMPLE:
// https://www.domain.com/errors/500.html
// will use as rating string "path/index.php"
// usually we need to rate articles by their id's (and other variables)
// in this case the $var_array should be set up
// if you have Artid then will be
// $var_array = array(0=>"Artid");

$var_array = array(0=>"id");

// in this case only https://www.domain.com/errors/500.html$from=12
// will be rated as "path/index.php?id=1" because the rest of the
// url variables are dumped

// Special case:
// if you want to rate only "path/index.php" but you have some url variables
// then you may leave the array blank

// remove the // from the begining of the next line
// $var_array = array();
