zit, make the dropdown form, action="changeLang.php"

next, you will need to either use a cookie/session to store their language choice, or put it in the URL

PHP Code:

/* changeLang.php */

$_SESSION['Language'] = $_POST['Language'];

// setcookie("Language", $_POST['Language'], time() + 3600);

// URL method will require you to add the QUERY STRING to all pages. might get tough

if($Language == 'English') {

  include 'English.php';

} 

PHP Code:

/* English.php */

$Lang = array(

 "SiteName" => "PT",

 "Greeting" => "Hello"

); 

PHP Code:

/* Other.php */

$Lang = array(

 "SiteName" => "Lhsd",

 "Greeting" => "Sjhsdf"

); 

PHP Code:

/* SomePage.php */

echo $Lang['SiteName']; // if they included English.php, this variable will be set as PT, if they included Other.php, it will be set as Lhsd
