Here is a simple example of how to have Language Files which allows you to easily display your site in multiple languages. Even if you only wish your website to use one language, using language files is a must for any big or growing website because it allows for changing text across whole site, from just one simple file. This example only shows the concept to do it.

It would be up to you to enable multiple language selection options.

First file, call it: en_US.php. Inside this file we will place two language definitions:
<?php

$messages
['test_one']    = 'I am test one!';
$messages['test_two']    = 'I am test two!';

?>



Ok, now for the function we will use to always access the language file.
Call this file: lang.function.php
Inside this file we put the following code:
<?php

   
function getLang($lang)
    {
        global
$messages;

       
$display_message = $messages[$lang];

        return
$display_message;
    }

?>


We make $messages be a global because it is easier to access the $messages within
the en_US.php file this way.
The $lang is what determines which message we want from our en_US.php file.


Ok, now make a file called: test.php
and within this file include this:
<?php

include('en_US.php');
include(
'lang.function.php');

//test one
echo getLang('test_one');
echo
"<br />";

//test two
echo getLang('test_two');

?>


And there ya have it!
A simple easy way to contain text on your website to one central location.

I use my lang file in the following way :
$text[1]=`ja`;$text[2]=`yes`;$text[3]=`oui];
where 1= dutcht 2=english 3 =  french
This lets met add an endless list of languages.
or when i make a query where the text of the same subject is in de DB
"Select `a`,`b`,`c".$lang."` from `table`";
wich gives me:
Select `a`,`b`,`c1` from ` table ` 
where field c+$lang &gt;&gt; c1 contains the dutch text or c2 the english version or c3 the french version
