PHP changing language version - php

Question

I have a website which i want to create other language version.
I don't want to create folder for each language. I was wondering it
it's possible to add a combobox on each page or on the main one
so that user can setup the language then using php i will
check the option and show the right version. Any suggesting
to achive that?

Answer 1

If you have a combobox, when the user submits it, store the language in the session (session_start(); has to be called) with $_SESSION['lang'] = $_POST['lang'];. I'd advise you to whitelist languages as such:
session_start();
// define language whitelist
$allowedLangs = array('en', 'de');
// only store the new user language if it's an allowed one
if (isset($_POST['lang']) && in_array($_POST['lang'], $allowedLangs)) {
$_SESSION['lang'] = $_POST['lang'];
}
// define the user language based on session data or use 'en' as default if not available
$userLang = isset($_SESSION['lang']) ? $_SESSION['lang'] : 'en';
// parse some language file according to the language
$translations = // TODO load some file with $userLang here
Of course you should adjust this to your own project and environment. For translation files, you can use a plain PHP file that returns an array like such:
<?php
// en.php
return array(
'some.key' => 'Translation',
);
Then if you include that file, the return value of the include will be the array, so in the above code you could do:
$translations = include 'translations/'.$userLang.'.php';
You then have to output all your text through this $translations variable, like echo $translations['some.key'].

if you wanted to use cookies... in the lang files you would include an array of words or content to use.
<?php
if($_GET['language']){
$lang = (string)$_GET['language'];
setcookie("lang", $lang, time()+3600);
header('Location: '.$_SERVER['PHP_SELF']);
die();
}elseif(!isset($_COOKIE['lang'])){
$lang='en';
}else{$lang=$_COOKIE['lang'];}
switch($lang){
case "en":
include('./lang/en.php');
break;
case "fr":
include('./lang/fr.php');
break;
case "pol":
include('./lang/pol.php');
break;
default:
include('./lang/en.php');
break;
}
?>

Answer 3

you mean something along the lines of
if ($_GET['language']) {
include $_GET['language'] . ".php";
}
and then save the languages in a php-file with there name, or a function depending on what you want to do with it

maintain your current language in session.
When u change language call an ajax call Update the changed language into session and reload the page.
