problem with array - multilingual page

Posted on 16th Feb 2014 by admin

this is my test page :
Code: <?php
if(isset($_GET['lang'])) {
if($_GET['lang'] == "en") {
require_once("languages/lang-en.php");
}
elseif($_GET['lang'] == "fr") {
require_once("languages/lang-fr.php");
}
elseif($_GET['lang'] == "ar") {
require_once("languages/lang-ar.php");
}
} else {
require_once("languages/lang-fr.php");
}
?>
<html>
<head>
<title><?php echo $lang['title']; ?></title>
</head>
<body>
<div id="content">
<h1><?php $lang['title']; ?></h1>
<?php $lang['content']; ?>
<br/>
</div>
<div id="footer">
<?php $lang['footer']; ?>
</div>
</body>
</html>

and here is my included file :
Code: <?php
// english version
$lang = array();

$lang['title'] = "Welcome to My site !";
$lang['content'] = "<p>Well this is my first time setting up a multilingual website, i hope it works.</p>";
$lang['footer'] = "All rights reserved for UML (C) ".date("Y", time());
$lang['error'] = "Sorry, you cannot add words unless you're logged in !";
?>
the problem is that page displays the head title only !!!!
what should i do???
