Select portuguese text (default)

[PF2G]

Hi,
i'm working on a website where i select some text from DB according to the language selected:

Here's where i define the language (where default = 'pt'):

<?php
//array
$lang = array('pt', 'en');

//iniciar sessao -> array
session_start();

//verificar var lang no url -> pagina.php?lang=pt
if(isset($_GET['lang']) && in_array($_GET['lang'], $lang))
{
    $_SESSION['lang'] = $_GET['lang'];
}
else
{
    $_SESSION['lang'] = 'pt';
}

//incluir a linguagem
if(isset($_SESSION['lang']) && in_array($_SESSION['lang'], $lang))
{
    require_once 'lang_'.$_SESSION['lang'].'.php';
}
?>

And here is where i'm selecting the text:

<?php
ob_start();

include 'common.php';
include 'db_connect.php';

if (isset($_GET['lang']))
{
    $sel_lang="SELECT * FROM content_lang WHERE lang='".$_GET['lang']."'";
    $language=mysql_query($sel_lang, $connect);
    $row_lang=mysql_fetch_assoc($language);

    $sel_text="SELECT * FROM content_lang WHERE titulo='Family Office' AND lang='".$row_lang['lang']."'";
    $text=mysql_query($sel_text, $connect);
    $row_text=mysql_fetch_assoc($text);
?> 

<span class="fontchange"> <?php echo $row_text['titulo'];?> </span>
<?php echo $row_text['descricao']; ?>

<?php
    $content=ob_get_contents();
    ob_clean();
    $title="Familly Office";
    $image="familyoffice2.png";
    include 'include/master.php';
}
?>

I want to say that if lang = default the text is portuguese (pt).

Can someone help me?

Thank you,
PF2G

You need to include the first snippet in every page.

I don't understand why you're duplicating code in the second snippet. You should already have your language in the $_SESSION['lang'] variable. If you've included the first snippet.
