如何用PHP设置3种语言？

Question

I try to insert a third language in an existing page wich is already in french and english. I'm kind of beginner with php.

Here's the code:

<?php
$lang = (isset($_GET['lang']) && $_GET['lang'] == 'en') ? 'en' : 'fr' ;
$langParam = ($lang == 'en') ? '&lang=en' : '';
$typeTerms = array(


'fr' => array(
    'WINES' => 'vins',
    'BEERS' => 'Bières',
    'MALTCOOLER' => 'boisson à base de malt',
    'CIDER' => 'cidres',
    'ALCOHOLFREE' => 'produits sans alcool<br/>et à faible teneur en alcool',
    'OTHERS' => 'autres'
),

'en' => array(
    'WINES' => 'Wines',
    'BEERS' => 'Beers',
    'MALTCOOLER' => 'Malt Based Cooler',
    'CIDER' => 'Cider',
    'ALCOHOLFREE' => 'Alcohol-free and low-alcoholic products',
    'OTHERS' => 'Others'
)
);




?>

And I want to insert this array, and make it work!

'zh' => array(
    'WINES' => '葡萄酒',
    'BEERS' => '啤酒',
    'MALTCOOLER' => '麦芽果酒',
    'CIDER' => '苹果酒',
    'ALCOHOLFREE' => '无酒精及低度酒精饮料',
    'OTHERS' => '其它'
)

Thanks!

Just

 $lang = isset($_GET['lang'])?$_GET['lang']:"en";
 if(!in_array($lang,array("en","fr","zh"))) $lang = "en";

To add a new one:

    $typeTerms['zh'] = array(
        'WINES' => '葡萄酒',
        'BEERS' => '啤酒',
        'MALTCOOLER' => '麦芽果酒',
        'CIDER' => '苹果酒',
        'ALCOHOLFREE' => '无酒精及低度酒精饮料',
        'OTHERS' => '其它'
    );
