In this file (localization.php):

<?php
session_start();
header('Cache-control: private'); // IE 6 FIX

if(isSet($_GET['lang'])) {
    $lang = $_GET['lang'];

    // register the session and set the cookie
    $_SESSION['lang'] = $lang;
    setcookie("lang", $lang, time() + (3600 * 24 * 30));
}
else if(isSet($_SESSION['lang'])) {
    $lang = $_SESSION['lang'];
}
else if(isSet($_COOKIE['lang'])) {
    $lang = $_COOKIE['lang'];
}
else {
    $lang = 'en';
}

// use appropiate lang.xx.php file according to the value of the $lang
switch ($_SESSION['lang']) { //line 23
case 'en':
case 'es':
case 'zh-tw':
case 'zh-cn':
    $lang_file = 'lang.'.$_SESSION['lang'].'.php';
    break;

default:
    $lang_file = 'lang.en.php';
}
//localization helper function
function l($localization) {
    global $lang;
    return $lang[$localization];
}
    include_once 'languages/'.$lang_file;
?>

Ben aşağıdaki uyarı mesajı (localization.php) olsun:

Notice: Undefined index: lang in

D:\wamp\www\projects\alexchen\alexchen2.0\localization.php on line 23

Ama bu another similar file Ben bu uyarı alamadım:

<?php
session_start();
header('Cache-control: private'); // IE 6 FIX

if(isSet($_GET['lang'])) {
    $lang = $_GET['lang'];

    // register the session and set the cookie
    $_SESSION['lang'] = $lang;
    setcookie("lang", $lang, time() + (3600 * 24 * 30));
}
else if(isSet($_SESSION['lang'])) {
    $lang = $_SESSION['lang'];
}
else if(isSet($_COOKIE['lang'])) {
    $lang = $_COOKIE['lang'];
}
else {
    $lang = 'en';
}

// use appropiate lang.xx.php file according to the value of the $lang
switch ($lang) {
case 'en':
    $lang_file = 'lang.en.php';
    break;

case 'es':
    $lang_file = 'lang.es.php';
    break;

    $lang_file = 'lang.zh-tw.php';
    break;

case 'zh-cn':
    $lang_file = 'lang.zh-cn.php';
    break;

default:
    $lang_file = 'lang.en.php';
}

//translation helper function
function l($localization) {
    global $lang;
    return $lang[$localization];
}

    include_once 'languages/'.$lang_file;
?>

index.php:

    </head>
    <body id="home">
    <div id="header">
        <div class=

"container">

(Vb)

Ben onlar temelde aynı şeyi biliyorum ama neden ilk localization.php dosyadan uyarı alıyorum bir ben? Bunu nasıl düzeltebilirim?
