在代码方面,这样的东西对你来说很棒.它必须基于用户的选择(从按钮或菜单中选择语言)或基于浏览语言(它不是最好的aPRouch).

的index.PHP

<?PHP

// verify the user's choice
if ($_POST[lang] == "en") 
{
    include_once("en_language.PHP");
}

if ($_POST[lang] == "pt") 
{
    include_once("pt_language.PHP");
}

// calling a lable in your page
echo LABEL_MENU;


// the rest of your file
...
?>

en_language.PHP

<?PHP
// ENGISH Language file
define('LABEL_MENU','Main Menu');

// the whole file with the labels of your system

?>

pt_language.PHP

<?PHP
// PORTUGUESE Language file
define('LABEL_MENU','Menu Principal');

// the whole file with the labels of your system

?>

补充

如果你希望使用数组类型,而不是使用define()的Constant值,但是我不知道什么比..

$arrays = array("MAIN_MENU" => "Main Menu","LEFT_MENU" => "Left Menu"); 
echo $arrays["MAIN_MENU"];
