PHP实现根据浏览器跳转不同语言页面代码

复制代码 代码如下:
<?php
$lan = $_SERVER['HTTP_ACCEPT_LANGUAGE'];   //获取浏览器语言版本
if (preg_match("/[zh]{2}\-[hk]{2}/", $lan) || preg_match("/[zh]{2}\-[tw]{2}/", $lan)) {
    $url = 'hk/index.php';
    header("location: " . $url);
} elseif (preg_match("/(?i)^[en]/", $lan)) {
    $url = 'en/index.php';
    header("location: " . $url);
} elseif (preg_match("/[zh]{2}\-[cn]{2}/", $lan)) {
    $url = 'cn/index.php';
    header("location: " . $url);
} else { 
    $url = 'en/index.php';
    header("location: " . $url);
}
?>
