最佳答案
在 PHP 中检测浏览器语言
我使用以下 PHP 脚本作为我的网站索引。
这个脚本应该包含一个特定的页面，这取决于浏览器的语言(自动检测)。
这个脚本并不适用于所有的浏览器，因此它总是包含任何检测到的语言的 index_en.php(问题的原因很可能是没有考虑某个 Accept-Language 头的问题)。
你能给我一个更有力的解决方案吗？
<?php
// Open session var
session_start();
// views: 1 = first visit; >1 = second visit
// Detect language from user agent browser
function lixlpixel_get_env_var($Var)
{
if(empty($GLOBALS[$Var]))
{
$GLOBALS[$Var]=(!empty($GLOBALS['_SERVER'][$Var]))?
$GLOBALS['_SERVER'][$Var] : (!empty($GLOBALS['HTTP_SERVER_VARS'][$Var])) ? $GLOBALS['HTTP_SERVER_VARS'][$Var]:'';
}
}
function lixlpixel_detect_lang()
{
// Detect HTTP_ACCEPT_LANGUAGE & HTTP_USER_AGENT.
lixlpixel_get_env_var('HTTP_ACCEPT_LANGUAGE');
lixlpixel_get_env_var('HTTP_USER_AGENT');
$_AL=strtolower($GLOBALS['HTTP_ACCEPT_LANGUAGE']);
$_UA=strtolower($GLOBALS['HTTP_USER_AGENT']);
// Try to detect Primary language if several languages are accepted.
foreach($GLOBALS['_LANG'] as $K)
