网站常用的一些东西

1. 屏蔽中文浏览器

JS版本：
<script language=”javascript”>
<!–
var t=navigator.userLanguage
if (t==”zh-cn” || t==”zh-tw” || t==”zh-hk” || t==”zh-mo”)
{
location.replace(“http://www.xxxx.cn/”);
}
else
{
location.replace(“http://www.xxx.com/”);
}
–>
</script>

PHP版本
<?php
$b_lang = ”;
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 4);
if (preg_match(“/zh-c/i”, $lang))
$b_lang = ‘sc’;
else if (preg_match(“/zh/i”, $lang))
$b_lang = ‘tc’;
else
$b_lang = ‘ot’;
if ($b_lang == ‘sc’  ||  $b_lang == ‘tc’  ){
echo “<script language=’javascript’>”;
echo ” location=’/welcome.html’;”;
echo “</script>”;
}
?>
