php判断浏览器和语言

判断浏览器语言:

<?php echo $_SERVER["HTTP_ACCEPT_LANGUAGE"]; ?>

判断浏览器语言的具体程序如下:

$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 4); //只取前4位，这样只判断最优先的语言。如果取前5位，可能出现en,zh的情况，影响判断。

if (preg_match("/zh-c/i", $lang))

echo "简体中文";

else if (preg_match("/zh/i", $lang))

echo "繁體中文";

else if (preg_match("/en/i", $lang))

echo "English";

else if (preg_match("/fr/i", $lang))

echo "French";

else if (preg_match("/de/i", $lang))

echo "German";

else if (preg_match("/jp/i", $lang))

echo "Japanese";

else if (preg_match("/ko/i", $lang))

echo "Korean";

else if (preg_match("/es/i", $lang))

echo "Spanish";

else if (preg_match("/sv/i", $lang))

echo "Swedish";

else echo $_SERVER["HTTP_ACCEPT_LANGUAGE"];

 if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 8.0"))  
echo "Internet Explorer 8.0"; // 这里可以写其他的执行命令  
else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 7.0"))  
echo "Internet Explorer 7.0";  
else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 6.0"))  
echo "Internet Explorer 6.0";  
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/3"))  
echo "Firefox 3";  
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/2"))  
echo "Firefox 2";  
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Chrome"))  
echo "Google Chrome";  
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Safari"))  
echo "Safari";  
else if(strpos($_SERVER["HTTP_USER_AGENT"],"Opera"))  
echo "Opera";  
else echo $_SERVER["HTTP_USER_AGENT"];
