PHP code to determine browser type, browser language and other information

//Determine the browser type
echo $_SERVER["HTTP_USER_AGENT"];
//Determine the browser language
echo $_SERVER["HTTP_ACCEPT_LANGUAGE"];
?>

The following are two complete examples to determine the browser type and browser language respectively. 1. Determine browser type

if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 8.0"))
echo "Internet Explorer 8.0";
else if(strpos($_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"];
?>

2. Determine browser language

$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 4); //Only take the first 4 digits, so that only the highest priority language is judged. If you take the first 5 digits, en and zh may occur, which affects the judgment.
if (preg_match("/zh-c/i", $lang))
echo "Simplified Chinese";
else if (preg_match("/zh/i", $lang))
echo "Traditional Chinese";
 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"];
/*@ http://bbs.it-home.org */
?>

From the above code, you can see that PHP determines the browser type mainly with the help of _SERVER["HTTP_USER_AGENT"], while analyzing the browser language uses _SERVER["HTTP_ACCEPT_LANGUAGE"].

In principle, the browser will always send some information including (browser type, language) when connecting to the server. We can use php global changes to $_SERVER, such as _SERVER["HTTP_USER_AGENT"] (browser type) and _SERVER["HTTP_ACCEPT_LANGUAGE"] (browser language) to obtain relevant information, and then use strpos or preg_match function to compare That's it.
