Code for PHP to determine browser type, browser language, and other information

Determine browser type echo $_server["Http_user_agent"]; Determine the browser language echo $_server["Http_accept_language"]; ?> Copy Code Here are two complete examples to determine browser type, browser language, respectively. 1. Determine browser type if (Strpos ($_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"]; ?> Copy Code 2. determine the browser language $lang = substr ($_server[' http_accept_language '), 0, 4); Take only the first 4 digits, so that only the most preferred language is judged. If take the first 5 bits, may appear en,zh situation, influence 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 "中文版"; 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 */ ?> Copy Code From the above code, you can see PHP judging browser type, mainly with the help of _server["Http_user_agent", and the analysis of the browser language is the use of _server["Http_accept_language"]. In principle, the browser will always send some information including (browser type, language) class when connecting with the server. We can use PHP global change $_server, such as _server["Http_user_agent" (browser type) and _server["Http_accept_language"] (browser language) to obtain relevant information, Then you can compare it with Strpos or Preg_match functions. Well, it's about PHP judging browser type, browser language, and so on.
