  1. //Determine the browser type

  3. //Determine the browser language
  4. echo $_SERVER["HTTP_ACCEPT_LANGUAGE"];
  5. ?>
Copy the code

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

  1. if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 8.0"))
  2. echo "Internet Explorer 8.0";
  3. else if(strpos($_SERVER["HTTP_USER_AGENT"] ,"MSIE 7.0"))
  4. echo "Internet Explorer 7.0";
  5. else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 6.0"))
  6. echo "Internet Explorer 6.0";
  7. else if(strpos($ _SERVER["HTTP_USER_AGENT"],"Firefox/3"))
  8. echo "Firefox 3";
  9. else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/2"))
  10. echo "Firefox 2";
  11. else if(strpos($_SERVER["HTTP_USER_AGENT"],"Chrome"))
  12. echo "Google Chrome";
  13. else if(strpos($_SERVER["HTTP_USER_AGENT"],"Safari"))
  14. echo "Safari";
  15. else if(strpos($_SERVER["HTTP_USER_AGENT"],"Opera"))
  16. echo "Opera";
  17. else echo $_SERVER["HTTP_USER_AGENT"];
  18. ?>
Copy code

2. Determine browser language

  1. $lang = substr($_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.
  2. if (preg_match("/zh-c/i", $lang))
  3. echo "Simplified Chinese";
  4. else if (preg_match("/zh/i", $lang))
  5. echo "Traditional Chinese";
  6. else if (preg_match("/en/i", $lang))
  7. echo "English";
  8. else if (preg_match("/fr/i", $lang))
  9. echo "French";
  10. else if (preg_match ("/de/i", $lang))
  11. echo "German";
  12. else if (preg_match("/jp/i", $lang))
  13. echo "Japanese";
  14. else if (preg_match("/ko /i", $lang))
  15. echo "Korean";
  16. else if (preg_match("/es/i", $lang))
  17. echo "Spanish";
  18. else if (preg_match("/sv/i", $lang))
  19. echo "Swedish";
  20. else echo $_SERVER["HTTP_ACCEPT_LANGUAGE"];
  21. /*@ http://bbs.it-home.org */
  22. ?>
Copy code

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.
