Php functions for obtaining IE browser versions

To obtain browser information in php, you can directly use $ userAgentstrtolower ($ _ SERVER [& quot; HTTP_USER_AGENT & quot;]). then, you can judge your browser.

To obtain browser information in php, use $ userAgent = strtolower ($ _ SERVER [\ "HTTP_USER_AGENT \"]). then you can judge the version or model of your browser. I hope the following instances will help you.

Next I will introduce you to a php function that determines whether your browser is IE6. if "true" is returned, otherwise "false" is returned ".

The instance code is as follows:

1. Function isIE6 (){
2. $ UserAgent = strtolower ($ _ SERVER ["HTTP_USER_AGENT"]);
3. // Obtain the user's browser information from the HTTP_USER_AGENT field
4. If (ereg ("msie 6", $ userAgent) | ereg ("msie 5", $ userAgent )){
5. Return true;
6. }
7. Return false;
8. }

The complete instance code is as follows:

1. Function userBrowser (){
2. $ User_OSagent = $ _ SERVER ['http _ USER_AGENT '];
4. If (strpos ($ user_OSagent, "Maxthon") & strpos ($ user_OSagent, "MSIE ")){
5. $ Visitor_browser = "Maxthon (Microsoft IE )";
6. } Elseif (strpos ($ user_OSagent, "Maxthon 2.0 ")){
7. $ Visitor_browser = "Maxthon 2.0 ";
8. } Elseif (strpos ($ user_OSagent, "Maxthon ")){
9. $ Visitor_browser = "Maxthon ";
10. } Elseif (strpos ($ user_OSagent, "MSIE 9.0 ")){
11. $ Visitor_browser = "MSIE 9.0 ";
12. } Elseif (strpos ($ user_OSagent, "MSIE 8.0 ")){
13. $ Visitor_browser = "MSIE 8.0 ";
14. } Elseif (strpos ($ user_OSagent, "MSIE 7.0 ")){
15. $ Visitor_browser = "MSIE 7.0 ";
16. } Elseif (strpos ($ user_OSagent, "MSIE 6.0 ")){
17. $ Visitor_browser = "MSIE 6.0 ";
18. } Elseif (strpos ($ user_OSagent, "MSIE 5.5 ")){
19. $ Visitor_browser = "MSIE 5.5 ";
20. } Elseif (strpos ($ user_OSagent, "MSIE 5.0 ")){
21. $ Visitor_browser = "MSIE 5.0 ";
22. } Elseif (strpos ($ user_OSagent, "MSIE 4.01 ")){
23. $ Visitor_browser = "MSIE 4.01 ";
24. } Elseif (strpos ($ user_OSagent, "MSIE ")){
25. $ Visitor_browser = "higher MSIE version ";
26. } Elseif (strpos ($ user_OSagent, "NetCaptor ")){
27. $ Visitor_browser = "NetCaptor ";
28. } Elseif (strpos ($ user_OSagent, "Netscape ")){
29. $ Visitor_browser = "Netscape ";
30. } Elseif (strpos ($ user_OSagent, "Chrome ")){
31. $ Visitor_browser = "Chrome ";
32. } Elseif (strpos ($ user_OSagent, "Lynx ")){
33. $ Visitor_browser = "Lynx ";
34. } Elseif (strpos ($ user_OSagent, "Opera ")){
35. $ Visitor_browser = "Opera ";
36. } Elseif (strpos ($ user_OSagent, "Konqueror ")){
37. $ Visitor_browser = "Konqueror ";
38. } Elseif (strpos ($ user_OSagent, "Mozilla/5.0 ")){
39. $ Visitor_browser = "Mozilla ";
40. } Elseif (strpos ($ user_OSagent, "Firefox ")){
41. $ Visitor_browser = "Firefox ";
42. } Elseif (strpos ($ user_OSagent, "U ")){
43. $ Visitor_browser = "Firefox ";
44. } Else {
45. $ Visitor_browser = "others ";
46. }
47. Return $ visitor_browser;
48. }
