Php obtains qq user nicknames and online status instances

QQ returns different images to indicate online or offline, and the icons also change. since the images are different, the Content-Length in the returned HTTP header must be different, A color image must be larger than a dark image in the same way. Therefore, you can find the middle value of a color image or a dark image, you can obtain the QQ online status by determining the length of the returned header. the following code is used:

2. Function get_qq_status ($ uin)
3. {
4. Error_reporting (0 );
5. $ F = file_get_contents ('http: // wpa.qq.com/pa? P = 1: '. $ uin.': 4 ');
6. If (! $ F) return (true );
7. Foreach ($ http_response_header as $ val)
8. {
9. If (strpos ($ val, 'Content-length ')! = False)
10. {
11. Return (intval (substr ($ val, 1000)> );
12. }
13. }
14. }
15. ?>

The above is relatively simple. the code below is better:

2. Function tphp_qq_online ($ uin)
3. {
4. $ Reques = "GET/pa? P = 1: ". $ uin.": 1 HTTP/1.1rn ";
5. $ Reques. = "Host: wpa. qq. comrn ";
6. $ Reques. = "User-Agent: PHP_QQ_SPYrnrn ";
8. If (! ($ Socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP) return (-1 );
9. If (! (Socket_connect ($ socket, "wpa.qq.com", 80) return (-1 );
10. If (! (Socket_write ($ socket, $ reques) return (-1 );
11. If (! ($ Respon = socket_read ($ socket, 1024, PHP_BINARY_READ) return (-1 );;
12. Socket_close ($ socket );
14. $ Field = explode ("rn", $ respon );
15. For ($ I = 0; $ I
16. If (strncasecmp ($ field [$ I], "Location:", 9) = 0 ){
17. If (strpos ($ field [$ I], "online ")){
18. $ Ret = 1;
19. } Else if (strpos ($ field [$ I], "offline ")){
20. $ Ret = 0;
21. } Else {
22. $ Ret =-1;
23. } // If
24. Break;
25. } // If
26. } //
28. Return ($ ret );
29. }
30. /*}}}*/
31. Echo tphp_qq_online (561272831 );
32. ?>

For example, qq user nickname and online status. the code is as follows:

1. // Obtain QQ status
2. Function getQQState ($ qq ){
3. $ Url = 'http: // wpa.qq.com/pa? P = 2: '. $ qq.': 41 & r = '. time ();
4. $ HeadInfo = get_headers ($ url, 1 );
5. $ Length = $ headInfo ['content-length'];
6. If ($ length = 1243 ){
7. Return true;
8. } Else {
9. Return false;
10. }
11. }
12. // Obtain QQ nickname
13. Function getQQNick ($ qq ){
14. $ Str = file_get_contents ('http: // r.qzone.qq.com/cgi-bin/user/cgi_personal_card? Uin = '. $ qq );
15. $ Pattern = '/'. preg_quote ('"nickname ":"','/').'(.*?) '. Preg_quote (' ", ','/').'/I ';
16. Preg_match ($ pattern, $ str, $ result );
17. Return $ result [1];
18. }
19. // Obtain QQ name
20. Function getQQName ($ qq ){
21. // $ QqArr = include 'friendarr. php'; // pre-configured
22. // $ Username = $ qqArr [$ qq];
23. If (! $ Username ){
24. $ Username = getQQNick ($ qq );
25. }
26. Return $ username;
27. }
