Php obtains qq user nickname and online status (instance analysis)

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 online QQ status by determining the length of the returned header.
The following code is used:
Copy codeThe Code is as follows:
<? Phpfunction get_qq_status ($ uin)
{
Error_reporting (0 );
$ F = file_get_contents ('HTTP: // wpa.qq.com/pa? P = 1: '. $ uin.': 4 ');
If (! $ F) return (true );
Foreach ($ http_response_header as $ val)
{
If (strpos ($ val, 'content-length ')! = False)
{
Return (intval (substr ($ val, 1000)> );
}
}
}

?>

The above is relatively simple. Here is a better
Copy codeThe Code is as follows:
<?
Function tphp_qq_online ($ uin)
{
$ Reques = "GET/pa? P = 1: ". $ uin.": 1 HTTP/1.1rn ";
$ Reques. = "Host: wpa. qq. comrn ";
$ Reques. = "User-Agent: PHP_QQ_SPYrnrn ";

If (! ($ Socket = socket_create (AF_INET, SOCK_STREAM, SOL_TCP) return (-1 );
If (! (Socket_connect ($ socket, "wpa.qq.com", 80) return (-1 );
If (! (Socket_write ($ socket, $ reques) return (-1 );
If (! ($ Respon = socket_read ($ socket, 1024, PHP_BINARY_READ) return (-1 );;
Socket_close ($ socket );

$ Field = explode ("rn", $ respon );
For ($ I = 0; $ I <count ($ field); $ I ++ ){
If (strncasecmp ($ field [$ I], "Location:", 9) = 0 ){
If (strpos ($ field [$ I], "online ")){
$ Ret = 1;
} Else if (strpos ($ field [$ I], "offline ")){
$ Ret = 0;
} Else {
$ Ret =-1;
} // If
Break;
} // If
} //

Return ($ ret );
}
/*}}}*/

 

Echo tphp_qq_online (561272831 );

?>

For example, qq user nickname and online status
Copy codeThe Code is as follows:
// Obtain QQ status
Function getQQState ($ qq ){
$ Url = 'HTTP: // wpa.qq.com/pa? P = 2: '. $ qq.': 41 & r = '. time ();
$ HeadInfo = get_headers ($ url, 1 );
$ Length = $ headInfo ['content-length'];
If ($ length = 1243 ){
Return true;
} Else {
Return false;
}
}
// Obtain QQ nickname
Function getQQNick ($ qq ){
$ Str = file_get_contents ('HTTP: // r.qzone.qq.com/cgi-bin/user/cgi_personal_card? Uin = '. $ qq );
$ Pattern = '/'. preg_quote ('"nickname ":"','/').'(.*?) '. Preg_quote (' ", ','/').'/I ';
Preg_match ($ pattern, $ str, $ result );
Return $ result [1];
}
// Obtain QQ name
Function getQQName ($ qq ){
// $ QqArr = include 'friendarr. php'; // pre-configured
// $ Username = $ qqArr [$ qq];
If (! $ Username ){
$ Username = getQQNick ($ qq );
}
Return $ username;
