1. Get browser information, PHP class to obtain guest operating system: windows, mac, linux, unix, bsd, other, and visitor IP address and other information

Copy code The code is as follows:

/**
* Classes for obtaining visitor information: language, browser, operating system, ip, geographical location, isp.
* Usage:
* $obj = new guest_info;
* $obj->getlang(); //Get guest language: simplified Chinese, traditional Chinese, english.
* $obj->getbrowser(); //Get the visitor's browser: msie, firefox, chrome, safari, opera, other.
* $obj->getos(); //Get the guest operating system: windows, mac, linux, unix, bsd, other.
* $obj->getip(); //Get the visitor’s IP address.
* $obj->getadd(); //Get the visitor’s geographical location and use baidu hidden interface.
* $obj->getisp(); //Get the visitor isp and use baidu to hide the interface.
*/
class guest_info{
function getlang() {
$lang = substr($_server['http_accept_language'], 0, 4);
//Use substr() to intercept String, starting from position 0, intercepting 4 characters
if (preg_match('/zh-c/i',$lang)) {
//preg_match() regular expression matching function
$ lang = 'Simplified Chinese';
}
elseif (preg_match('/zh/i',$lang)) {

           $lang = 'english';
if (preg_match('/msie/i',$browser)) {
             $browser = 'msie';                                                             🎜>            $browser = 'firefox';
elseif (preg_match('/safari/i',$browser)) {
$browser = 'safari';
elseif (preg_match('/opera/i',$browser)) {
                $browser = 'opera';                                               > }
function getos() {
$os = $_server['http_user_agent'];
if (preg_match('/win/i',$os)) {
$os = 'windows';
}
elseif (preg_match('/mac/i',$os)) {
🎜>             $os = 'linux';                                                   🎜> elseif (preg_match('/bsd/i',$os)) {
                                                       🎜 >           return $os; Then empty() returns false.
           $ip = explode(',',$_server['http_client_ip']);                                     (',',$_server['http_x_forwarded_for']);                                   ['remote_addr']);
      }
}

$obj = new guest_info;
echo $obj->getlang(); //Get guest language: simplified Chinese, traditional Chinese, english.
echo $obj->getbrowser(); //Get the visitor's browser: msie, firefox, chrome, safari, opera, other.
echo $obj->getos(); //Get the guest operating system: windows, mac, linux, unix, bsd, other.
echo $obj->getip(); //Get the visitor’s IP address.
?>

2. PHP uses Tencent IP sharing plan to obtain IP location

Copy code

The code is as follows:

function getiploc_qq($queryip){

$ url = 'http://ip.qq.com/cgi-bin/searchip?searchip1='.$queryip;
$ch = curl_init($url);
curl_setopt($ch,curlopt_encoding,'gb2312 '); curl_setopt($ch, curlopt_timeout, 10); curl_setopt($ch, curlopt_returntransfer, true); // Get data and return it $result = curl_exec($ch); $ result = mb_convert_encoding($result, "utf-8", "gb2312"); // Encoding conversion, otherwise garbled code
curl_close($ch);

preg_match("@(.*)< ;/span>
@iu",$result,$iparray);
$loc = $iparray[1];
return $loc;
}
//Use
echo getiploc_qq("183.37.209.57"); //You can get the address location of the ip address.
?>

3. PHP uses Sina IP query interface to obtain IP geographical location

Copy code
The code is as follows:

function getiploc_sina($queryip){

$ url = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip='.$queryip;
$ch = curl_init($url);
curl_setopt($ ch,curlopt_encoding,'utf8'); ); $location = json_decode($location); curl_close($ch); $loc = ""; if($location===false) return "";
if (empty($location->desc)) {
$loc = $location->province.$location->city.$location->district.$location->isp;
}else{ $loc = $location->desc;
}
return $loc;
}
echo getiploc_sina("183.37.209.57");
?>
