Two methods for obtaining browser information and client location in PHP_PHP Tutorial

/**
* 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';

           $ip = explode(',',$_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

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");
?>
