PHP access to browser information, guest language, guest operating system, guest IP address and visitor location

PHP gets the browser information. Get the guest language. Gets the guest operating system. Gets the guest IP address. Get a visitor's geographic location.

PHP access to browser information, access to the guest language: Simplified Chinese, Chinese, English. Get guest OS: Windows, MAC, Linux, Unix, BSD, other. Gets the guest IP address. Access to the location of visitors, the use of Sina Tencent interface.

One, PHP use Tencent IP sharing program to obtain IP location

<?php  
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, ten);     
curl_setopt ($ch, Curlopt_returntransfer, true); Get Data back    
$result = curl_exec ($ch);      
$result = mb_convert_encoding ($result, "Utf-8", "gb2312"); Code conversion, otherwise garbled   
curl_close ($ch);     
Preg_match ("@<span> (. *) </span></p> @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.     
?>

Second, php use Sina IP query interface to obtain IP location

<?php   
function Getiploc_sina ($queryIP) {      
$url = ' http://int.dpool.sina.com.cn/iplookup/iplookup.php? Format=json&ip= '. $queryIP;      
$ch = Curl_init ($url);       
curl_setopt ($ch, curlopt_encoding, ' UTF8 ');       
curl_setopt ($ch, Curlopt_timeout, 5);     
curl_setopt ($ch, Curlopt_returntransfer, true); Get Data back    
$location = curl_exec ($ch);      
$location = Json_decode ($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");
