PHP sample code to determine region name information based on IP_PHP tutorial

Look at the code

Copy the code The code is as follows:

header("Content-type: text/ html; charset=utf-8");
function getIP(){
if (isset($_SERVER)) {
if (isset($_SERVER[HTTP_X_FORWARDED_FOR])) {
$realip = $_SERVER[HTTP_X_FORWARDED_FOR];
} elseif (isset($_SERVER[HTTP_CLIENT_IP])) {
$realip = $_SERVER[HTTP_CLIENT_IP];
} else {
$realip = $_SERVER[ REMOTE_ADDR];
}
} else {
if (getenv("HTTP_X_FORWARDED_FOR")) {
$realip = getenv( "HTTP_X_FORWARDED_FOR");
} elseif (getenv("HTTP_CLIENT_IP" )) {
$realip = getenv("HTTP_CLIENT_IP");
} else {
$realip = getenv("REMOTE_ADDR");
}
}
return $realip;
}

$ip = getIP();

// Use Sina interface to query regional information based on IP
/* $res0 = file_get_contents("http://int .dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=$ip");
$res0 = json_decode($res0);
print_r($res0);
echo "
"; */

// Use Taobao interface to query regional information based on IP
$res1 = file_get_contents("http://ip.taobao.com/service/getIpInfo. php?ip=$ip");
$res1 = json_decode($res1);
/* print_r($res1); */
