Get IP address:
<code>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; } echo $ip = getIP(); </code>
//Sina interface queries the area information based on IP
<code>$res0 = file_get_contents("http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=$ip"); $res0 = json_decode($res0,true); print_r($res0); echo "<br/>"; </code>
//Taobao interface queries area information based on IP
<code>$res1 = file_get_contents("http://ip.taobao.com/service/getIpInfo.php?ip=$ip"); $res1 = json_decode($res1,true); print_r($res1); echo "<br/>";</code>
The above introduces PHP to obtain the IP address and the location of the IP address, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
