function get_onlineip() {
$ch = curl_init('http://www.ip138.com/ip2city.asp');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$a = curl_exec($ch);
preg_match('/[(.*)]/', $a, $ip);
return $ip[1];
}
?>

方法2：使用$_SERVER['HTTP_X_FORWARDED_FOR']

function get_onlineip() {
$onlineip = '';
if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$onlineip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$onlineip = $_SERVER['REMOTE_ADDR'];
}
return $onlineip;
}
?>
