代码如下:
PHP
/**
* 获取客户端IP
* @param integer $type 返回类型 0:string,1:long
* @return string|long
*/
function getClientIp($type = 0) {
$ip = NULL;
if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$arr = explode(',',$_SERVER['HTTP_X_FORWARDED_FOR']);
$pos = array_search('unknown',$arr);
if(false !== $pos) unset($arr[$pos]);
$ip = trim($arr[0]);
}elseif (isset($_SERVER['HTTP_CLIENT_IP'])) {
$ip = $_SERVER['HTTP_CLIENT_IP'];
}elseif (isset($_SERVER['REMOTE_ADDR'])) {
$ip = $_SERVER['REMOTE_ADDR'];
}
$long = sprintf("%u",ip2long($ip));
$ip = $long ? array($ip,$long) : array('0.0.0.0',0);
return $ip[$type];
}
/**
* 获取IP信息
* @param string|long $ip IP地址
* @return array
*/
function getIpInfo($ip)
{
if (is_long($ip)) {
$ip = long2ip($ip);
}
$api = 'http://ip.taobao.com/service/getIpInfo.PHP';
$ret = file_get_contents($api . '?ip=' . $ip);
$ret = json_decode($ret,true);
if ($ret['code'] == 0) {
return $ret['data'];
}
return array();
}
