php获取指定(访客)IP所有信息（地址、邮政编码、国家、经纬度等）的方法

<?php  
function getIpInfo($ip,$timeout=15) {  
  if(!function_exists('curl_init') or !function_exists('simplexml_load_string')) return false;  
  $ch = curl_init("http://ipinfodb.com/ip_query2.php?ip={$ip}&timezone=true");

      CURLOPT_RETURNTRANSFER => true,  
    );  
  curl_setopt_array($ch,$options);  
  $res = curl_exec($ch);  
  curl_close($ch);  
  
  if($xml = simplexml_load_string($res)) {  
    $return = array();  
    foreach ($xml->Location->children() as $key=>$item) {  
      $return[$key] = strtolower($item);  
    }  
    return $return;  
  } else {  
    return false;  
  }

$current_Ip_Info = getIpInfo('119.7.8.255');
