【PHP】新浪、淘宝的地区 API调用

/推荐使用新浪的：
$ch = curl_init();
$url = "http://ip.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=202.102.3.141";    //测试202.102.3.141 江苏省常州市
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT,10); 

$sourceInfo_sina = json_decode(curl_exec($ch)); 

//淘宝(经实际使用发现，数据老旧，地区不准)：
$ch = curl_init();
$url = "http://ip.taobao.com/service/getIpInfo.php?ip=202.102.3.141";    //测试202.102.3.141 江苏省常州市
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT,10); 

$sourceInfo_taobao = json_decode(curl_exec($ch));
