PHP实现IP自动判断城市效能

$ip='183.16.198.102';<br />$json=file_get_contents('http://ip.taobao.com/service/getIpInfo.php?ip='.$ip);<br />$arr=json_decode($json);<br />echo $arr->data->country;	//国家<br />echo $arr->data->area;	//区域<br />echo $arr->data->region;	//省份<br />echo $arr->data->city;	//城市<br />echo $arr->data->isp;	//运营商

header("Content-type: text/html; charset=utf-8");<br />$ip=$_SERVER["REMOTE_ADDR"];<br />$json=file_get_contents('http://ip.taobao.com/service/getIpInfo.php?ip='.$ip);<br />$arr=json_decode($json);<br />echo 'IP:'.$ip;<br />echo '<br>城市:'.$arr->data->city;

<br />$json=file_get_contents('http://ip.taobao.com/service/getIpInfo.php?ip='.$ip);<br />$arr=json_decode($json);<br />echo "<pre class="brush:php;toolbar:false">";<br />print_r($arr);<br />
