PHP查询ip所在地的几种方法(api实例)

 <p>请输入ip地址：<input type="text" name="ip" /></p>

 <p><input type="submit" value="查询"  /></p>

</form>

<?php

 //获取ip地址

 //$ip = $_SERVER['REMOTE_ADDR'];    //自动获取客户端的IP

 //ip对应的地区

 if(!empty($_POST['ip'])){

  $ip = $_POST['ip'];

  //接口地址,这样返回的是一个xml结果集，

  $str = file_get_contents("http://www.yodao.com/smartresult-xml/search.s?type=ip&q=".$ip);

  //这里要得到里面的地址信息，提取xml方法有很多，我用的是正则。

  preg_match_all( "/<location>(.*?)</location>/",$str,$addr1);

  //最终结果，如图2;

  $addr = $ip."=>".$addr1[1][0];

  echo $addr;

 }

?>

list($addr1,$addr2)=$qqwry->q('127.0.0.1');
$addr1=iconv('GB2312','UTF-8',$addr1);
$addr2=iconv('GB2312','UTF-8',$addr2);
echo $addr1,'|',$addr2," ";

$arr=$qqwry->q('222.216.47.4');
$arr[0]=iconv('GB2312','UTF-8',$arr[0]);
$arr[1]=iconv('GB2312','UTF-8',$arr[1]);
echo $arr[0],'|',$arr[1]," ";

$arr[1]=iconv('GB2312','UTF-8',$arr[1]);
