根据 ip查询位置

    echo '<br/>';
    $content = file_get_contents("http://api.map.baidu.com/location/ip?ak=7IZ6fgGEGohCrRKUE9Rj4TSQ&ip={$getIp}&coor=bd09ll");
    $json = json_decode($content);
    echo '<pre>';
    print_r($json);

    echo 'log:',$json->{'content'}->{'point'}->{'x'};//按层级关系提取经度数据
    echo '<br/>';
    echo 'lat:',$json->{'content'}->{'point'}->{'y'};//按层级关系提取纬度数据
    echo '<br/>';
    print $json->{'content'}->{'address'};//按层级关系提取address数据
