分开操作

 

/** * 调用淘宝地址库 * */function ip_taobao($ip){    $urlTaobao = 'http://ip.taobao.com/service/getIpInfo.php?ip='.$ip;    $json = file_get_contents($urlTaobao);    $jsonDecode = json_decode($json);    $data['country'] = $jsonDecode->data->country;    $data['province'] = $jsonDecode->data->region;    $data['city'] = $jsonDecode->data->city;    $data['isp'] = $jsonDecode->data->isp;    return $data;}/** * 调用新浪地址库 * */function ip_sina($ip){    $data = '';    $urlSina = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip='.$ip;    $json = file_get_contents($urlSina);    $jsonDecode = json_decode($json);    if($jsonDecode == '-2'){        $data['error'] = '未分配或者内网IP';    }else{        $data['country'] = $jsonDecode->country;        $data['province'] = $jsonDecode->province;        $data['city'] = $jsonDecode->city;        $data['isp'] = $jsonDecode->isp;        $data['district'] = $jsonDecode->district;    }    return $data;}

　调用 

/**     * 返回ip所在位置     * */    public function ip_address($ip=''){       if (empty($ip)) $ip = request()->ip();        $info = Model('site')->info();        if($info['ip_library'] ==1){            $arr= ip_taobao($ip);        }else{            $arr= ip_sina($ip);        }        $address = implode(' ',$arr);        return $address;    }

 

新的用法

$ip = Request()->ip();        $ip_info = ip_sina($ip);        if($ip_info['country']!='未分配或者内网IP'){            $address = implode(' ',$ip_info);        }else{            $address = '未分配或者内网IP';        }        print_r($address);

 

最完美的地址库

 

 

/** * 调用淘宝地址库 * */function ip_taobao($ip){    //$ip = '113.87.131.159';    $opt = [        'http'=>[            'method'=>'GET',            'timeout'=> 5        ]    ];    $context = stream_context_create($opt);    $urlTaobao = 'http://ip.taobao.com/service/getIpInfo.php?ip='.$ip;    $json = @file_get_contents($urlTaobao,false,$context);    $jsonDecode = json_decode($json);    if($jsonDecode){        $data['country'] = $jsonDecode->data->country;        $data['province'] = $jsonDecode->data->region;        $data['city'] = $jsonDecode->data->city;        $data['isp'] = $jsonDecode->data->isp;    }else{        $data['country'] = '无法连接网络';    }    return $data;}/** * 调用新浪地址库 * */function ip_sina($ip){    //$ip = '113.87.131.159';    $opt = [        'http'=>[            'method'=>'GET',            'timeout'=> 5        ]    ];    $context = stream_context_create($opt);    $data = '';    $urlSina = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip='.$ip;    $json = @file_get_contents($urlSina,false,$context);    $jsonDecode = json_decode($json);    if($jsonDecode){        if($jsonDecode == '-2'){            $data['country'] = '未分配或者内网IP';        }else{            $data['country'] = $jsonDecode->country;            $data['province'] = $jsonDecode->province;            $data['city'] = $jsonDecode->city;            $data['isp'] = $jsonDecode->isp;            $data['district'] = $jsonDecode->district;        }    }else{        $data['country'] = '无法连接网络';    }    return $data;}
