需要顯示評論者的地域屬性,這個特點可以通過記錄會員IP的地理信息來實現,下面提供一個淘寶IP地址查詢類，簡化相關的信息查詢，大家參考使用吧
淘寶公司提供了一個很好用的IP地理信息查詢接口。在這裡:http://ip.taobao.com/ 以下這個taobaoIPQuery類將極大的簡化相關的信息查詢。 代碼如下: <?php class taobaoIPQuery { private $m_ip; private $m_content; public function __construct($ip) { if (isset($ip)) { $this->m_ip = $ip; } else { $this->m_ip = ""; } if (!empty($this->m_ip)) { $url_handle = curl_init(); curl_setopt($url_handle, CURLOPT_URL, "http://ip.taobao.com/service/getIpInfo.php?ip=" . $this->m_ip); curl_setopt($url_handle, CURLOPT_RETURNTRANSFER, true); $this->m_content = curl_exec($url_handle); curl_close($url_handle); if ($this->m_content) { $this->m_content = json_decode($this->m_content); if ($this->m_content->{'code'} == 1) { exit("query error!"); } } else { exit("curl error!"); } } else { exit("ip address must be not empty!"); } } public function get_region() { return $this->m_content->{'data'}->{'region'}; } public function get_isp() { return $this->m_content->{'data'}->{'isp'}; } public function get_country() { return $this->m_content->{'data'}->{'country'}; } public function get_city() { return $this->m_content->{'data'}->{'city'}; } } 調用很簡單 代碼如下: $ip = $_SERVER["REMOTE_ADDR"]; $ipquery = new taobaoIPQuery($ip); $region = $ipquery->get_region(); $country = $ipquery->get_country(); $city = $ipquery->get_city();
