This article mainly introduces the method of PHP to obtain IP detailed address based on Sina IP library, involving PHP regular, curl and coding conversion related operation skills. Friends in need can refer to the following
The details are as follows:
<?php class Tool{ /** * 获取IP的归属地( 新浪IP库 ) * * @param $ip String IP地址:112.65.102.16 * @return Array */ static public function getIpCity($ip) { $ip = preg_replace("/\s/","",preg_replace("/\r\n/","",$ip)); $link = "http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=js&ip=".$ip."&t=".time(); $ipJson = self::httpCurl($link); preg_match("/\"country\":\"(.*)\"/Uis",$ipJson, $match1); preg_match("/\"province\":\"(.*)\"/Uis",$ipJson, $match2); preg_match("/\"city\":\"(.*)\"/Uis",$ipJson, $match3); return array( 'country'=>self::ucode2zh($match1[1]), // 国家 'province'=>self::ucode2zh($match2[1]), // 省 'city'=>self::ucode2zh($match3[1]) // 城市 ); } /** * Curl方式获取信息 */ static public function httpCurl($url) { $curl_handle = curl_init(); curl_setopt($curl_handle, CURLOPT_URL, $url); curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT,2); curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER,1); curl_setopt($curl_handle, CURLOPT_FAILONERROR,1); $file_content = curl_exec($curl_handle); curl_close($curl_handle); return $file_content; } /** * 将unicode编码转化为中文,转化失败返回原字符串 * * @param $code String unicode编码 * @return String */ static public function ucode2zh($code) { $temp = explode('\u',$code); $rslt = array(); array_shift($temp); foreach($temp as $k => $v) { $v = hexdec($v); $rslt[] = '' . $v . ';'; } $r = implode('',$rslt); return empty($r) ? $code : $r; } }
Get IP address class usage example
<?php $ipStr = Tool::getIpCity('112.65.102.16'); print_r($ipStr);
Return results
Array ( [country] => 中国 [province] => 上海 [city] => 上海 )
