用户Ip地址和百度地图api接口获取用户地理位置(经纬度坐标,城市)
<?php//获取用户ip(外网ip 服务器上可以获取用户外网Ip 本机ip地址只能获取127.0.0.1)function getip(){ if(!empty($_SERVER["HTTP_CLIENT_IP"])){ $cip = $_SERVER["HTTP_CLIENT_IP"]; } else if(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){ $cip = $_SERVER["HTTP_X_FORWARDED_FOR"]; } else if(!empty($_SERVER["REMOTE_ADDR"])){ $cip = $_SERVER["REMOTE_ADDR"]; } else{ $cip = ''; } preg_match("/[\d\.]{7,15}/", $cip, $cips); $cip = isset($cips[0]) ? $cips[0] : 'unknown'; unset($cips); return $cip;}$ip=getip();//根据百度地图api得到用户Ip地理经纬度和城市$url = "http://api.map.baidu.com/location/ip?ak=omi69HPHpl5luMtrjFzXn9df&ip=$ip&coor=bd09ll";$ch = curl_init();curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);$output = curl_exec($ch);if(curl_errno($ch)){ echo 'CURL ERROR Code: '.curl_errno($ch).', reason: '.curl_error($ch);}curl_close($ch);$info = json_decode($output, true);if($info['status'] == "0"){ $lotx = $info['content']['point']['y']; $loty = $info['content']['point']['x']; $citytemp = $info['content']['address_detail']['city']; $keywords = explode("市",$citytemp); $city = $keywords[0];}else{ $lotx = "34.2597"; $loty = "108.9471"; $city = "西安";}var_dump($lotx);//x坐标 纬度var_dump($loty);//y坐标 经度var_dump($city);//用户Ip所在城市 |
