php實現手機定位功能的例項

最近在做通過定位手機使用者,進行訊息推送,經過分析最終做法如下

mobile.php檔案

當用戶當手機訪問該頁面時,通過實現頁面表單隱藏封裝自動提交獲取手機瀏覽器經緯度並post給伺服器

located.php檔案

通過百度定位api進行解析定位

<?php

header("Content-type:text/html; charset=utf8");

$url="http://api.map.baidu.com/geocoder/v2/?location=".$_POST["lat"].",".$_POST["lng"]."&ak=*****************************&coordtype=bd09ll&output=json";

$json = file_get_contents($url);

$arr = json_decode($json, true);

var_dump($arr);

?>
