mobile.php文件

当用户当手机访问该页面时,通过实现页面表单隐藏封装自动提交获取手机浏览器经纬度并post给服务器

        document.getElementById('lat').value = lat;

        document.getElementById('lng').value = lng;

    }

</script>

</head>

</html>

located.php文件

通过百度定位api进行解析定位

<?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);

?>
