How to get mobile phone location in php

Recently, I have been working on locating mobile phone users and pushing messages. After analysis, the final method is The following

mobile.php file (recommended learning: PHP programming from entry to proficiency)

When the user accesses this page on a mobile phone When the page form is hidden and encapsulated, it is automatically submitted to obtain the longitude and latitude of the mobile browser and post it to the server

<html>

<meta charset="utf8">

<head>

<form name="form1" action="http://test.nwee.cc/ken/baidulocated.php" method="post">

<input type="text" name="lat" id="lat" style="display:none">

<input type="text" name="lng" id="lng" style="display:none">

</form>

<script type="text/javascript">

    var position_option = {

        enableHighAccuracy: true,

        maximumAge: Infinity,

        timeout: 100000

    }; 

    var lat;

    var lng;

    if(navigator.geolocation){

        navigator.geolocation.getCurrentPosition(getPositionSuccess, getPositionError, position_option);

    }else{

        alert(&#39;Geolocation is not supported by this browser.&#39;);

    }

    function getPositionSuccess(position) {

        lat = position.coords.latitude;

        lng = position.coords.longitude;

        //alert(&#39;您所在的位置： 纬度&#39; + lat + &#39;，经度&#39; + lng);

fillForm(); 

//填充表单

document.form1.submit();

//post数据到服务器

    }

    function getPositionError(error) {

        switch (error.code) {

            case error.TIMEOUT:

            alert(&#39;The request to get user location timed out.&#39;);break;

            case error.PERMISSION_DENIED:

            alert(&#39;User denied the request for Geolocation.&#39;);break;

            case error.POSITION_UNAVAILABLE:

            alert(&#39;Location information is unavailable.&#39;);break;

            default:

            alert(&#39;An unknown error occurred.&#39;);

        }

    }

    function fillForm(){

        document.getElementById(&#39;lat&#39;).value = lat;

        document.getElementById(&#39;lng&#39;).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);

?>
