Question

首先，请为我的英语道歉。

嗨！我需要用PHP打印当前用户的地址，我有这个小脚本：

<?
  function getaddress($lat,$lng)
  {
     $url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng='.trim($lat).','.trim($lng).'&sensor=false';
     $json = @file_get_contents($url);
     $data=json_decode($json);
     $status = $data->status;
     if($status=="OK")
     {
       return $data->results[0]->formatted_address;
     }
     else
     {
       return false;
     }
  }
?>

<?php
  $lat= 21.884766199999998; //latitude
  $lng= -102.2996459; //longitude
  $address= getaddress($lat,$lng);
  if($address)
  {
    echo $address;
  }
  else
  {
    echo "Not found";
  }
?>

当然可行，但我不知道如何将$ lat和$ long变量更改为当前用户位置。

用几句话说;我如何将当前用户lat和long位置传递给PHP变量以使这个脚本有效？

Answer 1

<html>
<body>
<p id="demo">Click the button to get your coordinates:</p>
<button onclick="getLocation()">Try It</button>
<script>
var x=document.getElementById("demo");
function getLocation()
  {
  if (navigator.geolocation)
    {
    navigator.geolocation.getCurrentPosition(showPosition);
    }
  else{x.innerHTML="Geolocation is not supported by this browser.";}
  }
function showPosition(position)
  {
  x.innerHTML="Latitude: " + position.coords.latitude + 
  "<br>Longitude: " + position.coords.longitude;    
  }
</script>
</body>
</html>

这是一个基于JavaScript的搜索。你可以在HTML浏览器中尝试它并将lat long传递给php脚本。

如果它可以帮助你，或者你可以告诉我，我也有其他方法。

Answer 2

您需要使用JavaScript或其他Google API来获取此功能。哪个你可以放置lat＆amp;在一个单独的隐藏字段中，然后从隐藏的字段中分配给您的php变量。

以下是使用html 5和java-script

获取此示例的示例脚本

<script>
var x = document.getElementById("demo");
function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
    } else {
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}
function showPosition(position) {
    x.innerHTML = "Latitude: " + position.coords.latitude + 
    "<br>Longitude: " + position.coords.longitude; 
}
</script>

这是另一个使用Google地理位置API的脚本

    <!DOCTYPE html>
<html>
  <head>
    <title>Geolocation</title>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
    <meta charset="utf-8">
    <style>
      /* Always set the map height explicitly to define the size of the div
       * element that contains the map. */
      #map {
        height: 100%;
      }
      /* Optional: Makes the sample page fill the window. */
      html, body {
        height: 100%;
        margin: 0;
        padding: 0;
      }
    </style>
  </head>
  <body>
    <div id="map"></div>
    <script>
      // Note: This example requires that you consent to location sharing when
      // prompted by your browser. If you see the error "The Geolocation service
      // failed.", it means you probably did not give permission for the browser to
      // locate you.
      var map, infoWindow;
      function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
          center: {lat: -34.397, lng: 150.644},
          zoom: 6
        });
        infoWindow = new google.maps.InfoWindow;

        // Try HTML5 geolocation.
        if (navigator.geolocation) {
          navigator.geolocation.getCurrentPosition(function(position) {
            var pos = {
              lat: position.coords.latitude,
              lng: position.coords.longitude
            };

            infoWindow.setPosition(pos);
            infoWindow.setContent('Location found.');
            infoWindow.open(map);
            map.setCenter(pos);
          }, function() {
            handleLocationError(true, infoWindow, map.getCenter());
          });
        } else {
          // Browser doesn't support Geolocation
          handleLocationError(false, infoWindow, map.getCenter());
        }
      }

      function handleLocationError(browserHasGeolocation, infoWindow, pos) {
        infoWindow.setPosition(pos);
        infoWindow.setContent(browserHasGeolocation ?
                              'Error: The Geolocation service failed.' :
                              'Error: Your browser doesn\'t support geolocation.');
        infoWindow.open(map);
      }
    </script>
    <script async defer
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
    </script>
  </body>
