Question

我从数据库中获得了纬度，经度和地址。如何在谷歌地图上显示每个商店的价值：

 $qry = mysqli_query($link,"select * from store");
 while($row = mysqli_fetch_array($qry)){
 $lat = $row['lat'];
 $long = $row['lng'];
 $adresse = $row['Adresse'];
 }

如何在谷歌地图上一个接一个地显示每个商店的地址。在我的代码中，它只显示一个map.how来显示每个地图？

        //JS function

    window.onload=initMap;

     function initMap() {

            var map = new google.maps.Map(document.getElementById('map'), {
              zoom: 4,             
            });
           show_markers();
          }
/*
Considering you have php array with locations
in format ('address'=>add1,'lat'=>lat1,'lng'=>lng1)
$qry = mysqli_query($link,"select * from store");
$marker_data = mysqli_fetch_array($qry);
*/



     function show_markers(){
         var locations = <?php echo json_encode($marker_data);?>;

            for (i = 0; i < locations.length; i++) {  
          marker = new google.maps.Marker({
            position: new google.maps.LatLng(locations[i]['lat'], locations[i]['lng']),
            map: map
          });

          google.maps.event.addListener(marker, 'click', (function(marker, i) {
            return function() {
              infowindow.setContent(locations[i]['address']);
              infowindow.open(map, marker);
            }
          })(marker, i));
        }
    }
