Transfer Data from Database to Leaflet POP UP

Good Day too all! I just wanna ask a little question. Ahmm how do you show data from database to leaflet pop up?

Here is my code in php select command

<?php 
$db = new PDO('mysql:host=localhost;dbname=poi', 'root', ''); 
$sql = "SELECT name,user_date,user_time,address,lat,lng,icon_name FROM tblmarker"; 

$rs = $db->query($sql); 
if (!$rs) { 
    echo "An SQL error occured.\n"; 
    exit; 
} 

$rows = array(); 
while($r = $rs->fetch(PDO::FETCH_ASSOC)) { 
    $rows[] = $r; 
    $name[] = $r['name'];
    $user_date[] = $r['user_date'];
    $user_time[] = $r['user_time'];
    $address[] = $r['address'];
    $icon_name[] = $r['icon_name'];
} 
print json_encode($rows); 
$db = NULL; 
?> 

and here is my code in showing the marker in the map from database

function getInfo() { 
        $.getJSON("get_info.php", function (data) { 
          for (var i = 0; i < data.length; i++) { 
            var location = new L.LatLng(data[i].lat, data[i].lng); 
            var marker = new L.Marker(location,{icon:Icon1}); 
            var ll = marker.getLatLng();

          marker.bindPopup("$name<br>$user_date<br>$user_time<br>$address<br>$icon_name").addTo(map); 

             } 
        }); 
      } 

I thought it works because when i refresh it the marker from my database shows in the map but when i click the marker for the pop up the pop up shows only is like this.

$name
$user_date
...

Whats wrong with my code? Am I missing something? TYFH and IA
