尝试从数据库lat longs在Google Map上创建多个标记

Question

I have a database that gets latitude and longitude values inserted into it. I have created a PHP loop to pull these values out in an array and my hope is to create a marker for each point on a Google map. Here is the code that I need to adjust to do so:

<script type="text/javascript">
var mylat,mylong,request;
var directionsService = new google.maps.DirectionsService();
var directionsDisplay = new google.maps.DirectionsRenderer();

var map = new google.maps.Map(document.getElementById('map'), {
   zoom:7,
   mapTypeId: google.maps.MapTypeId.ROADMAP
 });


mylat= <?php echo $postalLat; ?>;
mylong = <?php echo $postalLong; ?>;
request = {
origin: mylat+','+mylong,
destination: '<?php echo $latRefDef; ?><?php echo $this->item->gpslat; ?>,<?php echo     $longRefDef; ?><?php echo $this->item->gpslong; ?>',
travelMode: google.maps.DirectionsTravelMode.DRIVING
 };


 directionsDisplay.setMap(map);
 directionsDisplay.setPanel(document.getElementById('panel'));
 directionsService.route(request, function(response, status) {
   if (status == google.maps.DirectionsStatus.OK) {
 directionsDisplay.setDirections(response);
 document.getElementById('loader').innerHTML = "";

   }
 });


//omitted database connection here to get array of values

$totalMarkers = count($results);

foreach($results as $result){
$gpsLats[] = $result->gpslat; 
$gpsLongs[] = $result->gpslong; 
}


$i = 0;
while ($i < $totalMarkers) {
$inc = $i++;

?>

var myLatlng = new google.maps.LatLng(<?php echo $gpsLats[$inc]; ?>,<?php echo $gpsLongs[$inc]; ?>);

var marker = new google.maps.Marker({
  position: myLatlng,
  map: map,
  title: 'Hello World!'
  });

<?php

}

?>

</script>

My thought was that since the javascript which creates each marker is within the while loop then I would get one marker per entry. Unfortunately this is not functioning as I would like it to, any ideas on how to adjust it?

Not 100% sure why it wasn't working out with all that php code, but I whittled it down to this and it works now:

<?php
while ($i < $totalMarkers) {
$inc = $i++; 
$myLats = $gpsLats[$inc];
$myLogns = $gpsLongs[$inc];
?>
var myLatlng = new google.maps.LatLng(<?php echo $myLats; ?>,<?php echo $myLogns; ?>);

var marker = new google.maps.Marker({
  position: myLatlng,
  map: map,
  title: 'Hello World!'
  });
<?php

}

?>
