Here is my code,Inside the infowindow content i have used some html code,that i have to replace with php variables.
for Eg:deviceid1 should be replaced with value from database

  var trieste = new google.maps.LatLng(45.6111555,13.8022614);
  var mapOptions = {
    zoom:      12,
    center:    trieste,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }

  var map = new google.maps.Map($("#map_canvas")[0], mapOptions);

  var places =
    [
      {
        "position": [45.6466883,13.7631226]
      },
      {
        "position": [45.6433281,13.7895584]
      },
      {
        "position": [45.6017884,13.6673355] 
      },
      {
        "position": [45.622442,13.7641525] 
      }
    ]

  var currentPlace = null;
  var icons=["green.png","red.png","blue.png","yellow.png"];
  var i=0;

    $(places).each(function() {
      var place = this;
      var marker = new google.maps.Marker({
        position: new google.maps.LatLng(place.position[0], place.position[1],place.position[2],place.position[3]),
        map     : map,
        icon    : icons[i]
      });

   if(i==0)
   {
   var infowindow = new google.maps.InfoWindow({
   content: '<ul><li>Device ID1</li><li>Device configuration1</li><li>Device Description1</li></ul><a href="riacqua/activepanel.php">Goto RIACQUA</a>'
     }); 
   google.maps.event.addListener(marker, 'mouseover', function() {
   infowindow.open(map, marker);
     });
    google.maps.event.addListener(marker, 'mouseout', function() {
   infowindow.close();
     });
    }

Are you just trying to do something like thsi?

var infowindow = new google.maps.InfoWindow({
   content: '<ul><li><?php echo $deviceId; ?></li><li>Device configuration1</li><li>Device Description1</li></ul><a href="riacqua/activepanel.php">Goto RIACQUA</a>'
     }); 

That should do the trick, of course if your device id variable contains quotes/single quotes then you may have to strip them or escape them.

This should work no problem with a php file, but you may need to change other settings if you are trying to get this to render in another file type (html, htm, etc).
