javascript - Google Maps Multiple Markers. What is wrong with my code? -


so have code below. doesn't show when run it. white blank page on browser. should googlemap markers(multiple) on it. want know wrong code because doesn't show error @ all.

<!doctype html>  <html>   <head>     <meta http-equiv="content-type" content="text/html; charset=utf-8" />     <title>google maps multiple markers</title>     <script src="http://maps.google.com/maps/api/js?sensor=false"             type="text/javascript"></script>  </head>   <body>    <div id="map" style="width: 500px; height: 400px;"></div>      <?php include 'location.php';?>        <script type="text/javascript">      var locations = <?php echo json_encode($location); ?>;        var map = new google.maps.map(document.getelementbyid('map'), {        zoom: 10,        center: new google.maps.latlng(6.40, 125.60),        maptypeid: google.maps.maptypeid.roadmap      });        var infowindow = new google.maps.infowindow();        var marker, i;        (i = 0; < locations.length; i++) {    		loc_array = locations[i].split(",");    		marker = new google.maps.marker({  			position: new google.maps.latlng(loc_array[1], loc_array[2]),  			map: map  		});    		google.maps.event.addlistener(marker, 'click', (function(marker, i) {  			return function() {  				infowindow.setcontent(loc_array[0]);  				infowindow.open(map, marker);  			}  		})(marker, i));      }    </script>  </body>  </html>

and location.php file contains following data:

<?php  $servername = "localhost";  $username = "root";  $password = "";  $dbname = "tsunami_simulation";    // create connection  $conn = mysqli_connect($servername, $username, $password, $dbname);  // check connection  if (!$conn) {      die("connection failed: " . mysqli_connect_error());  }    //========================================================  	$sql='select a.household_name, b.latitude, b.longitude household a, location b a.household_id = b.household_id;';  	$result = mysqli_query($conn, $sql);  		  	if(mysqli_num_rows($result) > 0){  		// output data of each row  		  		//while($row = mysqli_fetch_assoc($result)) {          //echo "household name: " . $row["household_name"]. " - latitude: " . $row["latitude"]. " - longitude " . $row["longitude"] ."<br>";  		//}		  		for($i=0;$i<mysqli_num_rows ( $result );$i++){  			$row=mysqli_fetch_row($result);    			$location[]= $row[0].', '.$row[2].', '.$row[1].','.($i+1);  		}  		  	}else{echo "0 results";}  ?>

first of have syntax error right here 

var locations = <?php echo json_encode($location); ?>;

change 

var locations = "<?php echo json_encode($location); ?>";

after should have string in locations variable have create object 

locations = json.parse(locations)
