   3       12.33          17.33           Dieseased
   4       13.44          17.55           Healthy
   5       11.32          17.66           Imbalanced
   6       12.33          18.33           Healthy
   7       14.44          18.44           Healthy
   8       11.22          17.22           Balanced

I have slightly made changes in my code pl follow: I am able to get "Healthy" but If I select "Balanced" it should show only Balanced treeid & lat , long

  <?php

  define('&#95;&#95;ROOT&#95;&#95;', dirname(dirname(&#95;&#95;FILE&#95;&#95;))); 
require&#95;once(&#95;&#95;ROOT&#95;&#95;.'/public&#95;html/Config.php');


 // Connecting to mysql database
    $mysqli = new mysqli(DB&#95;HOST, DB&#95;USER, DB&#95;PASSWORD, DB&#95;DATABASE);

   // json response array
   $response = array();


$sq = "SELECT treeid, treelatitude, treelongitude FROM tree WHERE (treecondition = 'Healthy','Balanced')";

  if (isset($&#95;POST['treecondition'])) {

// receiving the post params

 $treecondition = $&#95;POST['treecondition'];

// get the tree details for google map marker
if($stmt = $mysqli->query($sq)){

   if ($stmt->num&#95;rows) {


       while($tree = $stmt->fetch&#95;assoc()) {

        $treeItem = array();

        $treeItem["treeid"] = $tree['treeid'];
        $treeItem["treelatitude"] = $tree['treelatitude'];
        $treeItem["treelongitude"] = $tree['treelongitude'];
        $response[] = $treeItem;

 }  echo json&#95;encode($response);

  }

  }else {
     // user is not found with the credentials
 $response["error"] = TRUE;
 $response["error&#95;msg"] = "Tree list view credentials are wrong. Please try again!";
 echo json&#95;encode($response);
  }
  $mysqli->close();
 }
