PHP Script convertsion from Mysqlnd to mysqli

Question

Anyone help me to find the alternative code for my script because it requires Mysqlnd and many online servers don't have this so if I use this code It will give me this error

Fatal error: Call to undefined method mysqli_stmt::get_result()

So I want someone to change my code into mysqli version.

My Code:

  $page_id = mysqli_real_escape_string($con, $page_id);

$select_query = $con->prepare("select ID, Title, image, Cost, Vid, content from mobs where ID=?"); 

$select_query->bind_param('i', $page_id);

$select_query->execute();

$result = $select_query->get_result();

while ($row = mysqli_fetch_array($result, MYSQL_ASSOC))

{
    $post_id = $row['ID']; 
    $post_title = $row['Title'];

Update 1

if(isset($_GET['ID'])){

$page_id = $_GET['ID'];

      $page_id = mysqli_real_escape_string($con, $page_id);

$select_query = $con->prepare("select ID, Title, image, Cost, Vid, content from mobs where ID=?"); 
$select_query->execute();
$select_query->bind_result($post_id, $post_title, $post_image, $post_cost, $post_vid, $post_cont);

while ($select_query->fetch()) {      


    $post_id = $row['ID']; 
    $post_title = $row['Title'];
    $post_image = $row['image'];
    $post_cost = $row['Cost'];
        $post_vid = $row['Vid'];
            $post_cont= $row['content'];

    $sign = '$';
        $sign = mysql_real_escape_string($sign);


?>

Update 3

if(isset($_GET['ID'])){

$page_id = $_GET['ID'];



$select_query = ("select ID, Title, image, Cost, Vid, content from mobs where ID=?"); 

$select_query->execute();
$select_query->bind_result($post_id, $post_title, $post_image, $post_cost, $post_vid, $post_content);

while ($select_query->fetch())
 echo 'Post ID:', $post_id, '<br>',
         'Post title: ', $post_title;
 {

mysqli_stmt::get_result is only available in PHP >= 5.3.0.

I suggest using bind_result instead.

Also, you don't need to escape any strings used in bind_param.

$select_query->execute();
$select_query->bind_result($post_id, $post_title, $post_image, $post_cost, $post_vid, $post_content);

while ($select_query->fetch()) {
    // do stuff with the bound result variables, eg
    echo 'Post ID:', $post_id, '<br>'
         'Post title: ', $post_title;
}
