}

// Search

if(isset($_POST['search']))
{

    $search_Query = "SELECT * FROM users WHERE id = $data[0]";
    
    $search_Result = mysqli_query($connect, $search_Query);
    
    if($search_Result)
    {
        if(mysqli_num_rows($search_Result))
        {
            while($row = mysqli_fetch_array($search_Result))
            {
                $id = $row['id'];
                $fname = $row['fname'];
                $lname = $row['lname'];
