Here is my code. There's is a "Edit" link. I want to update data and save with that link
    $op_sql = "SELECT * FROM tbl_users"; 
    $result = $con->query($op_sql); 
    if ($result->rowCount() > 0) 
    { 
    echo "<table class='table' style='margin-left: 301px; margin-top: 10px; background-color: white;'>-; 
    echo "<tr>"; 
    echo "<th>ID</th>"; 
    echo "<th>Name</th>"; 
    echo "<th>Email</th>"; 
    echo "<th>Date of Birth<th>"; 
    echo "<th></th>"; echo "</tr>"; 
    while($row = $result->fetch())
    { 
    echo "<tr>"; 
    echo "<td>" . $rowrID1 . "</td>"; 
    echo "<td>" . $row['Name'] . "</td>"; 
    echo "<td>" . $row['Email']. "</td>"; 
    echo "<td>" . $row['Date of Birth'] . "</td>";
    echo "<td><a href='?id=".$row['ID']."'>Edit</a></td>"; 
    echo "</tr>"; 
    } 
    echo "</table>"; unset($result);
