Populating a Drop Down list with data from a database

Small script that demonstrates how to populate a drop down list or menu with data retrieved from a database using PHP and MYSQL. Below I copy / pasted a sample data that I’m use as well as the MYSQL statement to query the database.

Drop down list 

<form method="" name="testForm" id="testForm">

      <label>drop down select </label> 

      <select name="user_list" >

           <?php 

                foreach($get_userList as $user) { 

                    echo '<option value=' . $user['index'] . '>' . $user['FirstName']." " .

                          $user['FirstName'] .'</option>';

                } 

            ?> 

         </select> 

    </form>

Database query

Try {

     $stmt = $pdo->query('SELECT * FROM tb_testing'); 
     $get_userList = $stmt->fetchAll(PDO::FETCH_ASSOC);  
    }
    catch(PDOException $e) { 
        echo $e->getMessage().'Unable to access table'; 
    }

Sample data:

Array

(
    [0] => Array
        (
            [user] => 1
            [FirstName] => Trevor

            [Phone] => 1-392-702-0719
        )

    [1] => Array
        (
            [user] => 2
            [FirstName] => Grady
