PHP PDO CRUD отображение данных на основе выбора значения коробки

я делал практику PHP PDO CRUD примера codingcage ... ссылка http://www.codingcage.com/2015/04/php-pdo-crud-tutorial-using-oop-with.html - в index.php я создал поле выбора с динамическим значением:PHP PDO CRUD отображение данных на основе выбора значения коробки

$conn = new mysqli('localhost', 'root', '', 'kk') or die ('Cannot connect to db'); 

$result = $conn->query("SELECT DISTINCT project FROM tbl_activitymaster where ProjectFlag='open' "); 

echo "<html>"; 
echo "<body>"; 
echo "<select name='unqprj'>"; 

while ($row = $result->fetch_assoc()) { 

       unset($project, $project); 
       $project = $row['project']; 
       $name = $row['project']; 
       echo '<option value="'.$project.'">'.$project.'</option>'; 
       $value="<?php echo $project;?>"; 
      } 

echo "</select>"; 
echo "</body>"; 
echo "</html>";

Но проблема заключается в том, как использовать это поле выбора в примере crud для фильтрации записей на основе выбранного значения. Я сделал это в asp.net, но в php, как это сделать. любая помощь, пожалуйста, или любую ссылку

Создайте форму, используйте массив '$ _POST'. –
