Hi guys. I have following code to delete particular row from a table based on the title. But how can I delete all data from the table?

PHP Code:
<?php
require 'connpdo.php';
$naslov $_POST['naslov'];
#DELETE DATA
//delete some data
$sqlInsert 'DELETE FROM bloging WHERE title=:title';
$preparedStatement $conn->prepare($sqlInsert);
$preparedStatement->execute(array(':title' => $naslov));
