How can LIMIT and ORDER BY be used to limit the output to the last 4 entries in a PHP script?

To limit the output to the last 4 entries in a PHP script, you can use the LIMIT and ORDER BY clauses in your SQL query. By ordering the entries in descending order based on a timestamp or an auto-incrementing ID, you can then use LIMIT 4 to retrieve only the last 4 entries. This will ensure that the output is limited to the most recent entries in the database. 

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Select the last 4 entries from the database
$query = "SELECT * FROM mytable ORDER BY id DESC LIMIT 4";
$stmt = $pdo->query($query);

// Display the results
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}
