How can the ORDER BY clause be used to retrieve the latest entry from a table in PHP?

To retrieve the latest entry from a table in PHP, you can use the ORDER BY clause in conjunction with the DESC keyword to sort the results in descending order based on a timestamp or an auto-incrementing ID column. By ordering the results in descending order and limiting the query to return only the first row, you can effectively retrieve the latest entry from the table. 

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

// Prepare and execute the query to retrieve the latest entry
$query = $pdo->prepare("SELECT * FROM your_table ORDER BY id DESC LIMIT 1");
$query->execute();

// Fetch the latest entry
$latestEntry = $query->fetch(PDO::FETCH_ASSOC);

// Output the latest entry
print_r($latestEntry);
