How should the database connection be handled in PDO to avoid issues like the one described in the forum thread?

Issue: The issue described in the forum thread is likely due to not properly handling database connections in PDO. To avoid issues like this, it is important to ensure that database connections are properly closed after use to prevent resource leaks and potential connection errors. Fix: To avoid issues like the one described in the forum thread, it is recommended to use try-catch blocks to handle exceptions and ensure that the database connection is properly closed using the `close()` method. Here is an example of how to handle the database connection in PDO: 

<?php
try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    // Perform database operations here

} catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
} finally {
    $pdo = null; // Close the database connection
}
?>
