What are some strategies for improving the readability and maintainability of PHP code when dealing with database queries?

When dealing with database queries in PHP, it is important to use prepared statements to prevent SQL injection attacks and improve security. Additionally, using meaningful variable names and comments can enhance readability. To improve maintainability, consider separating database logic into separate functions or classes for better organization. 

// Example of using prepared statements for improved security and readability
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username);
$stmt->execute();
$results = $stmt->fetchAll();
