In what ways can the PHP code for updating database records be improved for better readability and maintainability?

To improve the readability and maintainability of PHP code for updating database records, it is recommended to use prepared statements to prevent SQL injection attacks, separate the database logic from the presentation layer using functions or classes, and use meaningful variable names and comments to explain the code's purpose. 

// Improving readability and maintainability of PHP code for updating database records

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

// Prepare the SQL statement with placeholders
$stmt = $pdo->prepare("UPDATE users SET name = :name, email = :email WHERE id = :id");

// Bind the parameters to the placeholders
$stmt->bindParam(':name', $name);
$stmt->bindParam(':email', $email);
$stmt->bindParam(':id', $id);

// Execute the statement
$stmt->execute();
