What are the potential benefits of optimizing a database in PHP?

Optimizing a database in PHP can lead to improved performance, faster query execution, reduced server load, and overall better scalability of the application. This can be achieved by using indexes on frequently queried columns, normalizing the database structure, avoiding unnecessary joins, and optimizing queries to fetch only the required data. 

// Example of optimizing a database query in PHP using indexes
$query = "SELECT * FROM users WHERE email = :email";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':email', $email, PDO::PARAM_STR);
$stmt->execute();
