What are the potential security risks associated with using a database in PHP development?

One potential security risk associated with using a database in PHP development is SQL injection attacks, where malicious users can manipulate SQL queries to access or modify data. To prevent this, developers should use prepared statements or parameterized queries to sanitize user input before executing SQL queries. 

// Using prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username);
$stmt->execute();
