How can PHP developers ensure that sensitive data, such as passwords, are securely stored in a database?

To ensure that sensitive data such as passwords are securely stored in a database, PHP developers should never store passwords in plain text. Instead, passwords should be hashed using a strong hashing algorithm like bcrypt before being stored in the database. This adds an extra layer of security by making it difficult for hackers to retrieve the original password even if they gain access to the database. 

// Hashing the password before storing it in the database
$password = 'mySecurePassword';
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Storing the hashed password in the database
// $db->query("INSERT INTO users (username, password) VALUES ('myUsername', '$hashed_password')");
