What are some security considerations when storing login credentials in a database using PHP?

When storing login credentials in a database using PHP, it is crucial to securely hash the passwords before storing them to prevent unauthorized access in case of a data breach. Additionally, using prepared statements with parameterized queries can help prevent SQL injection attacks. It is also important to properly secure the database connection and restrict access to sensitive information. 

// Hash the password before storing it in the database
$password = password_hash($_POST['password'], PASSWORD_DEFAULT);

// Use prepared statements to prevent SQL injection
$stmt = $pdo->prepare("INSERT INTO users (username, password) VALUES (:username, :password)");
$stmt->bindParam(':username', $_POST['username']);
$stmt->bindParam(':password', $password);
$stmt->execute();
