Are there any security concerns to consider when using text files as a database in PHP?

When using text files as a database in PHP, one security concern to consider is the risk of SQL injection attacks if user input is not properly sanitized. To mitigate this risk, always use prepared statements or parameterized queries when interacting with the text file to prevent malicious SQL commands from being executed. 

// Example of using prepared statements to insert data into a text file database
$pdo = new PDO('sqlite:/path/to/database.db');

$stmt = $pdo->prepare("INSERT INTO users (username, password) VALUES (:username, :password)");
$stmt->bindParam(':username', $username);
$stmt->bindParam(':password', $password);

$username = $_POST['username'];
$password = password_hash($_POST['password'], PASSWORD_DEFAULT);

$stmt->execute();
