Previous Question Next Question

To prevent SQL injection attacks, use parameterized queries or prepared statements, which ensure that user input is treated as data rather than executable code.

<!-- BEGIN COPY / PASTE -->
    // Example using a parameterized query in PHP with PDO
    $stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
    $stmt->execute(['username' => $inputUsername]);
    $user = $stmt->fetch();
    <!-- END COPY / PASTE -->

Additional Comment:

Always validate and sanitize user inputs, even when using parameterized queries.
Use ORM frameworks that inherently protect against SQL injection.
Regularly update your database libraries to patch known vulnerabilities.
