Previous Question Next Question

To prevent SQL injection attacks, it's crucial to use parameterized queries and prepared statements, which ensure that user input is treated as data rather than executable code.

<!-- BEGIN COPY / PASTE -->
    // Example of a parameterized query in PHP using PDO
    $stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
    $stmt->execute(['username' => $userInput]);
    <!-- 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 by design.
Regularly update your database and application software to patch known vulnerabilities.
