What are the potential risks of solely relying on a security framework/package without understanding the underlying security principles in PHP coding?

Relying solely on a security framework or package without understanding the underlying security principles in PHP coding can lead to a false sense of security. It is essential to have a solid understanding of security principles to properly implement and customize security measures for your specific application needs.

// Example of implementing a basic security measure in PHP
$userInput = $_POST['user_input'];
$filteredInput = htmlspecialchars($userInput, ENT_QUOTES, 'UTF-8');
// Use $filteredInput in your application to prevent XSS attacks
