What are common challenges faced when using "Open Survey Pilot" for PHP development?

One common challenge faced when using "Open Survey Pilot" for PHP development is handling and validating user input effectively to prevent security vulnerabilities such as SQL injection or cross-site scripting attacks. To address this issue, it is important to sanitize and validate all user input before using it in any database queries or outputting it to the browser. 

// Sanitize and validate user input
$user_input = $_POST['user_input'];
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Use prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $sanitized_input);
$stmt->execute();

// Output sanitized input to the browser
echo htmlentities($sanitized_input);
