What potential pitfalls should be considered when using PDO bindValue in PHP?

When using PDO bindValue in PHP, it's important to be aware of potential pitfalls such as SQL injection attacks if user input is not properly sanitized. To prevent this, always validate and sanitize user input before binding it to a parameter in a prepared statement. 

// Example of using PDO bindValue with proper input sanitization
$userInput = $_POST['input'];
$cleanInput = filter_var($userInput, FILTER_SANITIZE_STRING);

$stmt = $pdo->prepare("SELECT * FROM table WHERE column = :input");
$stmt->bindValue(':input', $cleanInput);
$stmt->execute();
