What are some potential pitfalls when using prepared statements in PHP, especially when dealing with large amounts of data?

One potential pitfall when using prepared statements in PHP, especially with large amounts of data, is not properly binding parameters. This can lead to SQL injection vulnerabilities and potentially compromise the security of your application. To solve this issue, always make sure to bind parameters correctly when using prepared statements. 

// Example of binding parameters correctly in a prepared statement
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");
$stmt->bindParam(':username', $username, PDO::PARAM_STR);
$stmt->execute();
