What are some potential pitfalls of using free web hosting services for PHP websites?

One potential pitfall of using free web hosting services for PHP websites is limited resources and slow loading times due to overcrowded servers. To improve performance, you can optimize your PHP code by minimizing database queries and reducing file sizes. Additionally, consider upgrading to a paid hosting plan for better reliability and support. 

// Example of optimizing PHP code by reducing database queries
// Instead of querying the database multiple times, store the results in variables

$query = "SELECT * FROM users WHERE id = 1";
$result = mysqli_query($connection, $query);
$user = mysqli_fetch_assoc($result);

// Use $user variable instead of querying the database again
echo $user['username'];
