What are some potential pitfalls of using free webspace with PHP and MySQL?

One potential pitfall of using free webspace with PHP and MySQL is the lack of security measures in place, leaving your website vulnerable to attacks such as SQL injection. To prevent this, always sanitize user input before executing SQL queries to prevent malicious code from being injected into your database. 

// Sanitize user input before executing SQL queries
$user_input = $_POST['user_input'];
$sanitized_input = mysqli_real_escape_string($connection, $user_input);

// Use the sanitized input in your SQL query
$query = "SELECT * FROM users WHERE username = '$sanitized_input'";
$result = mysqli_query($connection, $query);
