What are the potential security risks of accessing an Access database over VPN using PHP?

Potential security risks of accessing an Access database over VPN using PHP include data interception, unauthorized access, and SQL injection attacks. To mitigate these risks, it is recommended to use secure VPN protocols, implement proper authentication and authorization mechanisms, and sanitize user inputs to prevent SQL injection vulnerabilities. 

// Example of sanitizing user inputs to prevent SQL injection
$unsafe_variable = $_POST['user_input'];
$safe_variable = mysqli_real_escape_string($connection, $unsafe_variable);
