What are the potential risks of directly using MySQL permissions for user access control in a PHP-based web application?

Directly using MySQL permissions for user access control in a PHP-based web application can pose security risks as it tightly couples the application with the database server, making it harder to manage permissions at the application level. To mitigate this risk, it is recommended to implement a separate user access control system within the PHP application itself. 

// Implementing user access control in PHP application

// Check user permissions before executing a query
if ($user->hasPermission('read_data')) {
    $query = "SELECT * FROM data_table";
    $result = $mysqli->query($query);
    
    // Process query result
} else {
    echo "You do not have permission to read data.";
}
