What are potential pitfalls when trying to fill a switch case function dynamically from a database in PHP?

When trying to fill a switch case function dynamically from a database in PHP, a potential pitfall is the lack of error handling for cases where the database query fails or returns unexpected results. To solve this issue, you should always check the database query result before using it to populate the switch case statement. Additionally, make sure to handle any potential errors gracefully to prevent unexpected behavior in your application. 

// Assume $db is a PDO database connection
$query = $db->query("SELECT * FROM cases_table");
$cases = $query->fetchAll(PDO::FETCH_ASSOC);

if ($cases) {
    foreach ($cases as $case) {
        switch ($case['case_value']) {
            case 'value1':
                // Handle case value 1
                break;
            case 'value2':
                // Handle case value 2
                break;
            // Add more cases as needed
            default:
                // Handle default case
                break;
        }
    }
} else {
    // Handle database query failure or no results
}
