What are common pitfalls when using switch statements in PHP for handling MySQL query results?

Common pitfalls when using switch statements in PHP for handling MySQL query results include forgetting to handle default cases, not properly sanitizing input, and not accounting for all possible query result values. To avoid these pitfalls, make sure to include a default case in the switch statement, sanitize input using prepared statements or parameterized queries, and handle all possible query result values.

// Example of handling MySQL query results using switch statement with proper error handling

// Assume $result is the result of a MySQL query

switch ($result) {
    case "value1":
        // Handle value1
        break;
    case "value2":
        // Handle value2
        break;
    default:
        // Handle default case or throw an error
        break;
}
