How can PHP developers effectively troubleshoot and test their code when working with the "SET" data type in MySQL tables?

When working with the "SET" data type in MySQL tables, PHP developers can effectively troubleshoot and test their code by ensuring that they are correctly handling the data retrieved from the database. They should verify that the data is being processed and displayed accurately according to the values set in the "SET" column. Additionally, developers can use conditional statements or switch cases to handle different combinations of values in the "SET" column. 

// Example code snippet for handling "SET" data type in MySQL tables
$query = "SELECT set_column FROM table_name";
$result = mysqli_query($connection, $query);

while ($row = mysqli_fetch_assoc($result)) {
    $set_values = explode(",", $row['set_column']);
    
    foreach ($set_values as $value) {
        // Handle each value accordingly
        switch ($value) {
            case 'value1':
                // Code for value1
                break;
            case 'value2':
                // Code for value2
                break;
            // Add more cases as needed
        }
    }
}
