How can PHP error messages be effectively utilized to troubleshoot issues related to saving checkbox values in a database?

Issue: When saving checkbox values in a database using PHP, errors can occur due to incorrect handling of the checkbox values or database operations. To troubleshoot these issues, utilize PHP error messages to identify the root cause, such as incorrect data types or SQL syntax errors. 

// Example PHP code snippet for saving checkbox values in a database

// Assuming checkbox values are submitted as an array
$checkbox_values = $_POST['checkbox_values'];

// Convert array to a comma-separated string for database storage
$checkbox_string = implode(",", $checkbox_values);

// Perform database query to save checkbox values
$query = "INSERT INTO table_name (checkbox_column) VALUES ('$checkbox_string')";

// Execute query and handle errors
if(mysqli_query($connection, $query)) {
    echo "Checkbox values saved successfully";
} else {
    echo "Error: " . mysqli_error($connection);
}
