Are there any specific PHP functions or methods that can simplify the process of summing time values in a database?

When summing time values in a database, it is important to convert the time values to seconds, perform the sum operation, and then convert the result back to a time format for display. One way to simplify this process is to use the `TIME_TO_SEC()` function in MySQL to convert time values to seconds before summing them in a query. This allows for the summing of time values directly in the database query rather than in PHP code. 

// Example query to sum time values in a database using TIME_TO_SEC() function
$query = "SELECT SEC_TO_TIME(SUM(TIME_TO_SEC(time_column))) AS total_time FROM table_name";
$result = mysqli_query($connection, $query);

if ($result) {
    $row = mysqli_fetch_assoc($result);
    $total_time = $row['total_time'];
    echo "Total time: " . $total_time;
} else {
    echo "Error: " . mysqli_error($connection);
}
