Answer 1

There would be a lot of different ways to achieve this. I prefer to use array_map to get the values out of the object and convert the values. The it should be easy enough for array_sum to sum it all together.

$hours_array = array_map("get_hours", $array);
$results = array_sum($hours_array);

function get_hours($object) {
    // Check values first

    // For just hours.
    list($hours,) = explode(":", $object->{'total_time'});

    return $hours;
}

Follow this steps:

• loop over array;
• convert HH:MM format to seconds like this;
• sum all converted seconds;
• convert summed seconds back to HH:MM format like this.
