Clearer Time Values with Carbon
Lots of applications involve date and time manipulation. Whether it's figuring out what day of the week it is, how many seconds are in a week or how many hours are in a century.
Quite often, you'll see something like:
$minutesInAWeek = 7 * 24 * 60
On a small scale, it's quite clear what is going on, but if you wrap this bit of logic in a function or another calculation, you can quickly lose sight of what
Lets take our example above and use these constants to make what's happening clearer:
use Carbon\Carbon; $minutesInAWeek = Carbon::DAYS_PER_WEEK * Carbon::HOURS_PER_DAY * Carbon::MINUTES_PER_HOUR;
Yes, it's verbose. But this kind of verbosity is good, in my opinion.
If we wanted to take this further and figure out how many seconds are in a year, we could do:
use Carbon\Carbon; $minutesInAWeek = Carbon::DAYS_PER_WEEK * Carbon::HOURS_PER_DAY * Carbon::MINUTES_PER_HOUR; $secondsInAYear = $minutesInAWeek * Carbon::SECONDS_PER_MINUTE * Carbon::WEEKS_PER_YEAR;
There's some more constants too, you can check out the full list in the documentation.
