Hi Internals,
I created my first php-src PR
<https://github.com/php/php-src/pull/13845> yesterday and anticipate I
may have to write an RFC for it. I created a wiki account under the
handle, "bilge", and the howto <https://wiki.php.net/rfc/howto> told me
to request RFC karma here.
About the PR: I sometimes find it would be useful to only update part of
the date. The PR makes all parameters to DateTime(Immutable)::setDate
<https://www.php.net/manual/en/datetimeimmutable.setdate.php> optional
in a backwards-compatible manner such that we can elect to update only
the day, month, year or any combination of the three (thanks, in part,
to named parameters). Without this modification, we must always specify
all of the day, month and year parameters to change the date.
To change just one part of the date, StackOverflow users have found
various novel
<https://stackoverflow.com/questions/60415815/setting-just-the-year-with-php-datetime>
ways
<https://stackoverflow.com/questions/18176794/adjust-a-php-date-to-the-current-year>
to work around setDate()'s current limitation, which generally involves
calling format() twice, to isolate the specific date parts that should
remain constant, and feeding them back into setDate() so they are
effectively unchanged. All this leads me to wonder why we can't just
call setDate() with only the parameters we want to change. This is
particularly useful when generating a collection of dates that only
differ in one aspect (year, day) and/or when working in a templating
environment, such as Twig, where doing all the format calls results in
multiple statements and logic overhead that we should like to avoid in
templating contexts.
Looking forward to hearing your thoughts.
Cheers,
Bilge
