Both %U and %W seem to return what you want, using strftime. I'd guess that
date would also have flags for these.
No. That's one thing I've wondered sometimes.
According to documentation:
strftime has:
Week --- ---
%U Week number of the given year, starting with the first Sunday as the
first week 13 (for the 13th full week of the year)
%V ISO-8601:1988 week number of the given year, starting with the first
week of the year with at least 4 weekdays, with Monday being the start
of the week 01 through 53 (where 53 accounts for an overlapping week)
%W A numeric representation of the week of the year, starting with the
first Monday as the first week 46 (for the 46th week of the year
beginning with a Monday)
date has:
Week --- ---
W ISO-8601 week number of year, weeks starting on Monday (added in PHP
4.1.0) Example: 42 (the 42nd week in the year)
Also then ISO-8601 week number is kind of mixed, or is older iso
week something different than in 1988 version of the standard=
By description they both %W and W do the same, but other one
is ISO-8601 and in strftime ISO-8601:1988 is %V which is different.
Or is it so that strftime %V is same as date's W, both are really the
iso week's but description for date forgets to mention about that
"at least 4 weekdays".
So at least someone could fix the documentation to be exact to
one don't have to guess or rtfs.
