In PHP using datetime.format what is the meaning of %a

Question

I’d like to know what the meaning of %a used in Data time in PHP, the others found here:

%Y Anos,
%m Meses,
%d Dias,
%H Horas,
%i Minutos,
%s Segundos

Would be the a in the table of PHP manual?

Answer 1

The complete table is on that other page of the documentation.

%a represents the period of the day with "am" or "pm" and is useful when displaying hours in the 12-hour format with %h.
