php - mysql special date output format -


as part of live chat script uses php/mysql on serverside , js/jquery on clientside want output date of each message in special format.

if message send today this(for example): today 22:30, if sent yesterday : yesterday 12:30 , if send before yesterday should output date format: dd.mm.yy h:i (for example 28.05.14 22:19).

of course know php easily, better performance want using sql.

i´ve read lot in mysql documentation altough found lot of date formating, couldn´t find this.

now want know if possible sql?

the date of each message stored timestamp in db.

use query below. must fulfill requirements(with or without modifications).

select if(date_format(`created`, '%y-%m-%d') = date(now()),     'today ' + date_format(`created`, '%k:%i'),     (select if(date_format(`created`, '%y-%m-%d') < date(now()),         (select if(date_format(`created`, '%y-%m-%d') = (date(now() - interval 1 day)),             'yesterday ' + date_format(`created`, '%k:%i'),             date_format(`created`, '%d-%m-%y %k:%i'))),             'no display'         )     ) ) user;

note: here 'created' date intending fetch user table.

for date_format ( ) function description , parameters used check link http://www.w3schools.com/sql/func_date_format.asp

hope helps . . .
