, at_nocenja
, be_turista
, be_nocenja
, ba_turista
... they is checking every day. i need to sum it all in php for report. is that posible?
Don't do it in PHP, that's needlessly selecting too much data from a database. All you gotta do is use a SUM()
and +
like so:
SELECT SUM(column1) + SUM(column2) + SUM(column3) + ... AS total
FROM table
WHERE <filters for a date or other requirements>
