My question why $i output not increase (always 0) so that the “hello” word never printed. Thx for help

Answer 1

You are selecting only one column, so count($datarow) is every time exactly 1. The while loop loops over every row selected from database and the for cycle is trying to loop over selected columns, which is always 1 on every row, so $i is never increased and every time reinitialized to 0.
