like i wanted to make a spreadsheet out of using several form input fields then each fields represent an element in the array

variable[x][y]

where X is column and Y is row

i won't have memory hog problem having 64 x 120 array?

Yes, you can.

Code:

<input type="checkbox" name="ids[][]" value="<?php echo $i->id; ?>" />

Look the name="ids[][]"

If you do a

Code:

var_dump($this->input->post('ids'));

you'll see your array.

The memory can be a problem. Depends how you write your code, in special the loop section.
