I would like to know how you do faster calculation in php if you have to
do such as simple calculation ,column 4=coumnl1*column2*column3 and then do summation of column4 for 5000 rows.
In excel VBA, I will use rg.offset(0,0).FormulaR1C1="rc2*rc3*rc4", where rg as range from A1 to A5000
something like, it will copy the formula into every cell of 5000 rows in Excel,
and speed is really fast to get the final answer.
How about we do it in php, we just save all column and rows cells into array
then loop all row cells and do basis calculation. Any other method available will
be fastest in php ?
