Comparing two rows in a loop

PHP
1

Hello

How can I compare rows in a loop?

for e.g

if column data for row 1 is: 525
and column data for row 2 : 800
I want to divide row 1 by row 2.

Initialize a variable with a row.
Start loop (WHILE there is a new row)
Compare new row to old row.
Set old row variable to hold new row.
End loop.

Hi,

How would I “Initialize a variable with a row.”?

Thanks
