Copying a CSV file and changing a column of data

[laredotornado]

Hi,

I'm using php 4.4.4. I have a CSV file that contains columns "A" and
"B". What is the simplest way to create a second CSV file with the
values of column "A" copied into column "B"? The other columns in the
file can be left alone.

Thanks, - Dave

Read in the file contents line by line, explode() the lines using the
comma as the separator string, swap the resulting arrays' first two
cell's contents, join()/implode() the array items in a string with the
comma separator, write them to a new file, unlink the first, rename the
new one, done.

Something like that?
Best!
