white space and create hidden form fields as you go. Also note that each hidden form field is an array
whose key corresponds to the line number you ’ re processing in the $csv array. This may sound
confusing, but it will keep all your data neatly packaged when it comes time to process it. You want to
end up with an array of elements, with line numbers for keys and the corresponding data for each line as
the values. That way you can easily unpack what you need on the other side and have it match the
incoming CSV data.
