YES! I was working that out as well. One correction though, this line should read: $temp_int_id = trim(substr($file_array[$i], 21, 4));
I guess the lesson learned is to use substr() when the length of the $string is fixed. Since I have to use substr() and trim() twice, I wonder if this has more or less overhead than a single regular expression? Thank you.
