appending file with new line first

Hello, Yep, me again, with yet another php question. Maybe I'm too tired to see the easy solution... I open a file and write to it: $handle = fopen ($temp_file, 'a'); fwrite($handle, $original_info); fclose ($handle); Later I want to add to the above file: $handle = fopen ($temp_file, 'a'); fwrite($handle, $new_info); fclose ($handle); Here's what the file now looks like: original info original info original info original info new infonew info I'm trying to achieve: original info original info original info original info new info new info It writes the very first piece of new info on a new line. That is good. The second piece of new info gets written right at the exact end of the file. I've tried fwrite($handle, $new_info\n) but that creates an error. So does fwrite($handle, $new_info\r); How can I get the new info to go on its own line in the file? Thanks, Roger
