394561 Txt file parser script

Hello, I am looking for a small php script that when I load a | a pipe deliminated file into the script it would place a date to the data on every line starting with the current server date. So it would add mm/dd/yy| to each line with the date being addeded with the pipe end | to in groups of two. so it would would change dates for every two items like 02/27/10|content 02/27/10|content 02/28/10|content 02/28/10|content and so on.. It would continue like a calendar for the remainder of the file line by line of course of the data present is more than one line it would still look for the break of the | to determine the next line to continue the theory. Please advise.
