read from txt-file to php

pls check the 2 attached files, [login to view URL] first. i dont want to insert every new email-adress in that [login to view URL], so i'd like to open the txt-file from the php-site, to get the data. for example: .../[login to view URL] should open txt-file, get the data which belongs to "101" and bring it back to php. txt-file has to be tab-separated because i want to work with it in xls. thanks!
