Writing to a file. (PHP)

[Nasimov]

It's possible to ammend data within a file vs. just adding data to the beginning or the end of the file? Mean to change something in the "middle" of the file.
Thanks.

hmmm... I'm not so sure... I would say you could load all the text of the file into a textarea box and then let the user edit it and simply replace it all... that's my idea.

What kind of file is it just a txt file.
