Hi.

You can use the fopen() function with "a" as a second parameter to append to the end of a file.

To delete from the file it would probably be best to read it into a variable and use some of the string functions to edit it.
Unless it is a huge file, in which case you would probably need to read it in portions and overwrite it as you go.

Heya, Sokoun.

If you are reading and writing large amounts of data to this file, you might want to consider using a database as a more robust solution.
