It's not pointers but string parsing (getting out a section of a string
and formatting a string to contain exact lengths of string).

I don't wish to sound offensive, but if you can't correctly write to an
XML file without errors, why do you think you'll be able to do it to a
flat file using functions/methods you don't know?
Also, bear in mind if you use a database it will also handle locking from
multiple processes easily, which you will have to handle yourself in this
situation.
Don't think "we'll only have one user accessing their account through a
single web instance so we won't have concurrency issues" - people these
days may use browser tabs to work on their mail concurrently.
And you really do run the risk of data loss/corruption if you don't
correctly lock access to the file.
Cheers,
Andy
