Hi Listmembers,
Does anyone know of a way to "append" to the head of a flat file instead of
end?
I am creating a listing in which the output of a flat database file is read
into an HTML page using SSI. The file is created by a form and each entry
is now appended to the end of the database. I would like the new entry to
be written to the head of the file instead. "Reverse Cronology" so to
speak.
I am on a UNIX server, running Apache and Perl 5.004.
As an alternative I was thinking of trying to write a Perl routine to
reverse the order of the file and call that in the SSI instead of just
importing the file, but I would rather get the import file in the order that
I want first so that I don't have to call another script to get the same
results.
Example:
Now the database looks like this:
URL 1<br>Description1<br>
URL 2<br>Description2<br>
URL 3<br>Description3<br>
I want it to look like this:
URL 3<br>Description3<br>
URL 2<br>Description2<br>
URL 1<br>Description1<br>
Thanks in advance for any help.
Jan
