The short answer is use a database.  The long answer is to write your
function to reverse the array.  You could have the original array passed
to the function and your function return a reversed one.  In your
function, you would have to do some checking.  If the index is a new
entry into your guestbook, then create a new index in the new array.  If
not, just prepend the text to the last index of the array.

I'm imaging that your text file is delimited by something.  You may want
to explode each line so you can tell if it belongs together or not.

[PHP] Problems after reversing a guestbook

[Mogens Nielsen]

Hey there!

This is my absolutely first time posting in a newsgroup, so be nice please
; )
I've written a guestbook, and in an attempt to get the newest entries first
I reversed the guestbook-txt-file. Like so:
$tabell = file( gjestebok.txt );
$revtab = array_reverse( $tabell );

$antall = count( $revtab );

$i = 0;

if( !( $fil = fopen( guestbook.txt, r+ ) ) )
die();

while( $i  $antall )
{
  fwrite( $fil, $revtab[$i] );
  $i++;
}

fclose( $fil );

Now the problem: If I post a message with a line of text, a newline (as in
hitting the return-key), some more text and newlines, these
newline-separated text-lines show before the posting itself after reversing
because they are independent elements in the array.
