Help with fwrite mode...!

[Anon]

Hello, again I need your professional help; I made a script that automatically adds a link to my site, and I used to store informations and links in a .txt file.

Then I include it in a .php page and it displays the table with the name, link, ecc...

But the problem comes when I add more then 1 link: the newest one is under the older one...how can I have the newest posted as first?

I'm using this instruction:

$fp = fopen ($filename , "a");

Thanks,
Alberto

I had that very same problem and the only way I found to do it was this:

$fp_old = file( "linkfile.txt" );
$fp_new = fopen( "linkfile.txt", 'w' );
flock( $fp_new, 2 );

$linkline = "the links details";

fwrite( $fp_new, $linkline );
foreach( $fp_old as $fpold_new )
{
fwrite( $fp_new, $fpold_new);
}
flock( $fp_new, 3 );
fclose( $fp_new );

It means that the file gets wiped and re-written each time but it works fine. You can see how it works at http://www.demoncheese.co.uk/submitlink.php

What if the file is several hundreds of thousands of lines? How do we get it to the top without reading in and writing back 7+ meg of text?
