[PHP] << Previous n Articles

[jtjohnston]

I'm using this code to create a "Next n Articles >>" on my index.page
from my mysql database.
I worked most of it out myself. Then I got some help. It works. I
thought I understood my own code enough to be able to construct a "<<
Previous n Articles". I guess not. My coding skills need help.
So how do I reverse my code to construct the previous n articles from my
sql database.

if(!$offset)
{
$offset = 0;
}
$limit = 5;
$num_rows = 13;#I get this from a mysql operation

#####################################################
$new_offset = $offset + $limit;
$disp = $limit;
if ($new_offset + $limit > $num_rows)
{
  $disp = $num_rows - $new_offset;
}
if ($disp > 0)
{
  $nextinsert  = " <font face=\"arial\" size=2><A
HREF=\"index.html?offset=".$new_offset."\">Next ".$disp." Articles
&gt;&gt;</a></font>\n";
}

<g> Thanks if you have a second.

John
