ok, if you're using mysql you can use the LIMIT function
in your statement:
SELECT * FROM table LIMIT 0, 30
would show 30 rows starting from row 1.
you can set a variable telling your php script how many
entries per page you will show:
$showlines = 10;
and telling your script where to start the search
$start = ($page * showlines) - $showlines;
and you're sql should look like:
SELECT * FROM table LIMIT $start, $showlines
so if you're on page 3, it'll look like this:
$start = (3 * 10) - 10 // 20 is our startpoint
SELECT * FROM table LIMIT 20, 10
this would show 10 lines starting from line 21
