IMO It is bad to store lots of data in session variables.
The $_REQUEST var for the post/get should be enough.
URL: search.php?page=10
code:
$conf['maxresultsperpage'] = 10;
$ref = mysql_query("select count(*) as c from table where subject like '%foo%'");
list($cnt) = mysql_fetch_array($ref); // will assoc work here? dunno, didn't test
echo "Displaying ".($conf['maxresultsperpage']*$_REQUEST['page'])-9." through
".($conf['maxresultsperpage']*$_REQUEST['page']).".";
$ref = mysql_query("select subject, data from table where subject like '%foo%'
limit ".$conf['maxresultsperpage'].",
".($conf['maxresultsperpage']*$_REQUEST['page'])-10);
// loop through array returned from mysql
echo "<a href='url?page=".$_REQUEST['page']+1."'>Next</a>";
I think. It might need some tweaking, but you get the idea (I hope).
No need to store variables here.
