Paul, here is how I would approach your problem (if I have understood 
it correctly. I'm sure the experts on the list will be
able to improve this code, but it does work:

INDEX.PHP
session_start();

// get stuff from the db, unshown
$pagePointer = 0;
while( $row = mysql_fetch_row( $result ) {
   // store each row in the session
   $_SESSION['pages'][$pagePointer] = $row;
   $pagePointer ++;
}
// count how many rows we have
$_SESSION['pageCount'] = count( $_SESSION['pages'];
// redirect to the display
header( Location:pages.php?start=0 );

PAGES.PHP
<?php
session_start();

// orient ourselves
$start = $_GET['start']; // error checking skipped
$last = $_SESSION['pageCount'] - 1; // arrays start at 0, count starts at 1
$previous = $start - 1;
if ( $previous < 0 ) $previous = $last;
$next = $start + 1;
if ( $next > $last ) $next = 0;

// display this one somehow
print_r( $_SESSION['pages'][$start] );
// provide links to move through each page
?>
<br />
<a href="pages.php?start=<?= $previous ?>">previous</a><br />
<a href="pages.php?start=<?= $next ?>">next</a>
