The following code assumes/requires:
$result : an array containing the results from a query
the number of items in the array is the number of
rows returned from the query.
$frm[batchpos] : a value that is passed from page to page containing
the position at which to begin displaying the current
page
$frm[batchsize] : a predefined variable to control how many records are
displayed per page
#------------------------------------------------
if ($result) {
## Extract only the relevant batch of results to display
## ($frm[batchpos] -> $frm[batchpos]+$frm[batchsize])
## Display the results navigation bar
$RESULT_COUNT = count($result);
$result = array_slice($result, $frm['batchpos'], $frm['batchsize']);
$BATCHES = ($RESULT_COUNT / $frm['batchsize']);
$RESULT_LINK = "Results: ";
for ($i = 0; $i < $BATCHES; $i++) {
$disp_start = ($i * $frm['batchsize']) + 1;
$disp_end = $disp_start + $frm['batchsize'] - 1;
if ($disp_end > $RESULT_COUNT) { $disp_end = $RESULT_COUNT; }
$link_batchpos = $i * $frm['batchsize'];
if ($disp_start != $disp_end) {
$link = "[$disp_start - $disp_end] "; }
else {
$link = "[$disp_start]";
}
if ($frm['batchpos'] != $link_batchpos) {
$link = "<a href='$PHP_SELF?".
rawurlencode("frm[category]")."=".rawurlencode($frm['category'])."&".
rawurlencode("frm[batchpos]")."=".rawurlencode($link_batchpos)."'>".
$link."</a>";
}
$RESULT_LINK .= $link;
}
}
echo $RESULT_LINK;

The above is for reference only. Obviously you would need to change things to
suit your situation and needs.
