If you have to do it all in PHP, I would pass a start-file index to the
page; something like this:
<?php
$ind = ( isset($ind) ? $ind : 0 );
$dir_name = "e:\celebs\christina_aguilera";
$dir = opendir($dir_name);
$prev = ( $ind > 0 ); // should 'prev' be active?
$next = false; // should 'next' be
active?
$ignore = array(".", ".."); // files to skip
$i = 0;
while ($fname = readdir($dir)) {
if (in_array($fname, $ignore))
continue;
if ($i >= $ind) {
if ($i < $ind + 15) {
echo "\n<br> $fname";
}
else {
$next = true; // more files; make 'next'
active
break;
}
}
$i++;
}
closedir($dir);
$prev_pre = ( $prev ? '<a href="#?ind='.max($ind-15,0).'">' : '' );
$prev_post = ( $prev ? '</a>' : '' );
$next_pre = ( $next ? '<a href="#?ind='.$ind+15.'">' : '' );
$next_post = ( $next ? '</a>' : '' );
echo "\n<br>$prev_pre <<prev $prev_post | $next_pre next>>
$next_post";
?>
This will skip '.' and '..' without counting them, will enable/disable the
'prev' and 'next' links as needed, will ignore all files past $ind+16 (it
has to read one past the end to know if 'next' should be enabled), and will
automatically stop when it runs out of files. It will work for all
browsers, at a cost of increased server load.
Personally, I would consider writing all the filenames into a JavaScript
array, and do the paging on the client.
