?>
<html>
<title></title>
<body>
<h2>Here are the records for page <?php echo $current_page; ?></h2>
  <ul>
    <?php echo $slots; ?>
  </ul>
Page <?php echo $current_page; ?> of <?php echo $total_pages; ?>
<br />
<?php echo "{$first} | {$prev} | {$next} | {$last}"; ?>
</body>
</html>

So basically this code above makes it easy to put up images and their links. For now, I don’t have that many images, so the page runs super fast. However, I’m thinking in the long run. If I have say, 10,000 images, it’s gonna take a long time to process each paginated page, as I would have $image_links of file1/page1 up to file10000/page10000, and 10000 different image descriptions! Is there a way to stop the web browser from reading, or skip, certain parts of the script (the $image_links and $image_descriptions in my case)? That way, it won’t need to read through all 10000 $image_links and $image_descriptions.

Thanks!

    What people usually do in this kind of a situation is to store a record of each image in a database. That way you don’t have to create the whole list of images each time. So you would only retrieve the images for the page that a user is currently viewing.

    Caching

    You can also cache your results. There are all sorts of methods, classes and libraries to do that, but it basically involves doing something like this:

    $cache_key = 'cache-page-'.$pagenumer.'.cache';
if (!file_exists($cache_key)) {

    ob_start();
    // all your code comes here - to make it very
    // fast, you can do an include() here on the other file
    include 'the-rest-of-your-code-example.php';
    $output = ob_get_clean();
    $fp = fopen($cache_key, 'w');
    fwrite($fp, $output);
    fclose($fp);

} else {
    $output = file_get_contents($cache_key);
}

// And finally echo the content
echo $output;
