<div class="textblock"><p>Handles returning arrays based on a given pagenumber. </p>
|
|
<p>By specifing a $_GET['pagenum'] or if not(page = 1 will be used) a few elements from a specific query will be returned. Not all elements have to be loaded into objects, only the elements needed for that specific page, this is a good thing performance wise. This is done by passign the query to the constructor and specifying how many you want to display. </p>
