I'm not 100% sure I understand your question; are you separating your
'pages' by entering the text "<!--pagebreak-->" in your content, and
then using the explode() method to break up the pages?
If that is correct, then given:
$allPages = explode('<!--pagebreak-->', $content);
$pageCount = count($allPages); // total # of pages found
$currentContent = $allPages[$_GET['page']]; // current page content
Hope that helps,
Carl.
