Here's something which might be useful, please don't just use the code as-is but take it's ideas and concepts (and main function hehe) to fit into your project. The code provided will (should) work in a standalone manner just to show you everything. It uses preg_split, I'm sure there are other alternatives of which this is just one example.
PHP Code:
<?php
/**
* Splits a document by <h5>...</h5> elements
*
* This function does all of the work for you, hopefully.
* Simply feed it an article and it will spit out
* the pages in an array containing title and body items.
*/
function split_pages($szArticle, $szTag = 'h5')
{
$aPages = array();
$szTag = preg_quote($szTag);
$szPattern = '#^\s*<' . $szTag . '>(.*?)</' . $szTag . '>\s*#im';
$aItems = preg_split($szPattern, $szArticle, -1, PREG_SPLIT_DELIM_CAPTURE);
array_shift($aItems);
// Loop through and sort into title/body groups
for ($i = 0, $l = count($aItems); $i < $l; $i = $i+2)
{
if (!isset($aItems[$i+1]))
continue;
$aPages[] = array('title' => trim($aItems[$i]),
'body' => trim($aItems[$i+1]));
}
return $aPages;
}
// Here is our article to use
$szArticle = '<h5>Title for Page 1</h5>
Page one content
<h5>Title for Page 2</h5>
Page two content
<h5>Title for Page 3</h5>
Page three content';
// Gather the necessary variables together
$aPages = split_pages($szArticle);
$iPage = (isset($_GET['page']) && array_key_exists(intval($_GET['page']) - 1, array_keys($aPages))) ? $_GET['page'] : 1;
$aPage = $aPages[$iPage - 1];
/*
Now onto some examples of how you might
like to use the pages array.
*/
?>
<!-- Show us what the $aPages array looks like -->
<pre><?php print_r($aPages) ?></pre>
<hr>
<!-- Show Current Page -->
<h2>Page <?php echo $iPage ?>: <?php echo $aPage['title'] ?></h2>
<p><?php echo nl2br($aPage['body']) ?></p>
<hr>
<!-- Pagination, Navigation, whatever you want to call it -->
<ol>
<?php foreach ($aPages as $t_iPage => $t_aPage) : $t_iPage++; ?>
<li>
<a href="?page=<?php echo $t_iPage ?>">
Page <?php echo $t_iPage ?>: <?php echo $t_aPage['title'] ?>
</a>
</li>
<?php endforeach; ?>
</ol>
