how to htmlencode this string to help prevent javascript injections?

Hello all,

I am wanting to htmlencode the following piece of code so as to help prevent against javascript injections. Any clues? It's a piece of code used in displaying page number navigation. The $blogMetaData part is throwing me off and my head's getting sore from banging the wall.

<div class="blogpagenumber">
  <?php if ($blogMetaData['invalidPageNum']): ?>
    Results page '<?php echo $blogMetaData['page'] ?>' not found, <a href="<?php echo $blogMetaData['firstPageLink'] ?>">start over &gt;&gt;</a>.<br><br>
  <?php elseif (!$blogRecords): ?>
    <br>
    Those records are not currently available.  Please click BACK in your browser.<br><br>
  <?php endif ?>
  <?php if ($blogMetaData['prevPage']): ?>
    <a href="<?php echo $blogMetaData['prevPageLink'] ?>">&lt;&lt;&nbsp;previous&nbsp;</a>
    <?php else: ?>
  <?php endif ?> 
  <?php
	  if (@!$_GET['page']): $current_page = "1";
	  else: $current_page = $_GET['page'];
	  endif;
  ?>
  <?php foreach (range(1, $blogMetaData['totalPages']) as $page): ?>
    <?php if ($page == $current_page): ?>
      <span class="blogbordertext">&nbsp;page&nbsp;<?php echo $page; ?>&nbsp;</span>
      <?php else: ?>
        <a href="?<?php echo http_build_query(array_merge($_REQUEST, array('page' => $page))) ?>"><?php echo $page; ?></a>
    <?php endif ?> 
  <?php endforeach; ?>
  <?php if ($blogMetaData['nextPage']): ?>
    <a href="<?php echo $blogMetaData['nextPageLink'] ?>">&nbsp;next&nbsp;&gt;&gt;</a>
    <?php else: ?>
  <?php endif ?> 
</div>

Thank you kindly for any and all assistance.
