For anyone else that may stumble upon this thread looking for the same thing; simply add this PHP code wherever you want that EZpage content to show up:

Code:
<?php $var_pageDetails = $db->Execute("select * from " . TABLE_EZPAGES . " where pages_id = 2");
echo $var_pageDetails->fields['pages_html_text']; ?>
Replace the number 2 with whatever EZpage ID you want (eg. where pages_id = 4")
