Adding PHP tags before and after html code

Hi, Im a very new user to X11Pro and have enjoyed sinking my teeth into something new. However I use often for clients sites a CMS system that requires me to place this code at line 1
<?php
ob_start();
?>

and this code at the very end

<?php include '/home/***clientname****/public_html/a-agents/app/views/pjLayouts/pjActionLoad.php'; ?>

I found the place holder option to have my content load, and by adding the snippets above the page works fine. I just don't want to have to add this via an editor each time there is a page or site change. :confused:
