[SOLVED]Why is embedded php not in _main

Hi All,
I try to embed existing PHP code into an article with element type=html, htmlcode= {{file::phpfile.php}}
when I open this page, the contao template is gone and only the php output is rendered on the screen.
I expected that teh php output was show in the main area.

I will probably need an iframe to solve this behavior ? how should I do that ?

any help is appreciated
thx
