is it possible to use php when you use the built-in page editor?

I think so, but I don't know exactly what you're talking about because I don't know WordPress. Apparently if you use any bad PHP, your entire WordPress dies.

all i need to do is include something, so it shudn't die

I found PHP Validator by accident once. It adds a button into the editor, and you can use the button to trial the code for errors before you save. I've never used it.

thats not what i meant, i want to be able to use php in posts or pages because if i add it it wont parse but show the php
