use MySQL result for include()

[Anon]

I'm working on a site that's structured a lot like Everything2: content in a database that's navigated through a php file that serves as a template for each page. Fairly easy stuff. The pages in the database have their own html; the php is mainly a shell for selecting and navigating nodes.

What I want to do is store pages that can include their own php code, and have that code evaluated. It should act just like I'm using include() on a file - an html page with php embedded. Currently, I'm using a straight MySQL query to retrieve the data and echo it.

In perl, I'd use something like an eval statement. How do I get the same effect with php?

On rereading, I thought I should be a bit more specific.

What I want is to use include() on a string (from the database), rather than a file. The string will normally contain text and html, but I want to be able to evaluate any php code that might be in there.

I looked at eval(), but that function treats a string as php code, which will not be the case with the string returned from the database.

If $mystring contains HTML with embedded PHP code,

eval(" ?> $mystring <? ");

Bang. That's exactly it. Thanks.
