What follows is a feature request.  Searching the existing feature requests have not turned up any similar results.

I have found that it might be convenient to allow include() and/or require() to be able to accept a variable as input.

A couple of scenarios that this might be useful:

* Caching script segments
* Evaluating PHP inside of templates

My workaround has been to dump a variable to disk and then include it as a file, after determining a unique file name to use.  After including the file, it was deleted from disk.  This was for a templating system that could recursively include other templates that may or may not include php.

The reason for the approach was to reuse php as a the template scripting language, as well.  Performance on my test server has been okay, but I am sure that with a large amount of traffic, the file i/o would slow the process down considerably.
