Don't see why not, cookies are based on a domain, not a technology.

Try creating a simple cookie using CFCOOKIE then try reading it in with PHP in the way you normally would, I don't see why it wouldn't work. Bear in mind if you're using doing the write and read on the same page that I'm not sure at what point CF would write the cookie, whether it's as the page *begins* to render or finishes rendering.

Therefore the cookie may not be immediately apparent, but should be easy enough to test.

The contents of an iframe are a separate request to the request for the "main" window.  Frames and that sort of thing are a browser conceit: neither the web server nor CF have any idea how the requests will be handled on the browser, they just see two requests.  Both of which are handled like any other requests would be.  They have no relation to one another.

Why don't you just TRY IT and see if it works?  It'll only take 5min to knock together a test...

Like I said: as far as the servers are concerned (web server, CF & PHP servers), they are not "the same page".  Servers don't think in "pages" they think in "requests".  When a browser requests a web page which in turn has an iframe in it, that's two separate requests: one for the main page, one for the iframe.  They only look like "the same page" because that's how the browser chooses to render them.  On the server end of things they are two distinct & unrelated requests.

You might need to look at casing issues in regards to the cookie key names.  CF always capitalises them, I think, whereas PHP is case-sensitive.

You should probably use an HTTP sniffer to watch what cookie data is being moved too/from the browser/servers for each request.  That will probably shed some light on the scene...

Cookies may in fact depend on the technology. For example, I don't expect PHP to be able to make anything of Coldfusion's CFID and CFToken cookies.

Well yes quite, what the man with the signature said. I never said that PHP would be able to understand a CFID, simply that it could read it, which it can. If you want any kind of communication between PHP and CF I'd assumed you'd not be trying to use the built-in methods for authentication.

Right, it's as simple as expected. Two pages:

/index.php:

<?php
echo($_COOKIE['TESTVAR']) ;
?>

/index.cfm:

<cfcookie domain="mydomain.co.uk" name="testvar" value="Yee-hah!" />
<iframe src="/test.php">
</iframe>

Result when index.cfm is called? PHP outputs the value of the cookie as expected. Where's the issue? Or have I missed something?

I'm not sure, why don't you try it and see?
