PHP: HTTP or HTTPS? How can one tell?

[elijahparker]

How can I tell if a php page was accessed via http or https?

I already tried this seemingly simple solution, but for me it does not work. How can this be? Any ideas?

[PHP]<?php echo $_SERVER['SERVER_PROTOCOL']; ?>[/PHP]


simply returns:

HTTP/1.1

Whether the page is accessed via http or https.

I never realized this little thing could be such a challange! Any ideas would be greatly appreciated. Thanks!

Name-based virtual hosting cannot be used with SSL secure servers because of the nature of the SSL protocol. if you config your apache base on Name-based(More than one web site per IP address), this solution doesn't work.
