Protected Page: PHP

Is there anyway to make a page protected with a password through php alone?

I think yes.

Im not heavily into php yet. There are only a few things that I know well. But you should be able to 'require' or 'include' a file in your HTML document, before you enter the <.html> tag that will call another php script that will perform Basic HTTP authentication. If you use BASIC HTTP, you will still need a .htaccess and .htpassword file.

You might be able to do it through 'sessions' though. If you are able to, this is the way I would go. And you could also experiment with cookies that will allow previously authenticated users to not have to log in. I think MobileBadBoy has played with sessions, so you may try emailing him, or join the #teamps irc channel on irc.othersideirc.com and ask him.

Yes, it's possible using PHP. The best way is to use sessions like Axiom said. I would give you code, but I don't have the time to type it up and everything thing I've done in password protection is proprietory. I know http://www.hotscripts.com has some PHP modules that do this including phpSecurePages (my favorite).

Here a little help from me.

Header("WWW-authenticate: basic realm=\"PROTECTED\"");
Header("HTTP/1.0 401 Unauthorized");
