Trouble with duplicate content and supplemental pages

[castar]

I'm not sure if I'm in the correct place, but have a problem. Not even sure if it's a scripting issue.

We pages showing up in the serps like this www.mysite.com/page.php/anotherpage.php. These pages are all on my site only I have them set up as www.mysite.php/page.php. We are receiving duplicate content because both of these are showing up in G and now most of my pages are now supplemental. I need to fix this asap. Any suggestion? Thanks in advance to those who respond and Merry Christmas.

Not sure I understand your question

So you mean to say that your website has 2 identical content pages

namely

www.mysite.com/page.php/anotherpage.php

and

www.mysite.com/anotherpage.php.

and like wise

www.mysite.com/page.php/anotherpage1.php

www.mysite.com/anotherpage1.php and so on?
