Show scripts on wordpress

I have several fully functional php scripts that I would like to use and display on our WordPress site.

I need a solution that allows us to display these scripts functionally on the front end of our site. I do not want to use iframes or anything like this. The content from the scripts needs to be able to be seen by search engines and indexed.

If you already have a simple way to do this that is great, otherwise we need someone to create a plugin or some other solution that will allow us to display these scripts functionally on our sites front end. What ever solution you may provide will need to be explained so that we can apply it to all of the scripts that we are trying to use.

If you are a WordPress developer this should be a super simple project, that wont take very long. You may already have the solution stored somewhere.

If you have any further questions please let me know.
