Good day to everyone!
Anybody could give step by step PHP code or explanation with examples of how to get the information to other page.
For example my main page is index.php inside of it I have three links to the following PHP files: roland.php, haydee.php and ricky.php.
Now, if I'm going to click each links. I want to be displayed the information of those three files (roland.php, haydee.php and ricky.php.) inside index.php. The address bar will be looked something like this: index.php?page=haydee.

I'm hoping your favorable assistance.

Thank you very much...

Roland
