Help with PHP installation

[Brian-W.O.G]

Hey all, I'm posting this message to ask how to correctly install PHP. I've tried twice with no luck. The reason I'm getting into PHP is because I've been doing HTML for awhile (and I'm starting Javascript) and I want to send E-mails to myself for forms, polls, and surveys.

Also, I've tried to upload the PHP code to my FTP server and try to run it with my webpage. That didn't work either. I just gave me the classic "Page cannot be displayed" page (after I submit the form information).

Thanks for your time,

God bless,

Brian
