Inseritng a php form

[Sirrel Squirrel]

I've completely forgotten how to do this but I want to insert a php email form on an html page, the form in question is an email form where people enter their name, email address and message but I can't for the life of me remember how to insert it on the html page.

edit/ I know I spelt inserting wrong lol

No worries, I've worked it out, was just being really bloody stupid lol

Still being a bit stupid, all I did was paste in the php parts from my email form into the html page, which made all the entry fields appear but above that is all the validation code, which now displays for everyone to see, how do I implement that?
