That's not really possible.

You can insert html into php, but not the other way round.

However, you could use an IFRAME. These are often used for advertising.

Here is an example....

<IFRAME WIDTH=468 HEIGHT=60 MARGINWIDTH=0 MARGINHEIGHT=0 HSPACE=0 VSPACE=0 FRAMEBORDER=0 SCROLLING=no BORDERCOLOR="#000000"
 SRC="http://www.something.com/whatever.htm">

</iframe>

It only works in Internet Explorer, I think.

Of course, you could just use normal frames.

I am not sure what to recommend to you because I haven't seen your website. Please give me the url of the html page you want your php page to appear in and I might be able to help you more.

Replace it with what?

I suggest you read a book on html and php programming, or find an online tutorial.

I went to http://nba2001live.lunarpages.com/html/contact.cfm , it looks exactly like http://www.nba2001live.lunarpages.com/mail.php

What is there to replace?

I have no idea how to help you, not because I'm not familiar with the internet, just because your question is so open-ended and vague I have no idea how to answer it.

Sorry.

Please could you try phrasing your question differently.

Ah, I'm pleased to hear that it works now!

I came back to the board just now and wasn't sure if you'd still be stuck or not.

Well done anyway (especially if English is not your native language, it must be twice as hard)
