how to replace text

[extacy]

So i know this is probably in php.
i need a code that places what ever the person puts in with E.G email

<%
Set myMail=CreateObject("CDO.Message")
myMail.Subject="Sending email with CDO"
myMail.From="[email protected]"
myMail.To="EMAIL"
myMail.TextBody="This is a message."
myMail.Send
set myMail=nothing
%>

were it says EMAIL is were i want what ever that person puts in to be places, and to check if its a real email, how would i do that?

That doesn't look like PHP to me, looks like ASP.
