[Maccabee]

Ok because I cant veiw peoples php there are things I cant find out.

So here is my question?

Is it better to do this:

< ?php include ("header.php"); ? >

< ?php include ("nav.php"); ? >

< ?php include ("ad.php"); ? >

Content

< ?php include ("foot.php"); ? >


or condense header,nav and ad .php into one file and do this:

< ?php include ("tophalf.php"); ? >

content

< ?php include ("foot.php"); ? >

Get what im saying?

If you dont can someone just send me a code of what their site looks like with the php.
