in reply to Make PHP Execute in CGI output

Ok, maybe it's not the easier way, but I think it will work:

1) First create a file and put the code into it.
2) Make the browser load the file.

For an example (using your code): 
open (THP, ">foo.php"); # THP means TemporaryPHP hehe
print THP>>The_End;
<!-- Initial HTML code-->
<?php include('header.php'); ?>
<body>
<!--rest of doc-->
</body>
</html>
The_End
close (THP);
print "Location: http://URL_to_the_file/foo.php\n\n";
