I need help with some code I'm new to PHP so don't get too harsh.

Heres all the code I've separated it into separate files though

index.php
<?
$title="PHP Index";
$menu=include_once("php/menu.php");
$body=include_once("php/body.php");
include_once "php/templates/complexTemplate.php";
?>

php/menu.php
<?
print("Menu");
?>

php/body.php
<?
print("body")
?>

<?
print <<<END
<HTML>
<HEAD>
<TITLE>$title</TITLE>
</HEAD>
<BODY>
<TABLE width=100%>
<TR>
<TD width=30%>
$menu
</TD>
<TD>
$body
</TD>
</TR>
</TABLE>
</BODY>
</HTML>
END;
?>

and this is the output.
Menubody
1 1

why isn't the "Menu" and the "body" separated and what is up with the two 1's

thanks for any help
