php xml mozilla confusion

[Prodoc]

I created two different files with almost the exact same content.
file.xml contains pure xml data
file.php contains the exact same data except the first line, this on is
changed to

<?
echo ("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
?>

instead of just

<?xml version="1.0" encoding="utf-8"?>

If I request the xml file in Mozilla or IE it displays the xml content
like those browsers normally do (a nice colorfull tree structure) but if
I request the php file only IE displays it the exact same way as the xml
file (nice and colrfull again), Moz outputs one straight line of text.

Is this a php problem where IE interprets it wrong again and desides to
display it the xml way or is this a browser problem where Moz interprets
it wrong (because it might only display it as nice and colorfull if it
has the xml extension)?

A .xml file has a text/xml mime type. A .php file doesn't. Make this the
first line of your .php file:

<? header ("Content-Type: text/xml"); ?>

I gave it a try but php doesn't seem to be bothered with using

echo ("<?xml version=\"1.0\" encoding=\"utf-8\"?>");

while I've got the short tags enabled.
Joshua's suggestion did the trick solving the problem by adding

<? header ("Content-Type: text/xml"); ?>

I can't change the server setting because loads of pages have to be
altered if I do.
