<br /> in xml string

[Anon]

hi all!

i create an xml string like that:

$string = "<?xml version=\"1.0\" ?>";
$string .= "<root>";
$string .= "<something>" . $this->foobar . "</something>";
$string .= "</root>";

and then look at the result:

echo $string;

but whats that? there is a <br /> at the end of my xml string.

<?xml version="1.0" ?><root><something>foobar</something></root><br />

does anyone know where this <br /> comes from and how to remove it?

thanks, marc
