Print XML response from PHP

I am working on a project which involves receiving an XML http post, processing it and storing it to an SQL database and returning a XML Response.

I have battled through and have the receiving script working fine but am having problems returning XML data. Below is was im currently using:


$xml_output = "<?xml version=\"1.0\" encoding=\"iso-8859-1\"?>\n";
$xml_output .= "<DELIVERY_2_SMS>\n";
$xml_output .= "\t<SMSMESSAGE>\n";
$xml_output .= "\t\t<DESTINATION_ADDR>01234567890</DESTINATION_ADDR>\n";
$xml_output .= "\t\t<TEXT>Thankyou for your Message</TEXT>\n";
$xml_output .= "\t\t<TRANSACTIONID>1</TRANSACTIONID>\n";
$xml_output .= "\t\t<TYPEID>2</TYPEID>\n";
$xml_output .= "\t\t<SERVICEID>1</SERVICEID>\n";
$xml_output .= "\t\t<COSTID>2</COSTID>\n";
$xml_output .= "\t</SMSMESSAGE>\n";
$xml_output .= "</DELIVERY_2_SMS>\n";

echo $xml_output;

Im assuming my 1st problem is line 1:
$xml_output = "<?xml version=\"1.0\" encoding=\"iso-8859-1\"?>\n";

when it gets to the end ?> it is closing PHP for the page. I have tried doing \"? >\n";
but when run, the page says invalid whitespace.
Is there a simply way round this or am i in the completly wrong direction?

Any assistance would be most appreciated
