have tried sending data in post fields did not work. response:

<!doctype defaultrs system 'https://xml.rentalcars.com:443//tj.dtd'><defaultrs> <error id="2"> <message>premature end of file.</message> </error> </defaultrs> 

any appreciated. thanks

you need url encode xml data before can use query parameter. url assignment becomes:

$url = 'https://secure.rentalcars.com/service/servicerequest.do?   servername=www.rentalcars.com&xml='.urlencode(utf8_decode(trim($xml))); 

note, i've wrapped readability - should on 1 line.
