curl method for web serivce name

Hi,

how to invoking PHP curl method on a server and the response will be XML type. Curl will save the output. I need to fetch data from a web service name i-e 'GetPVForServiceProviders'

The web service contain secure urls and these urls are in 'xsd' format i-e 'http://www.abc.com/PaymentVoucher.xsd'

Code is like:

<PaymentVoucher xmlns="http://www.abc.com/PaymentVoucher.xsd">
<ErrorInfo>
<ErrorCode>Integer</ErrorCode>
<ErrorEnglish>String</ErrorEnglish>
<ErrorArabic>String</ErrorArabic>
</ErrorInfo>
</PaymentVoucher>

Can I use this kind of web service with PHP? if yes then what will be best way to use this web service because I need to receive and send data using php and save to mysql.
