Connecting to SOAP services in PHP 4

Hi, I’m a newbie in SOAP, and I ask to someone that can help me to connect and interact to a SOAP server, but using PHP 4.3.X. I have to use a service that’s only available by SOAP, but I only can use PHP 4.3, cause it’s the version in my ISP server. How can I do this? Is there any way to go around using curl or something like it? Is there any tool in linux that could help me? Thanks in advance. Hugo Alexandre Dias Eng.
