As you are wanting to use a PHP client, I would use PHP cURL functions for SOAP. Someone posted a similar problem and a cURL solution was provided, see Execute SOAP using cURL... although this was for POST you would do something similar for GET. Either way you will receive a server response through the "curl_exec($ch)" function. I suggest looking at the cURL function reference on PHP help for more detail.
This basically retrieves information from the server. There are various methods to then display this information on a webpage (e.g. one method would be through an "echo" command).
