PEAR / Soap Problem

Hi all, I have got a question regarding your Pear / SOAP Package. After installing Pear and the Soap package I am not able to execute the following PHP script: //simple example to check soap extension client is working.. dl('soap.so'); echo "create client\n"; $soapclient = new SoapObject("http://services.xmethods.net/soap/urn:xmethods-delayed-quotes.ws dl"); echo "sending getquote\n"; $ret = $soapclient->getQuote("ibm"); print_r($ret); echo "done"; The problem is that 'soap.so' is not found at all on the system. The following message comes up: Warning: Unable to load dynamic library '/usr/lib/php4/soap.so' - /usr/lib/php4/soap.so: cannot open shared object file: No such file or directory in /var/www/html/test.php on line 11 Where is soap.so distributed? Have you got any suggestions? I am using Rad Hat 7.3, and the Soap 0.7.1 package. Any Help Would be appreciated! Thanks, Jan Bruns
