How do I make Soap calls using PHP SoapClient to salesforce without the Salesforce PHP Toolkit? -

$client = new soapclient('enterprise.wsdl'); print_r($client->login(sfdc_login, sfdc_password.sfdc_api_token)); $client->__setlocation(token_url); 

i receive error:

fatal error: uncaught soapfault exception: [unknown_exception] unknown_exception: destination url not reset. url returned login must set in sforceservice in /library/webserver/documents/custom/index.php:18

in case doesn't provide useful information, tell me either need set destination url or catch returned url? appreciated.

note:

i don't want use salesforce php toolkit because don't want add company web server, if don't have to.

ok, after digging aynber's idea. came this...

i downloaded soapui-5.2.1 mac https://www.soapui.org.

from there combined program enterprise wsdl file salesforce. using program "pre build" soap call me. pulled out pieces needed , used curl submit soap envelope.

this allowed me convert leads using created account ids/contact ids. after converting lead, able go , modify opportunity id created pre lead conversion.

here code came with...

$soapsubmission='<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:enterprise.soap.sforce.com"><soapenv:header><urn:sessionheader><urn:sessionid>'.$creds[0].'</urn:sessionid></urn:sessionheader></soapenv:header><soapenv:body><urn:convertlead>';         foreach($postinfo $orderkey=>$values){             $additionstring='<urn:leadconverts>';             if(isset($values['sfdc_ids']['account'])){                 $additionstring.='<urn:accountid>'.$values['sfdc_ids']['account'].'</urn:accountid>';             }             if(isset($values['sfdc_ids']['contact'])){                 $additionstring.='<urn:contactid>'.$values['sfdc_ids']['contact'].'</urn:contactid>';             }             $additionstring.='<urn:convertedstatus>converted</urn:convertedstatus>';             $additionstring.='<urn:donotcreateopportunity>true</urn:donotcreateopportunity>';             $additionstring.='<urn:leadid>'.$values['sfdc_ids']['lead'].'</urn:leadid>';             $additionstring.='<urn:overwriteleadsource>false</urn:overwriteleadsource>';             $additionstring.='<urn:ownerid>'.self::it_service_id.'</urn:ownerid>';             $additionstring.='<urn:sendnotificationemail>false</urn:sendnotificationemail>';             $additionstring.='</urn:leadconverts>';              $soapsubmission.=$additionstring;         }         $soapsubmission.='</urn:convertlead></soapenv:body></soapenv:envelope>';          $ch=curl_init($creds[1]);         curl_setopt($ch,curlopt_returntransfer,1);         curl_setopt($ch, curlopt_maxredirs, 10);         curl_setopt($ch,curlopt_timeout, 60);         curl_setopt($ch,curlopt_post,1);         curl_setopt($ch,curlopt_postfields,$soapsubmission);           curl_setopt($ch, curlopt_httpheader, array(             "cache-control: no-cache",             "content-type: text/xml; charset=utf-8",             "soapaction: convertlead"           ));         $result=curl_exec ($ch);         curl_close($ch);         return $result;
