Doesn't the SOAP_SINGLE_ELEMENT_ARRAYS option work for a SOAP server in php?

I'm trying to get an array, although there is one element in the list. The problem is described here https://stackoverflow.com/questions/19050621/single-array-element-becomes-object-with-zend-soap-client But I have a server. Trying to accept this code:

request body

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:bu="http://debug.xxxxx.loc/xxxx"> <SOAP-ENV:Header/> <SOAP-ENV:Body> <bu:contractTypeDictionary SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <dictionary> <item> <V_Code>STRING</V_Code> <V_Name>STRING</V_Name> <GUID>STRING</GUID> <IsGroup>BOOLEAN</IsGroup> <GUID_Parent>STRING</GUID_Parent> </item> </dictionary> </bu:contractTypeDictionary> </SOAP-ENV:Body> 

  $server = new Server(); $server ->setClassmap($classMap->getClassMap()) ->setClass($handlerClassName) ->setObject($handler) ->setOptions(['features' => SOAP_SINGLE_ELEMENT_ARRAYS]) ;
