cases • Example: • xsd:long is mapped to PHP int, overflows on 32bit archs • Needs two callbacks: • one for XML->PHP conversion • one for PHP->XML conversion

name="parameters" type="apache‐enc:Map" /> </xsd:complexType> </xsd:schema> • Custom Apache Axis encoding style • be aware that it won’t offer good interoperability • Use any type for values, scalars for keys • Keys and values will use RPC encoding in the message
without a response declared • Both SoapClient and SoapServer will close the connection as soon as they can when calling such a method http://flic.kr/99996581@N00/1122331674/
be validated against the WSDL’s XML Schema • Unlike with RPC style services, such messages won’t contain the name of the called method anymore • Solution: wrap the message payload in an element that has the same name as the procedure you want to call • Not a problem in PHP, but you need to wrap/unwrap yourself

some information about the service in WSDL format • WSDL auto-generated by the Routing • Requires basic knowledge of XML Schema and WSDL • Supports Document/Literal Wrapped for Servers
