Web Services for PHP

• Use Objects with SOAP for all the same reasons you would normally use Objects

• Client will serialize objects sent and received

• Server will serialize objects sent and recieved

• PEAR::SOAP treats XML Schema Complex Types as Objects

• Constructors are not used, members are set directly

• Overload could be used to provide setters and getters

Schema defining SOAPStruct

<schema xmlns="http://www.w3.org/2001/XMLSchema" 
    targetNamespace="http://soapinterop.org/xsd">
    <complexType name="SOAPStruct">
        <all>
            <element name="varString" type="string"/>
            <element name="varInt" type="int"/>
            <element name="varFloat" type="float"/>
        </all>
    </complexType>
</schema>
