Converting a PHP array to a SOAP structure

Question

I'm picking up an old project that uses SOAP and WSDL, something that I'm not too familiar with. I have the following data structure defined in the WSDL (simplified in this example):

<s:complexType name="RequestPayment">
    <s:sequence>
        <s:element minOccurs="0" name="ProviderData" type="s0:ArrayOfFieldPairOfNameString"/>
    </s:sequence>
    <s:attribute name="CancelURL" type="s:string"/>
    <s:attribute name="ReturnURL" type="s:string"/>
</s:complexType>
<s:complexType name="ArrayOfFieldPairOfNameString">
    <s:sequence>
        <s:element maxOccurs="unbounded" minOccurs="0" name="Field" nillable="true" type="s0:PairOfNameString"/>
    </s:sequence>
</s:complexType>
<s:complexType name="PairOfNameString">
    <s:simpleContent>
        <s:extension base="s:string">
            <s:attribute name="Name" type="s:string" use="required"/>
        </s:extension>
    </s:simpleContent>
</s:complexType>

The project is using nusoap, a portion of my PHP looks like:

$payment['ProviderData'] = array(
    'Field' => array(
        'Name' => 'Foo',
    ),
);

Which is able to produce the following (again, simplified here):

<payment>
    <ProviderData>
        <Field Name="Foo" />
    </ProviderData>
</payment>

I'm not sure what format my PHP array should be in, in order to produce XML that looks like the following:

<payment>
    <ProviderData>
        <Field Name="name 1">value 1</Field>
        <Field Name="name 10">value 10</Field>
        <Field Name="name 2">value 2</Field>
    </ProviderData>
</payment>

I've tried setting a key called Value, !Value, and other variations, without success.

Any help would be appreciated. Thanks.

After working backwards (converting the XML example into PHP), the format you want is:

$payment['ProviderData'] = array(
   'Field' => array (
     0 =>
     array (
       '!Name' => 'Foo',
       '!' => 'Bar',
     ),
     1 =>
     array (
       '!Name' => 'Amount',
       '!' => '98',
     ),
   )
);
