SoapClient->MyAction($params), Formatting the $params array - php

Question

I'm using PHP SoapClient() to consume a web service.
$sc = new SoapClient($uri);
$sc->MyAction($params);
$params would be an array to create the XML below, but I'm unsure how to format the array where there are multiple OrderLine keys.
<args>
<OrderLines>
<OrderLine>
<LineNumber>1</LineNumber>
<Product>Acme Foos</Product>
<Description>Bars and Bazzes</Description>
<Quantity>1</Quantity>
<Price>5.00</Price>
</OrderLine>
<OrderLine>
<LineNumber>2</LineNumber>
<Product>Kittens</Product>
<Description>Very sleepy</Description>
<Quantity>1</Quantity>
<Price>12.00</Price>
</OrderLine>
</OrderLines>
</args>
This is a dump of the array format I'm sending in, unsuccessfully because I'm not sure how to make the array with multiple OrderLine keys.
[args] => Array
(
[OrderLines] => Array
(
[0] => Array
(
[LineNumber] => 1
[Product] => 'Acme Foos'
[Description] => 'Bars and Bazzes'
[Quantity] => 1
[Price] => 5.00
)
[1] => Array
(
[LineNumber] => 2
[Product] => 'Kittens'
[Description] => 'Very sleepy'
[Quantity] => 1
[Price] => 12.00
)
)
)
When sending this to the web service, I am getting the following SoapFault exception:
Server was unable to read request. ---> There is an error in XML
document (2, 1001). ---> Input string was not in a correct format.

Answer 1

This example is correct. The error was not related to the array. It was some other invalid data in my params.
