I'm new to nusoap and have successfully connected to the server that is providing data to me. The data is returned into $result, but I don't know how to access the various elements of this array, and the structure is more complex than many of the examples that I've found, causing me a good deal of trouble.

How do I take the resulting arrays that follow and print out the content of the Category array in very simple form (for example as ID/Category/Description)? The following array is what is returned and printed out using print_r($result);

Any help is greatly appreciated.

There's probably a better way to do it, but this seems to work:

$first = $result['getCreditCardCategoriesResult'];
$categories = $first['Categories'];
$items = $categories['Category'];

and then I can loop through $ items to print out each of the desired array elements:

foreach ($items as $i) {

<td><font size="-1"><b><? echo $i['Category']; ?></b><td><? echo $i['ID']; ?></td><td><? echo $i['Description']; ?>

}

I have the results printing out into a table just to see if they come out right, which they do. I'm new to PHP and brand new to nusoap, so I justed wanted to see if I could make it work and output data in usable form. Now that I've seen that I can do it, the wheels in my head are spinning. This is pretty cool.
