If you get this error:
Fatal error: Cannot use object of type stdClass as array
when trying to read the result as an array, use this function.

function objectToArray( $object )
{
if( !is_object( $object ) && !is_array( $object ) )
{
return $object;
}
if( is_object( $object ) )
{
$object = get_object_vars( $object );
}
return array_map( ‘objectToArray’, $object );
}
this will convert the object returned by soap api to an array.
