pear::soap array return problem

[Mike Evans <mike@public.arl.arizona.edu>]

Sorry, I'm new here and saw that there wasn't archives for the group... 
so accept my apologies if this has been covered before.

I'm building a Webservice with PEAR::SOAP and need to be able to return 
an unknown number of a particular result.  So far I have this in my Class:

$this->__typedef['{http://lifesci.ibsb.arizona.edu/}publication'] =
                  array('authors' => 'string',
        		'pub_date'=> 'string',
        		'title'	=> 'string',
        		'source'=> 'string',
        		'volume'=> 'string',
        		'pages'=> 'string'
                         );

$this->__dispatch_map['getPubs'] = array('in' => array('netid' => 			 
'string', 'publimit' => 'int'),
			'out' => array(	'publications' => 
'{http://lifesci.ibsb.arizona.edu/}publications' ));

The problem is, I'm not sure how many publications will be returned from 
the getPubs() method.  Any tips on I can handle this?

Thanks.
