Can't able to display the OLAP reports using PHP client

I want to load the all the reports from the Jasper Server on my php processmaker application. I am able to create a plugin by using the PHP Client provided by the Jaspersoft Community which is showing all the reports except the olap. I am using the api

http://community.jaspersoft.com/project/php-client

But this api does not giving me the listing of the olap reports. Is there any other way to display all those reports in my own site? Please help.
