Newbie creating extension

Quick question all, I have succesfully created an extension for PHP and everything seems to work correctly, except I am unsure how to return a multi-dimensional array. I am currently returning a single dimension array fine, but I haven't found any documentation on how to create a multi-dimension array. One would think in the add_index_<whatever> functions that the index argument would allow this. Am I missing something? Please let me know. -=-=-=-=-=-=-=-=-=-=-=-=-=- Jason Woods Structus Technologies, Inc. jwoods@structus.com -- Webmail provided by ISLC http://www.islc.net
