a basic array question!

feel kind of foolish posting this.. but i can't seem to figure it out for now.. i have an array, i can do a print_r($foo) and get the following: Array ( [bookmark] => 1 [facets] => Array ( [0] => Array ( [lastname] => <form id="facet-lastname"> <input type="hidden" name="list" value="" /> <input type="hidden" name="offset" value="0" /> <input type="hidden" name="orderBy" value="username" /> <input type="hidden" name="sort" value="asc" /> <strong>Name:</strong> <input type="text" name="_lastname" value="" style="width: 125px" /> <input type="submit" value="Search" /> </form> } i simply need to know how to get the actual value of an element ('lastname') to do: $cat = $foo->facets[0]->['lastname'] (obviously, this doesn't work!!) i've tried a variety of possible choices, with no luck... any ideas/thoughts/etc... thanks bruce bedouglas@earthlink.net
