Re: array indexes as arguments to a function

I don't understand what you're asking. If you want to return a portion of an array, simple return the element holding it. In your example: POST["var1_arr"]["dim1"]["dim2"] return var1_arr; Will return whatever lives in var1_arr. Have a play around, you can see what a variable contains using print_r() "Dennis Gearon" <gearond@fireserve.net> wrote in message news:40F306F9.504@fireserve.net... > please CC me, as I am on digest. > ------------------------------------------------------------------- > say I've got a class that stores the cookie/get/post vars. > I want to retrieve say one of them. > Say, that post vars come back from browser as: > > POST["var1_arr"]["dim1"]["dim2"] > > they are stored in > > object->post_vars["var1_arr"]["dim1"]["dim2"]; > object->post_vars["singleton"]; > > I have the function > > class->get_post_var($index_arr){ > return correct, processed post var; > } > > > How can I get the function to return an arbitrary depth into the post > vars array? > i.e. EITHER > > return $this->class_user_input_processing_function( > $this->post_vars, $index_arr); > > Where $index_arr contains either: > > $index_arr = array("var1_arr","dim1_value", "dim2_value"); > -or- > $index_arr = array("singleton");
