Re: Passing array names into a function

Brian Thanks for the response, but unless I am misunderstanding, I don't think this is what I am after. Just to restate, I want to set up a module as a static data cache. The main function $my_cache will have a static array $data. There will be a set of helper functions to set values into $data, get values from $data, lock values, mark them as dirty etc. Calling functions will be able to store and manage values in the cache for other functions to access. I need to be able to pass an array addresse of n dimensions into $my_cache together with a value, and an action such as "set", "get", "unset" etc: $my_cache( "set", "['key1']['key2']" , "someval" ) ; Then somehow, inside $my_cache, I need to assign the value to $data as follows: $data"['key1']['key2'] = "someval" ; As I say, I have been mucking about with eval( ) and variable variables with no success. Guess I am having a bad brain day. Any help much appreciated - its getting late here and I am running out inspiration.... Thanks again Geoff Caplan
