Is this what you're looking for? (sorry so messy; in a hurry)

?php

$my_array = array('foo' = array('bar' = 'baz'));
$my_var = 'peanuts';

print brBefore:  . $my_array[foo][bar];
print brBefore:  . $my_var;

function data_store($action, $variable, $value )
{
   if($action == 'set')
  return $variable = $value;
}

data_store('set',$my_array[foo][bar],'ack');
data_store('set',$my_var,'peanut butter');

print brAfter:  . $my_array[foo][bar];
print brAfter:  . $my_var;

?

Re: [PHP] 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

Hi folks

 {
  // set my new value
 }
}
