Hello,

If I have an array made up of a bunch of key => value pairs, how can I
pass the values of each key as an argument to a function, given that
the number of items in the array are not static (i.e: sometimes
there's one item, sometimes there's two)?

For example, if I have the following array:

$list = array('sky' => 'blue', 'grass' => 'green');
$list = array_values($list);

I'd like to pass the two values in $list to a function that has two
arguments, i.e:

function color($sky, $grass) { }

The trick is is that $list will not always contain two items -
sometimes one, three, four, etc, so it has to pass them dynamically to
the function. I know about call_user_func(), and how I can pass
parameters to it, but I'm having a difficult time trying to pass
multiple parameters given that I don't know how many I need to pass.

Can anyone help?

Rob
