Array keys, values

If I have an array that looks like this:

Array
(
    [Salary] => Array
        (
            [0-50K] => Array
                (
                    [filterType] => range
                    [fieldLabel] => 0-50K
                    [fieldName] => SALARY
                    [lowerValue] => 0
                    [upperValue] => 50
                    [inclusive] => LEFT
                )

            [50-70K] => Array
                (
                    [filterType] => range
                    [fieldLabel] => 50-70K
                    [fieldName] => SALARY
                    [lowerValue] => 50
                    [upperValue] => 70
                    [inclusive] => BOTH
                )
        )
)


How can I access the key values?  Individually, that is. 
What about the
child array key/values?  Individually, that is.  In the
template, I've
tried:

{$myArray[0]}
{$myArray[0].filterType}
{$myArray[0][0]}

Nothing seems to work.  I know how to iterate through the
entire array and
display the contents that way, but I don't know how to get
the key/value of
just one particular element (and/or any child arrays of that
element).

Any help would be greatly appreciated!

thnx,
Christoph

{$myArray.Salary.0-50K.filterType} should work, but the key
0-50K might be
problematic due to the leading numeric character (I haven't
tried it).  If
it doesn't work, try adding a leading alpha char to those
key names.

And if I don't know the key value off hand because the array
was generated
dynamically?

As an aside, 2 features that would be really nice when
working with arrays
in a smarty template:

* get the total count of the elements w/o having to iterate
through the
array
* be able to access the first or last element even if the
keys aren't
numeric

thnx,
Christoph

You can get the count of an array with {$array|count}

But, you are better off assigning the count if you need it,
and also 
assigning your keys/index values that make things as simple
as possible 
in the template. Instead of assuming the template should be
able to 
traverse your data in any format, instead format your data
in a way that 
is a easy as possible to traverse and display.

Not very efficient but could do:

{foreach from=$my_array item=arr name=arr_loop}
   {if $smarty.foreach.arr_loop.first}
      do something for first only
   {/if}
{/foreach}

and (I forgot) {$my_array|end} to access the last
element. these two
expressions just use http://php.net/reset and http://php.net/end as
modifiers.

Where can I find out about this in the documentation?  I
don't see a
section  for something like this.  And when I did a search 
for 'count' in
the "english manual, the only thing that was returned
was a page for
 and the only reason that was returned is
because count was
used in a comment on that page.

But, you are better off assigning the count if you need it,
and also


But why would you assign it if there is another way to get
it?

thnx,
Christoph

It's in the modifiers section of the manual.
