Using a variable as array index

Question

I have a smarty variable which stores an associative array. Is there a way to combine a string and another smarty variable to create the index?

Example: The array element I want to print is $foo['index1'] and the variable $count = 1. I tried to print the value using $foo.index$count but that results in a smarty syntax error (unrecognized tag).

If you have something like this in PHP:

$foo['index1'] = 'aaa';
$smarty->assign('foo', $foo);
$smarty->assign('count', 1);

Then you should do in smarty:

{assign var = "idx" value = "index"|cat:$count}
{$foo[$idx]}

Like this you can get the index count in foreach:

{foreach from=$value item=foo key=k name=myloop}                                
{assign var=op value=$smarty.foreach.myloop.index}
index count:{$op}
{/foreach}
