How to assign an array within a smarty template file?

In a Smarty template file, you can assign an array to a variable using the assign function. The first parameter is the variable name, and the second parameter is the array.

Example:

{assign var='my_array' value=$my_array}

You can also use a Smarty variable as an array key, like this:

{assign var='my_array' value=array($my_key => $my_value)}

You can also use the $smarty.foreach loop to iterate over the array and print its values

{foreach from=$my_array item=val}
    {$val}
{/foreach}
