Are there any best practices for handling echoing of variables in Smarty to avoid displaying arrays unintentionally?

When echoing variables in Smarty, it's important to be cautious of unintentionally displaying arrays. To avoid this issue, you can use the `is_array` function in Smarty to check if the variable is an array before attempting to display it. If it is an array, you can handle it appropriately, such as looping through the array elements to display them individually.

{if is_array($variable)}
    {foreach $variable as $value}
        {$value}
    {/foreach}
{else}
    {$variable}
{/if}
