Is there a neat way to test if an array is empty?

I'm trying to make a heading not appear if an array of fetched items doesn't contain any items.

I realise that you could run a foreach loop and then do a has_content test on the first item, but this seems clumsy - is this the only way?

Hi Paul,

You can test it with count() tpl operator

{* Example 1 *}
{def $my_array=array()}

{if $my_array|count()}

{else}

{/if}

{* Example 2 *}

{if $my_array|count()|gt(0)}

{else}

{/if}

Hope that helps.

Doesn't empty arrays evaluate to false ??
like this:

{if $my_array}
{else}
{/if}
