There are two ways to determine whether an array is empty in smarty templates. Below are examples.
(1) Use php count function
{if $array|@count gt 0}
... ...
{/if}
(2) This way of writing is very strange. Today I searched online because the first method didn’t work, and I found the following strange way of writing.
{if count($array) gt 0}
... ...
{/if}
