1. capture captures a piece of content but does not output

Syntax:

{Capture name = 'var '}

3. foreach and foreachelse are used to traverse arrays.

Syntax:

{Foreach from = array key = key name = name item = content}

{Foreachelse} when the array to be traversed does not have any elements, run the statement following foreachelse.

{/Foreach}

From: array to be traversed

Item: The Retrieved key value.

Key: The name of the retrieved Key.
