smarty question - if construct

Question

PHP

Good day. Sorry if this is a dumb question, I just don't understand it well.
There is a site with templates, smarty is used. I have written a function that replaces {free} in the template with one.
I need to do something to make it If 1 - then something, if not - something else.
Well, roughly speaking, you need to display different content depending on this unit.

Answer 2

{if $i==10}

{else:}
   Не равно 10
{/if}
