Question

What is difference between {iterate} and {foreach} in smarty tpl files?
are they different in using ‘from’ phrase?

Answer 1

As far as I know, there is no command called “iterate” in Smarty. There is, however, a command called {section} that is often confused with {foreach}.

From the documentation at Smarty.net:

The {foreach} loop can do everything a {section} loop can do, and has
a simpler and easier syntax. It is usually preferred over the
{section} loop.

Also:

{section} loops cannot loop over associative arrays, they must be
numerically indexed, and sequential (0,1,2,…). For associative
arrays, use the {foreach} loop.

Hopefully that helps.
