How to insert a shortcode into a file?

Question

WordPress

You need to integrate the short code into the page, but you need to do it specifically in the php file. How to do it?
I tried just pasting it, but then it just comes out as text.

Answer 1

do_shortcode

<?php
  echo do_shortcode(... );
?>

For example for Contact form 7:

<?php
  echo do_shortcode(
    '[contact-form-7 id="11" title="Contact Form 7"]'
  );
?>
