Inserting a PHP Variable into HTML Code

Suppose now we have a paragraph, above which a PHP variable is defined:

html<?php
  $str = 'text';
?>
<p>text</p>

We can insert our variable inside the paragraph:

html<?php
  $str = 'text';
?>
<p><?php echo $str; ?></p>

Or we can simplify the variable insertion using a short PHP tag:

html<?php
  $str = 'text';
?>
<p><?= $str ?></p>

Also, three paragraphs are given:

Insert the text of the variables into the corresponding paragraphs.
