What is the difference between includes and frames in PHP, and how does it affect link behavior?

The main difference between includes and frames in PHP is that includes allow you to include the content of a file within another file, while frames allow you to display multiple web pages within a single web page. When using includes, the link behavior will remain within the same page, as the content is simply included within the current page. On the other hand, when using frames, the link behavior will change as the links will navigate within the frame where they are clicked. 

<!-- Using includes to include content from another file -->
<?php
include 'header.php';
?>
<p>Main content goes here</p>
<?php
include 'footer.php';
?>

<!-- Using frames to display multiple web pages within a single web page -->
<frameset cols="25%,75%">
  <frame src="menu.php">
  <frame src="content.php">
</frameset>
