 Usually, when you want the output produced by that file printed multiple
times.

stuff.php:
<?php print "The value is: $var<br>"; ?>

index.php:
<?php
$var = 1;
include('stuff.php');

$var = 2;
include('stuff.php');

$var = 3;
include('stuff.php');
?>

 This is a contrived example, but sometimes it's what you want.
