Quick PHP Variable Substitution Example

Here is a quick example of PHP variable substitution:

<?php echo 2 + 2;
  $myname = 'Perry';
?>
		
<h1>This page is all about <?php echo $myname ?></h1>
<?php echo 5 * 5 ?>
<h2>All About <?php echo $myname ?></h2>

The above code snippet assigns ‘Perry’ to the variable $myname, and then uses that variable in the h1 and h2 heading lines.
