Use PHP in a File That Supports Mixed Scripting Languages

You already know how to start and finish a PHP file using regular methods. The code below shows the common way of creating a PHP file:

<?php
echo "Hello About.com!";
?>

What you might not know is that you can run this same bit of code using the script tag:

<script language = "php">
echo "Hello About.com!";
</script>

The script tags can identify a language (PHP or otherwise) who's code you will be running in a section. This is useful in a file that allows for mixed scripting languages. While it is not a common setup, it is sometimes used. By using the script tags, you can easily identify what language is where, and when it switches.
