A question was asked in the comments for "Make Your Own Ajax Contact Form" about preventing a PHP script from being accessed directly.

Have you ever thought of an idea to do something with PHP, and wanted to test it out? You probably have to go through the trouble of writing your script, starting a server, and testing it in your browser.
Perhaps you love using PHP, and would like to do more than web development with it. You might like it as a more readable version of Perl.
