On PHPBuilder.com, there's a new tutorial, an excerpt from the APress book "Pro PHP Security" by Chris Snyder and Michael Southwell talking about how to prevent SQL injections in your web applications.

They take a complete look at SQL injections, including:

• What SQL injections are
• How they work
• Why it's an issue with PHP
• The types of user input

This is just the first part in the series, so stay tuned for even more great security content from the new APress book.
