Hackers target PHP web applications more often than other sites because most PHP code is written by developers with little security experience. Protecting web applications from these attacks has become an essential skill for all PHP developers. PHP: Creating Secure Websites shows you how to meet the most important security challenges when developing websites with PHP. Instructor Kevin Skoglund covers the techniques and PHP code needed to develop sites that are more secure, and to avoid common mistakes. Learn how to configure PHP properly and filter input and escape output. Then check out step-by-step defenses against the most common forms of attack, including cross-site scripting and SQL injection.

There are many great reasons to learn PHP. You can reduce manual updates to webpages, get user input, and connect to a database of products or other information. But some web designers are intimidated by the theory and jargon. PHP for Web Designers is different. Author David Powers provides a gentle introduction to PHP, through a series of simple exercises that help you develop fully functional dynamic webpages—all powered by PHP. Learn how to reduce website maintenance by moving common page elements to external server-side include files, change content automatically depending on the date or time, display alternate text, gather user input from a form, and link to a database to display product information. The final chapter is dedicated to understanding error messages and fixing their root causes. Note: This course was recorded with Adobe Dreamweaver, but you can use the code editor of your choice to follow along. Topics include: How to use PHP in a webpage Storing and displaying text and numbers in variables Using functions Adding comments to your PHP scripts Moving common page elements to include files Displaying different content on a page Working with multiple values in arrays and loops Getting form input sent by the POST method Using PHP sessions to preserve data Storing data in session variables Connecting to and querying a database Handling errors Apply for this course

Debug your PHP code efficiently with a variety of client and server-side tools. In this concise course for experienced PHP developers, author Jon Peck demonstrates how to leverage PHP's built-in tools, as well as the Xdebug and Firebug extensions, and FirePHP libraries to improve the quality of your code and reduce troubleshooting overhead. This course covers installation of Xdebug on Apache as well as working with the NetBeans IDE (integrated development environment). Jon then introduces native web browser developer tools for Firefox and Chrome, and demonstrates browser independent web debugging tools. Best practices for debugging and profiling web application failures and performance issues are also covered. Topics include: Configuring PHP error reporting Logging errors to file Gracefully handling fatal errors Installing Xdebug Understanding the principles of remote debugging Remote debugging with NetBeans Extending your browser with Firebug, FirePHP, or ChromePHP Apply for this course
