On the KillerPHP blog Stefan Mischook shares a sample chapter from a recent PHP-related book published by Packt, "PHP 5 CMS Framework Development":
The people at Packt Publishing just sent me a free sample chapter (in PDF format) of their latest PHP book (PHP5 CMS Framework Development) for me to pass on to you guys.
The sample chapter looks at access control in a CMS application. Stefan also includes a brief outline of the contents of the remainder of the book. Other chapters cover topics like decreasing code bloat, security, specialized handlers and localization.
