This title helps LAMP professionals take their skills to the next level with in-depth discussions of OOP; extensions of PHP such as PEAR, GD, XML, and CURL; improving site security; and, advanced tools available to the coder. Those proficient in other languages such as Java, C++, Perl and ASP will find this guide invaluable when transitioning to the LAMP environment. The Web site includes sample scripts created in the course of each chapter, and several applications that can be modified and reused.
