One of my old Internet friends Brad made a very nice online slide that introduces to you some of the exciting new features of PHP 5.3. I’m most interested in namespace that would make coding in a large project and code reuse much easier, especially for people who find keeping naming conventions a challenge in the team.
Here’s the original post and slide: http://bradley-holt.com/2010/11/new-features-in-php-53/
All the new stuff and concepts are presented in a practical manner that’s extremely straightforward. Programmers should find them a breeze to crunch.
