John Lebensold has recorded a VERY nice 7 part video run through that shows how you can use some of the new functionality in PHP 5.30+ that I highly recommend everyone doing any kind of PHP development to watch especially if you are working with any type of objects, relations, models or always wanted to learn howto!

If after watching the videos (should play in one go above) you dont see how life will be made a lot simpler, please comment!
