The presentation from Derick Rethans has been posted on his website - Migrating from PHP 4 to PHP 5.

The slides incldue topics such as the difference in the object models, creating objects inside it as well as comparing them. There are also changes to the way that $this works with your classes, and one thing I'm looking forward to - the "automagic" creation of objects.

Other topics covered in his presentation talk about signatures, the binaries that will be produced by PHP5, and a few changes in functions including: array_merge, strrpos, and stripos.

Looks like it was quite a speech - if anyone was there to hear it presented, leave a comment to let us know what you think...
