On DZone.com today Giorgio Sironi has posted the results of a poll taken a little while back concerning what people thought was the best feature of the upcoming PHP 5.4 release.
After two weeks, we have closed the poll among the PHP community of Web Builder Zone to establish which are the most wanted features, which will influence development of applications on PHP 5.4. Hopefully this poll would also shape our focus in tutorials in the future - I personally plan to dedicate more time to the winning features.
Runners up included the removal of magic quotes and strict mode with the top three being (in this order) the upload progress patch, traits and the array improvements leading the pack. You can see the results here.
