PHP 5.4 - A Major Update
Found on I Programmer on Sunday, 04 March 2012
PHP 5.4 brings improvements in memory management and performance, which in turn will make it faster, a built-in webserver for testing purposes, and features that had been destined for PHP 6.0.
Another important change is that Magic Quotes, a features that was supposed to improve security by preventing SQL Injection but in fact was notoriously insecure and had already been deprecated is finally removed. Other deprecated features have also been removed to provide a cleaner code base.
It will be interesting to see how many will blindly update their install without checking the release notes and changelog before doing so and then whine about all the problems the update causes.
