PHP 5.4 is here!

Before you start thinking about upgrading your server, you should know if it’s worth doing it.

YES!

According to Nettuts+, “the latest enhancements significantly improve its elegance, while removing deprecated functionality, resulting in a dramatic optimization of the runtime (up to 20% more speed and memory usage reduction).”

20%?

I like the sound of that!

That could effect those on the verge of needing a server upgrade.

Here are a couple other things you may be happy to see:

• Traits
• Built-in web server for dev purposes
• Shorter array syntax
• Array dereferencing
• $this in anonymous functions
• <?= is always on <— THIS!
• More!

Learn more about the new features, over 100 bugfixes and download PHP 5.4.0. on the PHP website.

I also recommend reading Nettuts+ post on everything you must know about PHP 5.4.
