比较受关注的特性有：namespaces、late static binding、closures（我曾经写过一篇相关的blog）、garbage collection。

新的扩展包括：ext/phar、ext/intl 和 ext/fileinfo 等等。

There are three kinds of services that are commonly associated with the cloud: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Software as a Service has gotten a lot of good press in the past few years, as Salesforce and the like have seen adoption from the smallest shops to the largest corporations. Beyond a few web service API’s, however, SaaS doesn’t offer much for application developers. Platform as a Service, on the other hand, provides full-service hosting environments that can automatically allocate resources as your applications need them. Google App Engine, for example, supports sandboxed Python and Java environments (PHP is the most requested feature, and hasn’t been ruled out by the GAE team). PaaS environments often extend a SaaS offering, as is the case with SugarCRM’s certified modules. But PaaS has some big shortcomings: your applications are far from portable and are limited to what the vendors specifically permit them to do. Infrastructure as a Service is less confining. Your applications can use these services to scale with the same hardware that backs the largest sites on the web. You can usually install the OS of your choice and run your applications in environments tailored to their needs. The tradeoff is that you have to provision additional resources manually to handle spikes in load, and you must design your applications differently if you’d like to use the services that improve the scalability of your app. As we’ll see later, changing your mindset to take advantage of these services isn’t necessarily a bad thing…
