What’s new in PHP 5.3

Filed under

In my previous post I mentioned that PHP 5.3 will be released in early 2008 so I think it’s just in time to talk about the features of this version. It is started by this polling (in detail, in an ordered version) on the internal list. The big gun features are namespaces, late static binding and mysqlnd, but there are other interesting improvements, for example __callStatic, dynamic static calls. In this part of this series we are going to analyze namespaces in detail.


Namespace support in PHP was a long-felt want feature. In PHP the main motivation behind adding namespace support to the language was to solve the problem of long class names. If you develop a bigger library, you have to use long class names to avoid naming conflicts, for example look at this monster: Zend_Search_Lucene_Analysis_Analyzer_Common_Text_CaseInsensitive.

From the version 5.3 you can group your code into namespaces. Different namespaces can contains classes, functions, constants with the same name. Defining a namespace is very straightforward, you should use the namespace statement in the very beginning of the file, for example:

part 1: namespaces

part 2: late static binding

part 3: mysqlnd

part 4: __callStatic, OpenID support, user.ini, XSLT profiling and more

Curious about Linux? Try Linux Desktop on the Cloud

Linux maintains a very small market share as a desktop operating system. Current surveys estimate its share to be a mere 2%; contrast that with the various strains (no pun intended) of Windows which total nearly 90% of the desktop market. For Linux to challenge Microsoft's monopoly on the desktop, there needs to be a simple way of learning about this different operating system. And it would be naive to believe a typical Windows user is going to buy a second machine, tinker with partitioning a hard disk to set up a multi-boot system, or just jump ship to Linux without an easy way back.
