php.net有一个张贴的纪录关于手册重新组织：‘A few weeks ago the manual was restructured to improve navigation and make room for per-extension chapters and usage examples along with improved documentation for object oriented extensions.’
这些改变包括函式的参阅、预先定义的变数以及前后文的选项参数，还有namespaces、 late static bindings 及 Phar (这些将在PHP 5.3含括入)，现在手册的授权方式改为 CreativeCommons Attribution license。
突然改了排版，感觉有点不习惯，还有常看到这种授权方式，有空再进一步了解！
