但是必须要提一句，如果对项目来讲，兼容PHP5不是问题的话，最好还是使用PHP5。

But having said that, it is always a better idea to use PHP5 if compatibility is not an issue for the project.

有一个项目是要编译一个兼容服务器，实际上这与正式的服务器项目是不能比的，但是对于进行一些非正式的调试来说已经足够了。

There's a project to build a compatible server, which is not really comparable yet to the official server project, but might be enough for a bit of recreational debugging.

不过，拓宽的项目也可以收缩范围，不兼容的其它缺点可能抵销更广泛的开发利益。

However, projects that spread wider also can be stretched thinner, and advantages such as broader developer interest could be offset by incompatibilities other drawbacks.
