为什么是PHP所有系统都在全局命名空间中运行？
这不会导致混乱，因为添加了新功能，其名称与用户定义的功能相冲突？
简单：不要使用php函数作为你自己的名字。这将与任何语言冲突
！

我在谈论添加到PHP的新函数。
避免那些显然需要预知。
我很少看到用户功能进入如此拥挤的命名空间 -
选择功能名称感觉有点像导航雷区。
这会以任何语言冲突！
其他语言不能将所有功能直接放入全局命名空间。

我认为这个问题更多地与事实名称空间arn''ta功能
of PHP有关。它们将包含在PHP5中。

Why are PHP''s system functions all in a global namespace?
Won''t this lead to chaos as new functions are added, which have names
which clash with user-defined functions?

simple : do not use php functions as your own names. this would conflict
in ANY language!

I was talking about new functions added to PHP.
Avoiding those would apparently require precognition.
Rarely have I seen user functions going into such a crowded namespace -
picking function names feels a bit like navigating a minefield.
this would conflict in ANY language!
Other languages don''t put all their functions straight into a global namespace.

I think this issue has more to do with the fact namespaces arn''t a feature
of PHP. They will be included in PHP5.
