PHP动态名称空间 [英] PHP dynamic namespaces

问题描述

我需要能够做到这一点:

I need to be able to do this:

$ns = "\\common\\components\\cfoBi\\i18n\\{$countryCode}\\gimmea";
use $USP;

显然这行不通.那我该怎么办呢?有动态名称空间"吗?

Obviously this won't work. So how can I do this? Have "dynamic namespaces"?

推荐答案

不可能.命名空间，导入和别名在编译时解析.

Not possible. Namespaces, imports and aliases are resolved at compile time.

但是，可以通过在运行时建立的类名称来创建对象:

However, it is possible to create objects from a class name that is built at runtime:

$className = "common\\components\\cfoBi\\i18n\\{$countryCode}\\gimmea";

$object = new $className();
