PSR-4目录结构和命名空间是否具有一组功能? [英] PSR-4 directory structure and namespacing for a set of functions?

问题描述

我有一些有用的PHP函数.我想为他们创建一个符合PSR-4的存储库，但是我发现了这些指南( 1 ， 2 ，

I have a set of PHP functions that I find useful. I want to create a PSR-4 compliant repository for them, but the guides I have found (1,2,3) seem to talk only about classes for autoloading.

例如，我的文件如下，每个文件具有一个功能:

For instance, my files are as follows, with one function per file:

my_cool_function1.php
my_cool_function2.php
... etc.

如何从它们创建符合PSR-4的库?

How can I create a PSR-4 compliant library from them?

推荐答案

无法找到非类的PSR-4自动加载文件的任何文档的原因，这是因为

The reason you're not able to find any documentation for PSR-4 autoloading files which aren't classes, that's because as the specification states - it's designed for autoloading classes.

直接取自官方规格:

此PSR描述了从文件路径自动加载类的规范.它是完全可互操作的，并且除包括PSR-0的任何其他自动加载规范外，还可以使用.该PSR还描述了根据规范自动放置文件的位置.

This PSR describes a specification for autoloading classes from file paths. It is fully interoperable, and can be used in addition to any other autoloading specification, including PSR-0. This PSR also describes where to place files that will be autoloaded according to the specification.

更具体地说；

术语"类"是指类，接口，特征和其他相似结构.

The term "class" refers to classes, interfaces, traits, and other similar structures.

具有功能的文件实际上不是相似的结构.

A file with functions isn't really a similar structure.

要自动加载这些文件，您需要使用files自动加载:

To autoload those files, you'll need to autoload using files:

"autoload": {
    "files": [
        "src/my_cool_function1.php",
        "src/my_cool_function2.php"
    ],
    "psr-4": {
        "SomeNamespace\\": "src/YourNamespace/"
    }
}

您会发现，psr-4规范通常会映射到名称空间.

You'll notice from this, that the psr-4 spec maps (usually) to a namespace.
