Create a service and put your common functionality in it. For example, you can name it ArrayService and register it in the container as array.service. You can then access this service from controllers via

创建一个服务并将您的公共功能放在其中。例如，您可以将其命名为ArrayService，并将其注册到容器中作为array.service。然后您可以通过控制器访问此服务。

$this->get('array.service');

and from commands via

从命令通过

$this->getContainer()->get('array.service');

So, your code will look something like this:

你的代码会是这样的:

$element = $this->get('array.service')->last($array); // or ->arrayLast($array)

If you need the same functionality across several projects, make a bundle with that service and add it to the deps file of each project. Then it will be installed when you run the bin/vendors install script.

如果您需要跨多个项目使用相同的功能，请使用该服务创建一个包，并将其添加到每个项目的deps文件中。然后，当您运行bin/vendor安装脚本时，它将被安装。

You can convert your functions to static methods of some class to make them autoloadable. Or... well... Place them where you want and require() from where you need them every time.

您可以将您的函数转换为某个类的静态方法，以使它们具有自动可读性。还是……嗯…将它们放在您想要的地方，并在每次需要它们的地方放置()。
