Php 有什么最佳实践可以实例化一组类吗？

我正在制作一个小PHP软件，为了运行它，需要实例化一组类，如下所示：

$database          = new Database; //handle some kind of CRUD
$someFunctions     = new SomeFunction($database); //injecting the CRUD
$someMoreFunctions = new SomeMoreFunctions($database, someFunctions);
$evenMoreFunctions = new EvenMoreFunctions($database);
$app               = new AppManager($someFunctions, someMoreFunctions, evenMoreFunctions);
.............

$app->oneFunction()->doSomething->doSomeMore(); //working with the app

$app = App::oneFunction($maybeARecordId);
$app->doSomething();
$app->doSomeMore();
$app->maybeASaveFunction();

我最终必须将所有类的实例化放在一个单独的文件或类中，以包括或实例化。目标是使所有实例化对使用应用程序的开发人员透明

我认为最好的方法是用户只需做如下操作：

$database          = new Database; //handle some kind of CRUD
$someFunctions     = new SomeFunction($database); //injecting the CRUD
$someMoreFunctions = new SomeMoreFunctions($database, someFunctions);
$evenMoreFunctions = new EvenMoreFunctions($database);
$app               = new AppManager($someFunctions, someMoreFunctions, evenMoreFunctions);
.............

$app->oneFunction()->doSomething->doSomeMore(); //working with the app

$app = App::oneFunction($maybeARecordId);
$app->doSomething();
$app->doSomeMore();
$app->maybeASaveFunction();

有没有关于如何做到这一点的最佳实践

谢谢。

您正在寻找的术语称为“依赖注入容器”或DIC。它将使用集合绑定为您创建实例。谢谢。这个概念对我来说是新的，我得读一读。
