There's more than one issue here.这里的问题不止一个。

composer.json (package) composer.json（包）

In your composer file (for the Pagination library), change PSR-0 to PSR-4 .在您的作曲家文件（用于分页库）中，将PSR-0更改为PSR-4 。 PSR-0 is an old format that was deprecated around 5 years ago (2014). PSR-0是一种旧格式，大约在 5 年前（2014 年）被弃用。

You should also always end the namespace with \\ .您还应该始终以\\结束命名空间。 So the package should be:所以 package 应该是：

"autoload" : {
    "psr-4" : {
        "Pagination\\" : "src/"
    }
},

Namespaces命名空间

Since you're namespace is Pagination\ , that's the namespace you should use in the code that uses it.由于您的命名空间是Pagination\ ，因此您应该在使用它的代码中使用该命名空间。

So if you have a class with:因此，如果您有一个 class ：

namespace Pagination;

class Pagination {
    ...
}

then your use statement should simply be:那么你的use语句应该是：

use Pagination\Pagination;

The shorif2000 is the vendor name (which is only for composer to be able to group packages on vendor name and to remove the risk of different packages overwriting each other. shorif2000是供应商名称（仅用于作曲家能够根据供应商名称对包进行分组并消除不同包相互覆盖的风险。
