Symfony-通过服务容器传递ZipArchive（PHP核心类）类

Question

I need to pass ZipArchive class as a dependency for one of my class. I hope it is possible to do but no idea how to define in services.yml file.

Any idea please.

Answer 1

You can pass your ZipArchive class as service's argument

First, you need to create service for ZipArchive

services:
    lib.ziparchive:
        class: Lib\ZipArchive   #your ZipArchive Class Namespace

Then you can pass lib.ziparchive to your class service

    app.my_service:
        class: AppBundler\Services\MyService
        arguments: ['lib.ziparchive']

In your MyService Class, you need to create constructor.

namespace AppBundle\Services;

use Lib\ZipArchive

class MyService
{
    protected $ziparchive;

    public function __construct(ZipArchive $ziparchive)
    {
        $this->ziparchive = $ziparchive;
    }

}

Check more detail for service container

Hope it help.

Answer 2

I'd instantiate the core php object in the service construct and provide a setter to override this object (ie for testing later on):

services.yml:

app.my_service:
    class: AppBundler\Services\MyService

AppBundle\\Services\\MyService:

namespace AppBundle\Services;

class MyService
{
    protected $ziparchive;

    public function __construct()
    {
        $this->ziparchive = new ZipArchive();
    }

    public function setZipArchive(\ZipArchive $zipArchive)
    {
        $this->zipArchive = $zipArchive;

        return $this;
    }

}
