Fixes #1837: integrating Yii with different Software and libs

Integration with Yii1 included

Looks OK.

Do we really need to cover integrating Yii1 with Yii2?

[klimov-paul]

I suppose a lot of developers (including myself), which uses Yii1 may want to migrate old projects to Yii2. However such migration can not be made at once, so it would be common then at some stage project will use both Yii1 and Yii2.
It would be a shame if we do not provide any hint of how to integrate Yii2 with Yii1.

@klimov-paul

    "require": {
        "yiisoft/yii": "*",
        "yiisoft/yii2": "*",
    },

into composer.json, Integration done.

[samdark]

@creocoder except both provide Yii class.

why its not .md file?

[klimov-paul]

why its not .md file?

My mistake, fixed.

[Ragazzo]

Well, my opinion is that this article could be needed by some developers, because they will be searching for the way of how to reuse Yii1 code or make fast portable of extensions to not to wait while they will be adopted for Yii2. So it is better to have some official guide for this case, rather then just fixing bugs of different custom implementations. I think this should be linked to the article of the updating from Yii1 to Yii2.

[samdark]

@Ragazzo good idea.

+1 for covering Yii1 + Yii2

What needs to be done:

• should add note about composer.json to adjust like this:

"require": {
        "yiisoft/yii": "*",
        "yiisoft/yii2": "*",
    },

• also add link to the "Updating from yii1" guide page.

After that it's ready for merge imo.
