Can't you use

int iterator_count ( Traversable $iterator )

http://php.net/manual/en/function.iterator-count.php

?

What do you get instead?

Additional info

The current implementation of GeneratorCollection supports functions like filter and map.

Doing something like I've proposed here: nikic/iter#45
Would allow for a fluent interface allowing code like

$collection->filter(...)->map(....)->...

Yii 2 requires PHP 5.4, but this requires at least 5.5, I'd suggest, if you are using a stricter requirement than Yii 2 anyway, to just go with 7.0 or 7.1. (Since that is where Yii 2.1 will go as well)

Right now basic CRUD for model looks like this:

    public function actionCreate()
    {
        $model = new User();

        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            return $this->redirect(['view', 'id' => $model->id]);
        } else {
            return $this->render('create', [
                'model' => $model,
            ]);
        }
    }

    public function actionUpdate($id)
    {
        $model = $this->findModel($id);

        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            return $this->redirect(['view', 'id' => $model->id]);
        } else {
            return $this->render('update', [
                'model' => $model,
            ]);
        }
    }

    public function actionDelete($id)
    {
        $this->findModel($id)->delete();

        return $this->redirect(['index']);
    }

When we need to work with tabular input and handle multiple instances of the same model in single request, things get more complicated (and still there is no docs for it).

ModelCollection could provide wrappers that makes this similar to CRUD for single model:

    public function actionCreate()
    {
        $collection = (new PostCollection())->fill(Post::className(), 10);

        if ($collection->load(Yii::$app->request->post()) && $collection->save()) {
            return $this->redirect(['index']);
        } else {
            return $this->render('create', [
                'collection' => $collection,
            ]);
        }
    }

    public function actionUpdate($ids)
    {
        /* @var $collection PostCollection */
        $collection = $this->findModels($ids);

        if ($collection->load(Yii::$app->request->post()) && $collection->save()) {
            return $this->redirect(['index']);
        } else {
            return $this->render('update', [
                'collection' => $collection,
            ]);
        }
    }

    public function actionDelete($ids)
    {
        $this->findModels($ids)->delete();

        return $this->redirect(['index']);
    }

Basic project infastructure should be setup, allowing early access and contributing.
Following action should be performed:

• setup 'yiisoft/yii2-collection' project at packagist.org
• setup GitHub hook for 'packagist.org' package synchronization
• setup project build on Travis
• setup GitHub hook for 'Travis' automatic build for main branches and pull requests
