Either run ``` php composer.phar require --prefer-dist laxity7/yii2-collection ``` or add ``` "laxity7/yii2-collection": "~1.0.0" ``` to the require section of your composer.json. \##Basic usage Collection is a container for a set of items. It provides methods for transforming and filtering the items as well as sorting methods, which can be applied using a chained interface. All these operations will return a new collection containing the modified data keeping the original collection as it was as long as containing objects state is not changed. ``` $collection = new Collection([1, 2, 3]); echo $collection->map(function($i) { // [2, 3, 4] return $i + 1; })->filter(function($i) { // [2, 3] return $i < 4; })->sum(); // 5 ``` The collection implements \[\[ArrayAccess\]\], \[\[Iterator\]\], and \[\[Countable\]\], so you can access it in the same way you use a PHP array. A collection however is read-only, you can not manipulate single items. ``` $collection = new Collection([1, 2, 3]); echo $collection[1]; // 2 foreach($collection as $item) { echo $item . ' '; } // will print 1 2 3 ``` Configuration for ActiveRecord ------------------------------ [](#configuration-for-activerecord) To use this extension, you have to attach the `yii\collection\CollectionBehavior` to the `ActiveQuery` instance of your `ActiveRecord` classes by overriding the `find()` method: ``` /** * {@inheritdoc} * @return \yii\db\ActiveQuery|\yii\collection\CollectionBehavior */ public static function find() { $query = parent::find(); $query->attachBehavior('collection', \yii\collection\CollectionBehavior::class); return $query; } ``` ### Health Score 29 — LowBetter than 57% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity17 Limited adoption so far Community14 Small or concentrated contributor base Maturity55 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
