Installation ============ [](#installation) ``` $ composer require enzyme/collection ``` Usage ===== [](#usage) You can create a collection from a standard PHP array. Once you have a collection, you can make use of all the methods it exposes. ``` use Acme\Mailer; use Enzyme\Collection\Collection; $users = new Collection(['John123', 'Jane456', 'Harry789']); // Send each user an email. $users->each(function ($user) { Mailer::sendWelcomeEmail($user); }); ``` The collection implements `ArrayAccess`, `Iterator` and `Countable`, so you can use it as a standard array. ``` use Enzyme\Collection\Collection; $users = new Collection(['John123', 'Jane456', 'Harry789']); var_dump($users[0]); // 'John123' ``` In the example above, the equivalent and much more readable method would be `$collection->first()`. Available methods ================= [](#available-methods) Method signatureDescription`count()`Return the number of elements in the collection.`each(Closure $fn)`Execute the callback function provided on each item in the collection. The callback function is passed `$value, $key` as arguments. If the callback returns `false`, the function will return early and will not continue iterating over the remaining items left in the collection.`except(array $keys)`Return a new collection containing all the keys in the current collection except those whose keys match the ones provided.`filter(Closure $fn)`Return a new collection will all items that pass the given callback functions truth test.`first()`Get the value of the first item in the collection. If the collection is empty, a `CollectionException` will be thrown.`firstOrDefault($default = null)`Same as above, except instead of throwing an exception, return the provided default value.`get($key)`Get the value associated with the specified key. If the key does not exist, a `CollectionException` will be thrown.`getOrDefault($key, $default = null)`Same as above, except instead of throwing an exception, return the provided default value.`has($key, $value = null)`Checks whether the collection has the specified key, and/or key/value pair.`hasCount($min, $max = null)`Checks whether the collection has the minimum count specified, or a count that falls within the range specified.`isEmpty()`Whether the collection is empty.`keys()`Returns an array of all the keys used by the collection.`last()`Get the value of the last item in the collection. If the collection is empty, a `CollectionException` will be thrown.`lastOrDefault($default = null)`Same as above, except instead of throwing an exception, return the provided default value.`make(array $initial)` *static*Static helper method to instantiate a new collection. Useful for when you want to immediately chain a method. Eg: Collection::make(\[1, 2, 3\])->map(...)`map(Closure $fn)`Execute the callback function provided on each item in the collection. The callback function is passed `$value, $key` as arguments. The return value of the callback function will be saved into a new collection and that collection will be returned as a result`mapWithKey(Closure $fn)`Execute the given callback function for each element in this collection and save the results to a new collection with the specified key. The callback function should return a 1 element associative array, eg: \['key' => 'value'\] to be mapped.`only(array $keys)`Return a new collection containing only the items in the current collection whose keys match the ones provided.`pluck($pluck_key, $deep = true)`Grab and return a new collection will all values that have the specified `key`. By default, this will traverse multidimensional arrays.`push($value)`Return a new collection with the given value pushed onto a copy of the current collection's items.`pushArray(array $data)`Return a new collection with the given array pushed onto a copy of the current collection's items.`pushWithKey($key, $value)`Return a new collection with the given key/value pair pushed onto a copy of the current collection's items.`sort(Closure $fn)`Return a new collection after the user defined sort function has been executed on the items. Same callback function parameters as the PHP `usort` function.`toArray()`Returns the current collection as a standard PHP array.Contributing ============ [](#contributing) Please see `CONTRIBUTING.md` License ======= [](#license) MIT - Copyright (c) 2016 Tristan Strathearn, see `LICENSE` ### Health Score 29 — LowBetter than 57% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity12 Limited adoption so far Community7 Small or concentrated contributor base Maturity64 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
