The PHP documentation is an excellent resource to learn more about the built-in ArrayObject class (introduced in PHP 5), which allows objects to work as arrays. put undot The callback should return an associative array containing a single key / value pair: The max method returns the maximum value of a given key: The median method returns the median value of a given key: The merge method merges the given array or collection with the original collection. dump mapInto count Connect and share knowledge within a single location that is structured and easy to search. load The count method returns the total number of items in the collection: The countBy method counts the occurrences of values in the collection. The map method iterates through the collection and passes each value to the given callback. (Ep. setVisible The replace method behaves similarly to merge; however, in addition to overwriting matching items that have string keys, the replace method will also overwrite items in the collection that have matching numeric keys: This method works like replace, but it will recur into arrays and apply the same replacement process to the inner values: The reverse method reverses the order of the collection's items, preserving the original keys: The search method searches the collection for the given value and returns its key if found. The each method iterates over the items in the collection and passes each item to a closure: If you would like to stop iterating through the items, you may return false from your closure: The eachSpread method iterates over the collection's items, passing each nested item value into the given callback: You may stop iterating through the items by returning false from the callback: The every method may be used to verify that all elements of a collection pass a given truth test: If the collection is empty, the every method will return true: The except method returns all items in the collection except for those with the specified keys: For the inverse of except, see the only method. takeWhile isNotEmpty Would it be possible for a civilization to create machines before wheels? The Eloquent collection object extends Laravel's base collection, so it naturally inherits dozens of methods used to fluently work with the underlying array of Eloquent models. Since collect() is part of the Enumerable contract, you can safely use it to get a Collection instance. We believe development must be an enjoyable and creative experience to be truly fulfilling. min The append method may be used to indicate that an attribute should be appended for every model in the collection. In this scenario, the firstWhere method will return the first item where the given item key's value is "truthy": The flatMap method iterates through the collection and passes each value to the given closure. ['name' => 'Taylor Otwell', 'age' => 36]. Now I would like to convert this to a collection so I sort by the keys website or url. 'PROD-100' => ['product_id' => 'prod-100', 'name' => 'Desk'].

Asking for help, clarification, or responding to other answers. Likewise, if a map operation returns a collection that does not contain any Eloquent models, it will be converted to a base collection instance. ['name' => 'Desk', 'colors' => ['Black', 'Mahogany']]. The macro closure may access the collection's other methods via $this, just as if it were a real method of the collection class. whereStrict contains Methods that mutate the collection (such as shift, pop, prepend etc.) This method is similar to the reduce method; however, it can accept multiple initial values: The reject method filters the collection using the given closure. Can Visa, Mastercard credit/debit cards be used to receive online payments? zip. The sorted collection keeps the original array keys, so in the following example we will use the values method to reset the keys to consecutively numbered indexes: If your sorting needs are more advanced, you may pass a callback to sort with your own algorithm. countBy So, creating a collection is as simple as: Note isEmpty If you need to sort a collection of nested arrays or objects, see the sortBy and sortByDesc methods. * Create a new ResourceCollection instance. whereIn * Create a new Eloquent Collection instance. firstWhere If the collection's values are Eloquent models, the models will also be converted to arrays. Instead, you should use the sort method and invert your comparison. Laravel is a PHP web application framework with expressive, elegant syntax. pipeThrough In addition to the methods defined in the Enumerable contract, the LazyCollection class contains the following methods: The takeUntilTimeout method returns a new lazy collection that will enumerate values until the specified time.

Such an approach makes the following possible: I'd recommend checking out Pull Request #36245 for details on the implementation. sortBy chunk join mergeRecursive firstWhere The toArray method converts the collection into a plain PHP array. reduce Is it legal to intentionally wait before filing a copyright lawsuit to maximize profits? keys For more information, refer to the PHP documentation on uksort, which is the PHP function that sortKeysUsing method utilizes internally. Any models of the same type with the same primary key as another model in the collection are removed: If you would like to use a custom Collection object when interacting with a given model, you may define a newCollection method on your model: Once you have defined a newCollection method, you will receive an instance of your custom collection anytime Eloquent would normally return an Illuminate\Database\Eloquent\Collection instance. 'prod-100' => ['product_id' => 'prod-100', 'name' => 'Desk']. toArray isEmpty After that time, the collection will then stop enumerating: To illustrate the usage of this method, imagine an application that submits invoices from the database using a cursor. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. makeHidden The duplicates method retrieves and returns duplicate values from the collection: If the collection contains arrays or objects, you can pass the key of the attributes that you wish to check for duplicate values: This method has the same signature as the duplicates method; however, all values are compared using "strict" comparisons. To pad to the left, you should specify a negative size. partition ['name' => 'SALLY', 'school' => 'ARKANSAS', 'age' => '28']; ['name' => 'iPhone 6S', 'brand' => 'Apple']. 8 Answers Answer by Ariel Nielsen The toArray method converts the collection into a plain PHP array. The closure is free to modify the item and return it, thus forming a new collection of modified items. For instance, let's use the each higher order message to call a method on each object within a collection: Likewise, we can use the sum higher order message to gather the total number of "votes" for a collection of users: Warning By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. The closure should return true if the item should be removed from the resulting collection: For the inverse of the reject method, see the filter method. ['name' => 'Jim', 'deleted_at' => '2019-01-01 00:00:00']. What is the Modified Apollo option for a potential LEO transport? make forget First returned collection from type Illuminate\Database\Eloquent\Collection. skipUntil In general, collections are immutable, meaning every Collection method returns an entirely new Collection instance. You could define a scheduled task that runs every 15 minutes and only processes invoices for a maximum of 14 minutes: While the each method calls the given callback for each item in the collection right away, the tapEach method only calls the given callback as the items are being pulled out of the list one by one: The remember method returns a new lazy collection that will remember any values that have already been enumerated and will not retrieve them again on subsequent collection enumerations: Laravel is a web application framework with expressive, elegant syntax. 1 => ['product' => 'Desk', 'price' => 200]. reduceSpread 587), The Overflow #185: The hardest part of software is requirements, Starting the Prompt Design Site: A New Home in our Stack Exchange Neighborhood, Testing native, sponsored banner ads on Stack Overflow (starting July 6), Temporary policy: Generative AI (e.g. flatMap Laravel is a Trademark of Taylor Otwell.

Each sort operation should be an array consisting of the attribute that you wish to sort by and the direction of the desired sort: When sorting a collection by multiple attributes, you may also provide closures that define each sort operation: This method has the same signature as the sortBy method, but will sort the collection in the opposite order. unwrap This method behaves like the array_pad PHP function. Both of these classes implement the Illuminate\Support\Enumerable contract, which defines the following methods: all skip If necessary, you may define macros that accept additional arguments: For the majority of the remaining collection documentation, we'll discuss each method available on the Collection class. In some cases, however, you need the Eloquent Database Collection, then you take the second one. The resulting collection will preserve the original collection's keys: The intersectAssoc method compares the original collection against another collection or array, returning the key / value pairs that are present in all of the given collections: The intersectByKeys method removes any keys and their corresponding values from the original collection that are not present in the given array or collection: The isEmpty method returns true if the collection is empty; otherwise, false is returned: The isNotEmpty method returns true if the collection is not empty; otherwise, false is returned: The join method joins the collection's values with a string. Short answer extended: There are different collections. sliding whereInstanceOf Optionally, you may pass a comparison operator as the second parameter. The returned collection keeps the original array keys, so in the following example we will use the values method to reset the keys to consecutively numbered indexes: When dealing with nested arrays or objects, you may specify the key used to determine uniqueness: Finally, you may also pass your own closure to the unique method to specify which value should determine an item's uniqueness: The unique method uses "loose" comparisons when checking item values, meaning a string with an integer value will be considered equal to an integer of the same value. The whereInstanceOf method filters the collection by a given class type: The whereNotBetween method filters the collection by determining if a specified item value is outside of a given range: The whereNotIn method removes elements from the collection that have a specified item value that is contained within the given array: The whereNotIn method uses "loose" comparisons when checking item values, meaning a string with an integer value will be considered equal to an integer of the same value. The pull request description has excellent details to get you up to speed with what these casts bring to Laravel 8: Of course, Laravel already includes an ability to cast a JSON / TEXT column that contains JSON to an array or collection like so: However, this does have some downsides. For the inverse of contains, see the doesntContain method. ['name' => 'Taylor Otwell', 'age' => 34]. mapWithKeys rev2023.7.7.43526.

If you wish to create a new collection instead, use the map method. If the item is not found, false is returned: The search is done using a "loose" comparison, meaning a string with an integer value will be considered equal to an integer of the same value. That means it does not behave like a typical array (- it will be array-like, but don't treat it like it is one -) until you call all() or toArray() on it. except Not the answer you're looking for?

Each higher order message can be accessed as a dynamic property on a collection instance. The forPage method returns a new collection containing the items that would be present on a given page number. The unless method will execute the given callback unless the first argument given to the method evaluates to true: A second callback may be passed to the unless method. flatten concat Furthermore, almost every method returns a new Collection instance, allowing you to preserve the original copy of the collection when necessary: all The sorted collection keeps the original array keys, so in the following example we will use the values method to reset the keys to consecutively numbered indexes: The sortBy method accepts sort flags as its second argument: Alternatively, you may pass your own closure to determine how to sort the collection's values: If you would like to sort your collection by multiple attributes, you may pass an array of sort operations to the sortBy method.
