Collections sune mai karfi, fluent wrapper a kusa da arrays, wanda ya ba da dozin abubuwan da ake iya sadawa don aiki da data cikin kyau (map, filter, reduce, groupBy, da dai sauransu). Sakamakon buhatun Eloquent ana dawawe su azaman Collections, saboda kake amfani da su jiya-jiya.
$collection = collect([1, 2, 3, 4, 5]);
$result = $collection
->filter(fn($n) => $n % 2 === 0) // [2, 4]
->map(fn($n) => $n * 10) // [20, 40]
->values(); // re-index
$collection->sum(); // 15
$collection->avg(); // 3
$collection->max(); // 5
A Collection suna sanye da array kuma suna ba da fluent, chainable API — fiye da aiki da nanu array functions, kuma yana iya sadawa don tsabar data pipelines.
$users = User::all(); // returns a Collection of User models
$users->where('active', true) // filter
->sortBy('name')
->map(fn($u) => $u->name)
->take(10);
$users->pluck('email'); // extract one field → a collection of emails
$users->groupBy('role'); // group by a field → role => [users]
$users->keyBy('id'); // index by id
Domin Eloquent yayi dawawe Collections, zaka iya canzawa da kyau sakamakon buhatun a cikin PHP — duk da haka, don manyan datasets, fi karfa buhatun database a gida kawai, ba tilo kome kuma fil a PHP.
map, filter, reduce, each transform/iterate
pluck, keyBy, groupBy, partition restructure
sum, avg, min, max, count aggregate
sort, sortBy, reverse, unique order/dedup
first, last, take, skip, chunk slice
contains, every, some, where query
implode, flatten, collapse, merge combine
Collections sune muhimmiyar, yada cikin Laravel feature — suna sanya aiki da arrays da data jamil kuma yana iya faadi, kuma tun Eloquent query results su ne Collections, kake amfani da su jiya-jiya lokacin kulle da data na data, wanda yake sanya su aiki-aiki, muhimmiyar ilimi.
Mahakin asali shine fluent, chainable API: maimakon magudimakuyar, imperative array manipulation, Collections ba ka damar bayyana canza data (filtering, mapping, grouping, aggregating, sorting) azaman karantawa, haɗa method chains — babbar halin aiki kuma ingan likita wanda ya nuna elegant style na Laravel.
Jihar rich method set (map/filter/reduce don canza, pluck/groupBy/keyBy don sake tsarawa, aggregation da sorting methods) ya ba ka damar aiki da data tsabta kuma shi ne dole don aiki jiya-jiya da Eloquent results (wanda yayi dawawe Collections wanda za ka canza sai).
Jihar Collections — su fluent API, jituwa na methods da suke akwai, da cewa Eloquent suna amfani da su — shi ne tushe don aiki mai yawa na Laravel, tun da canza data shi yau da kullum kuma Collections shine ta yaya Laravel ta sanya shi jamil. (Babbar mahimmi na aiki: don fil/tsara manyan datasets, fi karfa aiki a cikin database query maimakon tilo duka rikodin cikin Collection kuma aiki a PHP — Collections ne don data manipulations a cikin ajiya, ba maimaiko don buhatun da kyau.) Jiyattar Collections shine alama na idiomatic, aiki mai yawa na Laravel code.
