What is Laravel Collection?
Laravel's Illuminate\Support\Collection class provides a fluent, convenient wrapper for working with arrays of data. It offers a wide variety of methods for manipulating and transforming data, similar to JavaScript's array methods or functional programming utilities.
Collections are immutable — each operation returns a new Collection instance rather than modifying the original. This makes them predictable and easy to reason about.
How to Use
- Enter your data — Paste a JSON array in the input area. Each object should have the same structure with consistent keys.
- Choose an operation — Select from map(), filter(), pluck(), sortBy(), groupBy(), unique(), or chunk().
- Configure parameters — Depending on the operation, you may need to specify field names, values, or sizes.
- Run and inspect — Click "Run Operation" to see the result and the equivalent Laravel PHP code.
id="frequently-asked-questions" Frequently Asked Questions
What is the difference between map() and pluck()?
map() transforms every item in the collection and returns the same number of items, letting you rewrite each value or object. pluck() extracts a single field (key) from every item and returns a plain array of just those values — for example, collecting all the "name" values from a list of user objects.
Do collection methods modify the original data?
No. Laravel Collections are immutable — every operation returns a new Collection instance and leaves the original untouched. This makes them predictable and safe to chain. Some methods like filter() also re-index the array; use values() if you want to reset the keys afterwards.
Why does filter() keep its original keys?
filter() preserves the original numeric keys of the items that pass the condition, which can leave gaps in the sequence. If you need a consecutive index, chain ->values() after filter() to re-number the result from zero.
Is my data sent to a server?
No. Every operation runs entirely in your browser. Your JSON data is never sent to any server.
