Introduction

Laravel Collections are a powerful feature that allows you to work with arrays of data in a more fluent and expressive way. They provide a wide range of methods to manipulate and filter data efficiently. In this guide, we'll introduce you to some common methods used in Laravel Collections.

Prerequisites

Before we get started, ensure you have the following:

• An existing Laravel project
• Basic knowledge of PHP

Creating a Collection

In Laravel, you can create a collection from an array using the `collect` helper function:

            
$collection = collect([1, 2, 3, 4, 5]);
            
        

Common Collection Methods

Laravel Collections provide a wide range of methods for working with data. Here are some common methods:

1. `map`

The `map` method applies a callback to each item in the collection and returns a new collection with the modified values.

            
$modifiedCollection = $collection->map(function ($item) {
    return $item * 2;
});
            
        

2. `filter`

The `filter` method filters the collection based on a callback and returns a new collection with only the items that pass the filter.

            
$filteredCollection = $collection->filter(function ($item) {
    return $item % 2 == 0;
});
            
        

Chaining Methods

One of the strengths of Laravel Collections is the ability to chain methods together, making complex operations more readable and efficient.

            
$modifiedAndFiltered = $collection->map(function ($item) {
    return $item * 2;
})->filter(function ($item) {
    return $item % 4 == 0;
});
            
        

Conclusion

Laravel Collections offer a powerful and expressive way to work with data. By mastering the common methods and learning to chain them effectively, you can simplify data manipulation in your Laravel applications.
