Laravel Collection put() - PHP

Laravel Collections are an incredibly powerful tool for working with arrays in PHP. They provide a wide range of useful methods for manipulating and transforming data, making it easy to work with complex datasets.

One method available on Laravel Collections is the put() method. In this article, we'll explore how the put() method works and provide some examples of how it can be used in your PHP code.

What is the put() method?

The put() method is used to add a new key-value pair to a Laravel Collection. It takes two arguments: the key to add the value under, and the value to add.

Here's the basic syntax for using the put() method:

$collection->put($key, $value);

Examples

Let's explore some examples of how the put() method can be used in practice.

Example 1: Adding a single key-value pair

In this example, we'll create a new collection and add a single key-value pair using the put() method:

$collection = collect(['name' => 'John']);

$collection->put('age', 30);

// Result: ['name' => 'John', 'age' => 30]

Example 2: Adding multiple key-value pairs

You can also use the put() method to add multiple key-value pairs to a collection at once. You can do this by passing an array of key-value pairs as the second argument to the put() method:

$collection = collect(['name' => 'John']);

$collection->put([
    'age' => 30,
    'email' => 'john@example.com'
]);

// Result: ['name' => 'John', 'age' => 30, 'email' => 'john@example.com']

Example 3: Updating an existing key-value pair

If the key you pass to the put() method already exists in the collection, the value for that key will be updated:

$collection = collect(['name' => 'John', 'age' => 30]);

$collection->put('age', 31);

// Result: ['name' => 'John', 'age' => 31]

Example 4: Adding a key-value pair conditionally

You can use the put() method along with a conditional statement to add a key-value pair only if a certain condition is met:

$collection = collect(['name' => 'John']);

$age = 30;

if ($age > 29) {
    $collection->put('age', $age);
}

// Result: ['name' => 'John', 'age' => 30]

Conclusion

The put() method is a simple yet incredibly useful tool for working with Laravel Collections in PHP. Whether you need to add a single key-value pair or multiple pairs at once, or update an existing value, the put() method makes it easy to manipulate your data in the way you need.
