What is the use of the contains() method in Laravel collections?

The contains() method in Laravel collections is used to check if a collection contains a specific value. It returns true if the collection contains the value and false otherwise. This method can be useful when you need to quickly check if a certain value exists in a collection before performing further operations on it.


What is the purpose of the pluck() method in Laravel collections?

How to retrieve a specific range of values from a Laravel collection?

To retrieve a specific range of values from a Laravel collection, you can use the splice method. Here's an example of how you can retrieve values starting from index 2 and containing 4 items from a collection:

1
2
3
4
5
$collection = collect([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);

$range = $collection->splice(2, 4);

// $range will contain [3, 4, 5, 6]


In the example above, splice(2, 4) retrieves values starting from index 2 (3rd element) and gets 4 items from the collection. You can adjust the starting index and number of items to retrieve the desired range of values.

    echo "Collection is empty";
} else {
    // Collection is not empty
    echo "Collection is not empty";
}


The isEmpty() method returns true if the collection is empty and false if it is not empty.
