Explain how to use the `contains` method in Laravel collections.
Answer: In Laravel, the `contains` method is used to determine if a collection contains a given item. You can use it in several ways:
1. By value: Checks if a specific value exists in the collection.
“`php
$collection = collect([1, 2, 3, 4]);
$contains = $collection->contains(2); // Returns true
“`
2. By key-value pair: Checks if a collection of key-value pairs contains a specified key-value combination.
“`php
$collection = collect([‘name’ => ‘John’, ‘age’ => 25]);
$contains = $collection->contains(‘name’, ‘John’); // Returns true
“`
3. Using a callback: Pass a callback function to determine if any item meets a specified condition.
“`php
$collection = collect([1, 2, 3, 4]);
$contains = $collection->contains(function ($value) {
return $value > 2; // Returns true
});
“`
Use `contains` when you need to check for item existence efficiently within a Laravel collection.
