Laravel contains() Method

contains() method checks whether Laravel Collections contains certain given value or not. If you pass one value to the contains() method, it will check whether collection has any value matching to the parameter.

$users = collect(['name' => 'John Doe', 'email' => 'johndoe@example.com']);

$users->contains('John Doe');

// true

$users->contains('John Admin');

// false

$collection = collect([
			['id' => '200', 'amount' => '500'],
			['name' => '201', 'country' => '200'],
		]);

$collection->contains('amount', '500');
