The count
method will return the number of elements contained within the collection's inner array; it is synonymous with PHP's count
function.
#Signature
1public function count();
#Example Use
The count
method is a straightforward method and simply returns the total number of items in the collection. The count
method returns an integer.
1use Illuminate\Support\Collection;
2
3// Create a new collection instance.
4$collection = new Collection([
5 'first', 'second', 'third'
6]);
7
8// 3
9$collection->count();
It should also be noted that this method exists to implement PHP's Countable
interface. This means that PHP's count
function can be invoked on a collection instance:
1// Create a new collection instance.
2$collection = collect([
3 'first', 'second', 'third'
4]);
5
6// 3
7$count = count($collection);
