+The `after` method returns the item after the given item. `null` is returned if the given item is not found or is the last item:

+ $collection = collect([1, 2, 3, 4, 5]);
+
+ $collection->after(3);
+
+ // 4
+
+ $collection->after(5);
+
+ // null
+
+This method searches for the given item using "loose" comparison, meaning a string containing an integer value will be considered equal to an integer of the same value. To use "strict" comparison, you may provide the `strict` argument to the method:
+
+ collect([2, 4, 6, 8])->after('4', strict: true);
+
+ // null
+
+Alternatively, you may provide your own closure to search for the first item that passes a given truth test:
+
+ collect([2, 4, 6, 8])->after(function (int $item, int $key) {
+ return $item > 5;
+ });
