has($key)
The has method is used to determine if a item exists in the collection based on a given $key. The has method returns true if the item exists and false if it does not.
The following example demonstrates the usage of the has method:
1<?php
2
3use Illuminate\Support\Collection;
4
5// Create a new collection instance.
6$collection = new Collection([
7 'first' => 'I am first',
8 'second' => 'I am second'
9]);
10
11// true
12$collection->has('first');
13
14// true
15$collection->has('second');
16
17// false
18$collection->has('third');
