The keys
method is used to retrieve all of keys stored inside the MessageBag
instance.
#Signature
The signature of the keys
method is:
1public function keys();
#Example Use
The following code example demonstrate the usage of the keys
method:
1use Illuminate\Support\MessageBag;
2
3// Create a new MessageBag instance.
4$messageBag = new MessageBag;
5
6// Add items to the MessageBag
7$messageBag->add('first', 'First Message');
8$messageBag->add('second', 'Second Message');
9$messageBag->add('third', 'Third Message');
10$messageBag->add('fourth', 'Fourth Message');
11
12// Get the MessageBag keys.
13$keys = $messageBag->keys();
After the above code has executed, the $keys
variable will be an array that contains a value similar to the following output:
1array
2 0 => string 'first'
3 1 => string 'second'
4 2 => string 'third'
5 3 => string 'fourth'
It can be seen that the results contain only the keys that were added to the MessageBag
instance.
