How to add new value in collection laravel?

Question

I have the following loop where I try to add a new value:

 foreach ($pro->sig()->get() as $key => $sig) {             $sig->val = 2;         } 

When I print the output of $pro->sig() I don't have the new value $sig->val

If you have a collection you can use push or put method.

Example with put:

$collection = collect(['product_id' => 1, 'name' => 'Desk']);  $collection->put('test', 'test');  $collection->all(); 

The output will be:

['product_id' => 1, 'name' => 'Desk', 'test' => 'test'] 

Example with push:

$collection = collect([1, 2, 3, 4]);  $collection->push(5);  $collection->all(); 

Output:

[1, 2, 3, 4, 5]

Answer 2

In my example, I tried like the below

foreach ($user->emails as $key => $email) {    $email->test = "test"; } return $user->emails; 

It outputs like,

  {     "id": 76,     "user_id": 5,     "additional_email": "[email protected]",     "test": "test"   } 

Please try like this.
