Laravel 5 Collections: Excluding Collection Elements With except

The except method will return all the key/value pairs in the collection where the keys in the collection are not in the supplied $keys array. Internally, this method makes a call to the Illuminate\\Support\\Arr:except($array, $keys) helper function.

#Signature

1public function except(
2    $keys
3);

#Example Use

The following example demonstrates the usage of the except method:

 1// Create a new collection.
 2$collection = collect([
 3    'first_name' => 'John',
 4    'last_name'  => 'Doe',
 5    'password'   => 'some_password'
 6]);
 7
 8// Retrieve all items from the collect
 9// except for the password.
10$data = $collection->except(['password']);

After the above code has executed, the $data variable would contain a value similar to the following output:

1Collection {
2  #items: array [
3    "first_name" => "John"
4    "last_name"  => "Doe"
5  ]
6}

We can also combine the except method with the toJson method to easily remove sensitive data from information before sending it to an end user:

1$jsonData = $collection->except(['password'])->toJson();

After the above code has executed, the $jsonData variable would hold a value similar to the following JSON string:

1"{"first_name":"John","last_name":"Doe"}"
