Laravel Collection Public API: except

except($keys)

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.

The following example demonstrates the usage of the except method:

 1<?php
 2 
 3// Create a new collection.
 4$collection = collect([
 5    'first_name' => 'John',
 6    'last_name'  => 'Doe',
 7    'password'   => 'some_password'
 8]);
 9 
10// Retrieve all items from the collect
11// except for the password.
12$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:2 [
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<?php
2 
3$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"}"
