Laravel - Collections - Method Diffkeys
The diffKeys
method compares the collection against another collection or a plain PHP array
based on its keys. This method will return the key / value pairs in the original collection that are not present in the given collection:
$collection = collect([
'one' => 10,
'two' => 20,
'three' => 30,
'four' => 40,
'five' => 50,
]);
$diff = $collection->diffKeys([
'two' => 2,
'four' => 4,
'six' => 6,
'eight' => 8,
]);
$diff->all();
// ['one' => 10, 'three' => 30, 'five' => 50]
