Laravel 8 diffKeys() {#collection-method}
2021-07-19 09:34 更新
diffKeys 方法和另外一个集合或 PHP 数组的键（keys）进行比较，然后返回原集合中存在而指定集合中不存在键所对应的键 / 值对：
$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]以上内容是否对您有帮助：
