Eloquent models have two protected arrays, $originaland $changes, which contain the attributes as they were when fetched from storage and the attrbirutes which have been modified, respectively.
Eloquent 模型有两个受保护的数组$original和$changes，它们分别包含从存储中获取时的属性和已修改的属性。
So you can use getOriginal()and getChanges()and compare the differences.
所以，你可以用getOriginal()和getChanges()和比较的差异。
$model = Model::createOrUpdate([...]);
// wasRecentlyCreated is a boolean indicating if the model was inserted during the current request lifecycle.
if (!$model->wasRecentlyCreated) {
$changes = $model->getChanges();
}

This creates an array which will contain the original attribute value and what it was changed to:
这将创建一个包含原始属性值及其更改内容的数组：
if (!$model->wasRecentlyCreated) {
$original = $model->getOriginal();
$changes = [];
foreach ($model->getChanges() as $key => $value) {
$changes[$key] = [
'original' => $original[$key],
'changes' => $value,
];
}
}
e.g.
例如
(
[first_name] => [
[original] => Kevinn
[changes] => Kevin
]
[website] => [
[original] => google.com
[changes] => google.ca
]
)
