$originalFoo = $model->getOriginal('foo');
$originalFoo = $model->getOriginal('foo');

If you want to use mutatorin the majority of the code but sometimes would like to access the original value, you can do it by fetching all attributes using getAttributes()method of your model and then fetching the value from there, e.g.:
如果您想在大部分代码中使用mutator但有时想要访问原始值，您可以通过使用模型的getAttributes()方法获取所有属性然后从那里获取值来实现，例如：
$originalFoo = $model->getAttributes()['foo'];

If you want the raw field straight out of database skipping the mutator then
如果您希望直接从数据库中获取原始字段跳过 mutator，那么
$mode->getRawOriginal('attribute')
is the way to go. $model->getOriginal()will give you the mutator value notthe raw data you want.
是要走的路。$model->getOriginal()会给你 mutator 值而不是你想要的原始数据。

Laravel 7 and Symfony 5 respectively
Laravel 7 和 Symfony 5 分别
$model->getRawOriginal()
The getOriginal Method
Likelihood Of Impact: Low
The
$model->getOriginal()method will now respect any casts and mutators defined on the model. Previously, this method returned the uncast, raw attributes. If you would like to continue retrieving the raw, uncast values, you may use thegetRawOriginalmethod instead.
getOriginal 方法
影响可能性：低
该
$model->getOriginal()方法现在将尊重模型上定义的任何强制转换和修改器。以前，此方法返回未转换的原始属性。如果您想继续检索原始的、未转换的值，您可以改用该getRawOriginal方法。

Something that might be worth mentioning as well is that the Laravel model class overwrites the magic methods for __setand __get, so you can also retrieve the originalattribute dynamically i.e. $model->original.
值得一提的是，Laravel 模型类覆盖了__setand的魔法方法__get，因此您还可以original动态检索属性，即$model->original。
