In the above example, we create a new `User` object and set its attributes using the `attributes` property. We then call the `unsetAttributes` method and pass it an array of attributes that we want to remove from the object. Example 2: Using `unsetAttributes` in Symfonyphp use Symfony\Component\HttpFoundation\Request; $request = Request::createFromGlobals(); $request->attributes->set('name', 'John Doe'); $request->attributes->set('email', 'john.doe@example.com'); $request->attributes->set('age', 30); $request->attributes->unset('email'); ``` In this example, we create a new `Request` object and set some attributes using the `setAttribute` method. We then call the `unset` method on the `attributes` property and pass it the name of the attribute we want to remove. Based on these examples, it can be inferred that the `unsetAttributes` method is commonly used in PHP packages and libraries for manipulating objects' attributes.
