提问by myckhel
public function recover(Request $request){
$email = $request->input('email');
// Create tokens
$selector = bin2hex(random_bytes(8));
$token = random_bytes(32);
$url = sprintf('%s', route('recover.reset',['selector'=>$selector, 'validator'=>bin2hex($token)]));
// Token expiration
$expires = new DateTime('NOW');
$expires->add(new DateInterval('PT01H')); // 1 hour
// Delete any existing tokens for this user
DB::delete('delete * from password_reset where email =?', $email);
// Insert reset token into database
$insert = $this->db->insert('password_reset',
array(
'email' => $email,
'selector' => $selector,
'token' => hash('sha256', $token),
'expires' => $expires->format('U'),

Above your class definition, import the class with a use statement.
在类定义上方，使用 use 语句导入类。
use DateTime;
The alternative to that is to use the fully qualified namespace in your code. With PHP classes in the global namespace, all this means is a single backslash before the class name:
另一种方法是在代码中使用完全限定的命名空间。对于全局命名空间中的 PHP 类，所有这一切都意味着类名前有一个反斜杠：
$expires = new \DateTime('NOW');
I prefer the first approach, as it allows you to see every class used in that file at a glance.
我更喜欢第一种方法，因为它使您可以一目了然地看到该文件中使用的每个类。

DateTime is a PHP Object, so you can declare it using the slash before:
DateTime 是一个 PHP 对象，因此您可以在前面使用斜杠声明它：
new \DateTime();
Or declaring it before you use and instantiating later:
或者在使用之前声明并稍后实例化：
use DateTime;
class Etc
{
public function test()
{
$datetime = new DateTime();
}
}
回答by Bilal Ahmed
Add a backslash \(to define root namespace)
添加反斜杠\（定义root namespace）
$dateTime = new \DateTime();
also you can use classes
你也可以使用类
use DateTime;
use DatePeriod;
use DateInterval;
