使用以下代码，

protected $token;
 /** @Column(name="assigneddate", type="datetime", columnDefinition="datetime") */
private $assigneddate;


/** @Column(name="expirydate", type="datetime", columnDefinition="datetime") */
private $expirydate;

/** @PreUpdate */
public function updated()
{
    //$this->assigneddate = new \DateTime("now");
}
public function __construct()
{

    $this->expirydate = $this->expirydate = new \DateTime("now");
    $this->assigneddate = $this->assigneddate = new \DateTime("now");

}

如何添加2小时到这个？

How do I add 2 hours to this?

推荐答案

这更多是一个PHP问题。要添加时间到 DateTime PHP对象，您可以使用添加方法，该方法接受 DateInterval 对象。在您的情况下，如果要在到期日期添加2个小时：

This is more of a PHP question. To add time to a DateTime PHP object, you use the add method, which accepts a DateInterval object. In your case, if you want to add 2 hours to the expiry date:

// Create DateTime object with current time/date
$this->expirydate = new \DateTime("now");
// Add two hours
$this->expirydate->add(new \DateInterval("PT2H"));

其中PT2H表示周期时间2小时，如此处。

Where "PT2H" means a "period time of 2 hours", as specified here.
