注意：类DateTime的对象无法转换为int Symfony2

Question

我希望在创建操作期间获得并节省两次总时数

YAML

    timein:
        type: time
    timeout:
        type: time
        nullable: true
    total:
        type: time
        nullable: true

实体

 private $timein;//DateTime
 private $timeout;//DateTime
 private $total;//DateTime

 /**
 * Get total
 *
 * @return \DateTime
 */
public function getTotal()
{
    return $this->total;
}

/**
 * Set total
 *
 * @param \DateTime $total
 *
 * @return Timerecord
 */
public function setTotal($total)
{
    $this->total = $total;

    return $this;
}

public function getWorkedHoursTimeinTimeout()
{


  if (!empty($this->timein) && !empty($this->timeout)) {
        //if already timed in and timed out, calculate hours from timein to timeout
        $start = $this->timein;
        $end = $this->timeout;
        $start1 = $start;
        $end1 = $end;
        $total_hours = round(($end1-$start1) / 3600);//option1 

    return  $total_hours;



    } /*else {
        $this->total = "";
    }*/

}

现在在控制器内部，我想像这样保存timeim和timeout的总小时数

 $entity->setTotal($entity->getWorkedHoursTimeinTimeout());
        $em->persist($entity);
        $em->flush();

但是我收到了这个错误

  

注意：类DateTime的对象无法转换为int

$ timein，$ total和$ timeout实际上是Doctrine.yml中的时间类型，但它会在运行时自动转换为DateTime

  php app/console doctrine:generate:entities

在Mysql中，$ timein和$ timeout是时间类型

现在我重构了我的getWorkedHoursTimeinTimeout（）

public function getWorkedHoursTimeinTimeout()
{


  if (!empty($this->timein) && !empty($this->timeout)) {
        //if already timed in and timed out, calculate hours from timein to timeout
        $start = $this->timein;
        $end = $this->timeout;
        $start1 = $start;
        $end1 = $end;
        $total_hours = $end1->diff($start1);//option1 

    return  $total_hours;

}

这不返回任何错误，但不保存实际的总小时数，而是保存值

 00:00:00

现在我尝试返回并保存$ timein或$ timeout

的值

 if (!empty($this->timein) && !empty($this->timeout)) {
        //if already timed in and timed out, calculate hours from timein to timeout
        $start = $this->timein;
        $end = $this->timeout;
        $start1 = $start;
        $end1 = $end;
        $total_hours = $end1->diff($start1);//option1 

    return  $start;//02:00:04



    } /*else {

它实际上保存到Mysql中的总列

有关于此的任何想法吗？
