Symfony2 DateTime差异不行 [英] Symfony2 DateTime difference not working

问题描述

我的树枝上有这个var：

I have this var in my twig templete:

{{aWorker.timeToRetirement|date('Y-m-d')}}

当我执行页面时，它正好返回这个文本：'Ym-d'without''当然。现在我真正想要得到的是两个日期之间的区别，让我们说一个未来的日期（一个人/工作者的退休日期，你可以得到更多的信息，如果你需要，我在做什么 here ） '2060-12-01'和今天的日期'2013-10-03'。我想在我的实体类中使用这个var和方法：

when I execute the page it's returning exactly this text: 'Y-m-d' without '' of course. Now what I really want to get is the difference between 2 dates, lets say a future date (is the retirement date of a person/worker you can get more info about what I'm doing if u need it here) '2060-12-01' and today's date '2013-10-03'. I want to do that using this var and method in my Entity class:

//...
//Var containing the retirement date
private $retireYear;
//var to store time to retirement from today
private $timeToRetirement;
//...
    public function getTimeToRetirement (){
        $this->timeToRetirement = $this->retireYear->diff(new \DateTime('today'));
    return $this->timeToRetirement;
}

我做错了什么？这是var没有返回今天和退休日期之间的差异

What am I doing wrong? whay is the var not returning the difference between today and the retirement date

推荐答案

你的函数返回一个 DateInterval 对象，所以你需要使用它的 format（）方法来生成所需的字符串。

Your function is returning a DateInterval object, so you need to use its format() method to generate your required string.
