php - 如何获得 Twig 的天数差异

Question

• 如何获取与当天相差的天数。

• tweetedAt:“2015-02-22 09:56:42”。

Twig

{% for key,value in data.about %}
{% set tweets_date=(value.tweetedAt|date).date("now").format('%a') %}
{% endfor %}

我也试过

{% set dd='now'|date('d-m-Y') %}
{% set tweets_date=(value.tweetedAt|date).dd.format('%a') %}

最后我试过了，但它给出了错误:

A hash key must be a quoted string, a number, a name, or an expression enclosed in parentheses (unexpected token "punctuation" of value "{"

{% set difference = {{ date("m/d/Y") }}.diff(date(value.tweetedAt)) %}
{% set leftDays = difference.days %}

错误:

<span class="small light_grey">{{tweets_date}}</span>

Impossible to invoke a method ("date") on a string variable ("June 6, 2015 01:06") in AcmeBundle

• 如何从 tweet_date 中获取几天前的差异。

更新了我的项目，通过 composer 安装 twig/extensions

user@intermsh-OptiPlex-380:~$ composer require twig/extensions

我试过这段代码，它有效。

{% set difference = date(value.tweetedAt|date('Y/m/d')).diff(date('now'|date('Y/m/d'))) %}
{% set leftDays = difference.days %}
