date_diff（）期望参数1为DateTimeInterface，给定字符串 [英] date_diff() expects parameter 1 to be DateTimeInterface, string given

问题描述

我遇到了这个问题，我不知道该怎么办...
它们具有相同的格式

i got this problem and i don't know what to do... they have thesame format

$date_expire = '2014-08-06 00:00:00';
$date1 = date("Y-m-d G:i:s");
$date2 = date_create($date_expire);

$diff = date_diff($date1, $date2); //this line makes error..

推荐答案

因为传递字符串，而 date_diff 期望 datetime 对象，

Because you are passing string whereas date_diff expects datetime object,

$date_expire = '2014-08-06 00:00:00';    
$date = new DateTime($date_expire);
$now = new DateTime();

echo $date->diff($now)->format("%d days, %h hours and %i minuts");

演示 。
