PHP datetime diff错误

我想在PHP中的两个DateTime对象之间得到一个区别，答案似乎是错误的。正如你所看到的，diff（）函数给出了4小时41分钟的时间差，但时间差显然更接近7小时。PHP datetime diff错误

$eastern_tz = new DateTimeZone("US/Eastern"); 

$now   = new DateTime("now", $eastern_tz); 
$future_date = new DateTime($future_date_string); //'2011-05-11 12:00:00' 

$future_date->setTimezone($eastern_tz); 

$interval = $future_date->diff($now); 

var_dump($now); 
var_dump($future_date); 
var_dump($interval); 

return $interval->format($format); //"%d days, %h hours, %i minutes, %s seconds"

//调试信息

object(DateTime)[483] 
    public 'date' => string '2016-06-15 09:18:41' (length=19)

好吧，您的DEBUG信息显示$ future_date值不是您声称要插入的值。你确定你在$ future_date_string中提供的值是正确的吗？ – Tularis

根据调试信息中显示的值，答案是正确的！ –

当您创建$future_date = new DateTime($future_date_string);，这是PHP的默认时区？

$future_date->setTimezone($eastern_tz);只有在呈现日期或导入新字符串时才需要。解析$future_date_string为时已晚。

使用我的代码，它会为你工作。

$fromTimes = date('d-m-Y',strtotime('15-06-2016 06:57:27')); //from date and time 
$toTimess = date('d-m-Y',strtotime('17-06-2016 10:25:30')); //to date and time 
$date_a = new DateTime($toTimess); //converting the date and time 
$date_b = new DateTime($fromTimes); 
$interval = date_diff($date_a,$date_b); //find difference 
$day = $interval->format('%d')*24; //get day difference 
$hours = $interval->format('%h'); // get hour 
$mins = $interval->format('%i'); //get mins 
if($mins <10) 
{ $mins = '0'.$mins; } 
echo $total_hours = ($hours + $day).':'.$mins;

希望它会为你工作...
