两个日期之间的时差(分钟)

Question

得到这个工作在PHP 5.3

$datetime1 = new DateTime("2011-10-10 10:00:00");
$datetime2 = new DateTime("2011-10-10 10:45:00");
$interval = $datetime1->diff($datetime2);
$hours   = $interval->format('%h'); 
$minutes = $interval->format('%i');
echo 'Diff. in minutes is: '.($hours * 60 + $minutes); 

我怎样才能在php 5.2上运行？有没有可用的等效功能？

搞定了

$date1 = "2011-10-10 10:00:00";
$date2 = "2011-10-10 10:11:00";
echo round((strtotime($date2) - strtotime($date1)) /60);

Answer 1

而不是DateTime你可以使用strtotime和date:

$datetime1 = strtotime("2011-10-10 10:00:00");
$datetime2 = strtotime("2011-10-10 10:45:00");
$interval  = abs($datetime2 - $datetime1);
$minutes   = round($interval / 60);
echo 'Diff. in minutes is: '.$minutes;
