2次之间的差异在小时数字段中显示12

Question

$start_time = '10:36:23';  
$end_time = '10:36:26';   

$v =  strtotime($end_time) - strtotime($start_time);  


echo date("h:i:s", $v);

Result should be 00:00:03. But is showing 12:00:03.

How can i resolve this?

Answer 1

Lowercase h gives you the hour in 12-hour format. So an hour of zero is after midnight which is 12 AM. If you use uppercase H it will display as you want.

echo date("H:i:s", $v);

Your difference is not actually a time, it is a time span.
