PHP function to calculate the time between two timestamps in hours

This is a php code that can be specific to the hour

Copy the code The code is as follows:

/* Author: Yang Yu yangyu@sina.cn */
//Enter two timestamps and calculate the difference, also It is the number of hours difference. If 2:10 is returned, it means that the difference between the two input times is 2 hours and 10 minutes.
function hours_min($start_time,$end_time){
if (strtotime($start_time) > strtotime($end_time) ) list($start_time, $end_time) = array($end_time, $start_time);
$sec = $start_time - $end_time;
$sec = round($sec/60);
$min = str_pad($sec% 60, 2, 0, STR_PAD_LEFT);
$hours_min = floor($sec/60);
$min != 0 && $hours_min .= ':'.$min;
return $hours_min;
}

Copy the code The code is as follows:

function get_date_different(){
var _date_1 = document.getElementById('date1').value.replace(/(^s* )|(s*$)/g,'');
var _date_2 = document.getElementById('date2').value.replace(/(^s*)|(s*$)/g,'');
_date_1 = new Date(_date_1);
_date_2 = new Date(_date_2);
var days= _date_2.getTime() - _date_1.getTime();
var time = parseInt(days / (1000 * 60 * 60 * 24 ));
document.getElementById('content').innerHTML = 'The difference between the two dates is'+time+' days! ';}

The above introduces the PHP function to calculate the time between two timestamps, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
