PHP는 두 타임스탬프 사이의 시간 간격을 계산합니다.

//输入两个时间戳，计算差值，也就是相差的小时数，如返回2:10，则表示输入的两个时间相差2小时10分钟 
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; 
}

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(&#39;content&#39;).innerHTML = &#39;两个日期相差 <strong style="color:red">&#39;+time+&#39;</strong> 天！&#39;;}</script>
