我正在准备用 php 进行数学运算我有 2 个变量,
$a2 = $info["Hora_final"]; //END TIME Example-> 15:30:00
$a1 = $info["Hora_inicial"];//FIRST TIME Example-> 10:00:20
But i want this operation (-) minus.
$res = $a2 - $a1 ;
echo $res;
//output 5,30 Hours difference for example.
我尝试使用此功能,但与我想要的不同。
$a2 = $info["Hora_final"];
$a1 = $info["Hora_inicial"];
$h2h = date('H', strtotime($a2));
$h2m = date('i', strtotime($a2));
$h2s = date('s', strtotime($a2));
$hora2 =$h2h." hour ". $h2m ." min ".$h2s ." second";
$horas_sumadas= $a1." - ". $hora2;
$text=date('H:i:s', strtotime($horas_sumadas)) ;
谢谢你的帮助;)
