求时间计算代码

[sir424]

从表中查出时间为字串型 $time="08:30:00"; 求PHP代码算出 $time+30（分钟）和 $time-30（分钟）

哥呀！这你自己写个时间处理类不就得了吧！不难吧！

$time_array=date_parse($time);
$min1 = $time_array['minute'] + 30;
$min2 = $time_array['minute'] - 30;

或者

$t = strtotime($time); //($t是Unix timestamp以秒为单位)
$t1 = $t + 30*60；
$t2 = $t - 30*60;
$time1 = getdate($t1);
$time2 = getdate($t2);

PHP code$time_array=date_parse($time);$min1=$time_array['minute']+30;$min2=$time_array['minute']-30;

或者

PHP code$t=strtotime($time);//($t是Unix timestamp以秒为单位)$t1=$t+30*60；$t2=$t-30*60;$time1=getdate($t1);$time2=getdate($t2);

就像这样吧。

[vnetworld]

$time = "08:30:00";
$time1 = date("H:i:s",strtotime("$time +30 minute"));
$time2 = date("H:i:s",strtotime("$time -30 minute"));
