我一直在努力工作一个小时左右,并且空白了.基本上我需要花费当前时间,增加30分钟,然后向下舍入到接下来的15分钟.
例子：
>如果现在是20:00,结果= 20:45
>如果它现在是20:10,结果= 20:45
>如果它现在是20:16,结果= 21:00
>如果现在是20:35,结果= 21:15
我的PHP生疏了,我一直在混淆日期添加和圆形方法试图让它工作,我知道它很简单 – 刚刚用完了想法！
谢谢
我还要添加一个解决方案：
<?PHP
date_default_timezone_set('America/Los_Angeles');
$times = array();
$times[] = strtotime('00:07');
$times[] = strtotime('04:21');
$times[] = strtotime('20:00');
$times[] = strtotime('20:10');
$times[] = strtotime('20:16');
$times[] = strtotime('20:35');
$times[] = strtotime('23:15');
foreach($times as $time) {
echo date('m-d-Y H:i',$time) . ' becomes ' . date('m-d-Y H:i:s',roundToNearestInterval($time)) . "<br />\n";
}
function roundToNearestInterval($timestamp)
{
$timestamp += 60 * 30;
list($m,$d,$y,$h,$i,$s) = explode(' ',date('m d Y H i s',$timestamp));
if ($s != 0) $s = 0;
if ($i < 15) {
$i = 15;
} else if ($i < 30) {
$i = 30;
} else if ($i < 45) {
$i = 45;
} else if ($i < 60) {
$i = 0;
$h++;
}
return mktime($h,$s,$m,$y);
}
产量：
03-01-2012 00:07 becomes 03-01-2012 00:45:00 03-01-2012 04:21 becomes 03-01-2012 05:00:00 03-01-2012 20:00 becomes 03-01-2012 20:45:00 03-01-2012 20:10 becomes 03-01-2012 20:45:00 03-01-2012 20:16 becomes 03-01-2012 21:00:00 03-01-2012 20:35 becomes 03-01-2012 21:15:00 03-01-2012 23:15 becomes 03-02-2012 00:00:00
