您好,我要从我的 sql 打印时间总和,但我无法帮助我。
$SQL = "SELECT duration FROM core_network ";
$result = mysql_query($SQL);
$c_count='0';
$n="0";
$duration=array();
while ($db_field = mysql_fetch_array($result)) {
$duration[$n]= $db_field['duration'];
echo $duration[$n];
$n++;
$c_count++;
}
the result is 18:00:0000:39:0008:00:00
than i found the code from internet
function sum_the_time($Duration) {
$times = array('18:00:00','00:39:00','08:00:00');
$seconds = 0;
foreach ($times as $time)
{
list($hour,$minute,$second) = explode(':', $time);
$seconds += $hour*3600;
$seconds += $minute*60;
$seconds += $second;
}
$hours = floor($seconds/3600);
$seconds -= $hours*3600;
$minutes = floor($seconds/60);
$seconds -= $minutes*60;
// return "{$hours}:{$minutes}:{$seconds}";
return sprintf('%02d:%02d:%02d', $hours, $minutes, $seconds);
}
echo sum_the_time($duration);
如何输入 $duration[$n] 到 $times = array('18:00:00','00:39:00','08:00:00'); 而是多次
