把HH:MM:SS格式的时间字符串转换成秒数，可以使用date_parse函数解析具体的时间信息。
$time = "21:30:10";
$parsed = date_parse($time);
$seconds = $parsed["hour"] * 3600 + $parsed["minute"] * 60 + $parsed["second"];
echo $seconds;
?>
更详细的例子
转换成多少天/多少小时/多少分
function get_stay_time($timestamp, $is_hour = 1, $is_minutes = 1)
{
$CI =& get_instance();
if(empty($timestamp) || $timestamp <= 60) {
return false;
}
$time = time();
$remain_time = $time - $timestamp;
$day = floor($remain_time / (3600*24));
$day = $day > 0 ? $day."天" : "";
$hour = floor(($remain_time % (3600*24)) / 3600);
$hour = $hour > 0 ? $hour."小时" : "";
if($is_hour && $is_minutes) {
$minutes = floor((($remain_time % (3600*24)) % 3600) / 60);
$minutes = $minutes > 0 ? $minutes."分" : "";
return $day.$hour.$minutes;
}
if($hour) {
return $day.$hour;
}
return $day;
