Convert time in HH:MM:SS format to seconds only?
提问by Ryan
How to turn time in format HH:MM:SSinto a flat seconds number?
如何将格式中的时间转换HH:MM:SS为平坦的秒数？
P.S.Time could be sometimes in format MM:SSonly.
PS时间有时可能MM:SS只是格式。

No need to explodeanything:
不需要explode任何东西：
$str_time = "23:12:95";
$str_time = preg_replace("/^([\d]{1,2})\:([\d]{2})$/", "00::", $str_time);
sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);
$time_seconds = $hours * 3600 + $minutes * 60 + $seconds;
And if you don't want to use regular expressions:
如果您不想使用正则表达式：
$str_time = "2:50";
sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);
$time_seconds = isset($hours) ? $hours * 3600 + $minutes * 60 + $seconds : $minutes * 60 + $seconds;

I think the easiest methodwould be to use strtotime()function:
我认为最简单的方法是使用strtotime()函数：
$time = '21:30:10';
$seconds = strtotime("1970-01-01 $time UTC");
echo $seconds;
// same with objects (for php5.3+)
$time = '21:30:10';
$dt = new DateTime("1970-01-01 $time", new DateTimeZone('UTC'));
$seconds = (int)$dt->getTimestamp();
echo $seconds;
Function date_parse()can also be used for parsing date and time:
函数date_parse()还可用于解析日期和时间：
$time = '21:30:10';
$parsed = date_parse($time);
$seconds = $parsed['hour'] * 3600 + $parsed['minute'] * 60 + $parsed['second'];
If you will parse format MM:SSwith strtotime()or date_parse()it will fail (date_parse()is used in strtotime()and DateTime), because when you input format like xx:yyparser assumes it is HH:MMand not MM:SS. I would suggest checking format, and prepend 00:if you only have MM:SS.
如果您将解析格式MM:SS，strtotime()否则date_parse()它将失败（date_parse()在strtotime()and 中使用DateTime），因为当您输入像xx:yy解析器这样的格式时假定它是HH:MM而不是MM:SS。我建议检查格式，00:如果你只有MM:SS.

If you have hours more than 24, then you can use next function (it will work for MM:SSand HH:MM:SSformat):
如果您的小时数超过 24，那么您可以使用下一个功能（它将适用于MM:SS和HH:MM:SS格式化）：
function TimeToSec($time) {
$sec = 0;
foreach (array_reverse(explode(':', $time)) as $k => $v) $sec += pow(60, $k) * $v;
return $sec;
}

In pseudocode:
在伪代码中：
split it by colon
seconds = 3600 * HH + 60 * MM + SS

$time = 00:06:00;
$timeInSeconds = strtotime($time) - strtotime('TODAY');

Try this:
尝试这个：
$time = "21:30:10";
$timeArr = array_reverse(explode(":", $time));
$seconds = 0;
foreach ($timeArr as $key => $value)
{
if ($key > 2) break;
$seconds += pow(60, $key) * $value;
}
echo $seconds;

You can use the strtotimefunction to return the number of seconds from today 00:00:00.
您可以使用该strtotime函数从 返回秒数today 00:00:00。
$seconds= strtotime($time) - strtotime('00:00:00');

Simple
简单的
function timeToSeconds($time)
{
$timeExploded = explode(':', $time);
if (isset($timeExploded[2])) {
return $timeExploded[0] * 3600 + $timeExploded[1] * 60 + $timeExploded[2];
}
return $timeExploded[0] * 3600 + $timeExploded[1] * 60;
}

<?php
$time = '21:32:32';
$seconds = 0;
$parts = explode(':', $time);
if (count($parts) > 2) {
$seconds += $parts[0] * 3600;
}
$seconds += $parts[1] * 60;
$seconds += $parts[2];
