如何将“HH:MM:SS”转换为“HH:MM:SS”用PHP将字符串转换为秒？

是否有一种使用 PHP 5.3 将“HH:MM:SS”转换为秒的本机方法，而不是对冒号进行分割并将每个部分的相关数字相乘来计算秒？

例如，在 Python 中你可以这样做：

string time = "00:01:05";
double seconds = TimeSpan.Parse(time).TotalSeconds;

Is there a native way of doing "HH:MM:SS" to seconds with PHP 5.3 rather than doing a split on the colon's and multipling out each section the relevant number to calculate the seconds?

For example in Python you can do :

string time = "00:01:05";
double seconds = TimeSpan.Parse(time).TotalSeconds;

快速方法：

echo strtotime('01:00:00') - strtotime('TODAY'); // 3600

The quick way:

echo strtotime('01:00:00') - strtotime('TODAY'); // 3600

这应该可以解决问题：

list($hours,$mins,$secs) = explode(':',$time);
$seconds = mktime($hours,$mins,$secs) - mktime(0,0,0);

This should do the trick:

list($hours,$mins,$secs) = explode(':',$time);
$seconds = mktime($hours,$mins,$secs) - mktime(0,0,0);

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;

演示

函数date_parse()也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'];

demo

I think the easiest method would be to use strtotime() function:

$time = '21:30:10';
$seconds = strtotime("1970-01-01 $time UTC");
echo $seconds;

demo

Function date_parse() can also be used for parsing date and time:

$time = '21:30:10';
$parsed = date_parse($time);
$seconds = $parsed['hour'] * 3600 + $parsed['minute'] * 60 + $parsed['second'];

该功能还支持不带小时或分钟的输入

$timeInSecs = function ($tym) {
  $tym = array_reverse(explode(':',$tym));
  $hr = $tym[2] ?? 0;
  $min = $tym[1] ?? 0;
  return $hr*60*60 + $min*60 + $tym[0];
};

echo $timeInSecs('1:1:30') . '<br>'; // output: 3690
echo $timeInSecs('1:30') . '<br>'; // output: 90
echo $timeInSecs('30') . '<br>'; // output: 30

This function also supports input without hour or minute

$timeInSecs = function ($tym) {
  $tym = array_reverse(explode(':',$tym));
  $hr = $tym[2] ?? 0;
  $min = $tym[1] ?? 0;
  return $hr*60*60 + $min*60 + $tym[0];
};

echo $timeInSecs('1:1:30') . '<br>'; // output: 3690
echo $timeInSecs('1:30') . '<br>'; // output: 90
echo $timeInSecs('30') . '<br>'; // output: 30
