How to convert a "HH:MM:SS" string to seconds with PHP?
提问by benjisail
Is there a native way of doing "HH:MM:SS" to secondswith PHP 5.3 rather than doing a split on the colon's and multipling out each section the relevant number to calculate the seconds?
是否有"HH:MM:SS" to seconds使用 PHP 5.3的本机方式，而不是在冒号上进行拆分并将每个部分乘以相关数字来计算秒数？
For example in Python you can do :
例如在 Python 中，您可以执行以下操作：
string time = "00:01:05";
double seconds = TimeSpan.Parse(time).TotalSeconds;

The quick way:
快捷方式：
echo strtotime('01:00:00') - strtotime('TODAY'); // 3600
回答by Spudley
This should do the trick:
这应该可以解决问题：
list($hours,$mins,$secs) = explode(':',$time);
$seconds = mktime($hours,$mins,$secs) - mktime(0,0,0);

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;
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'];

Unfortunately not - as PHP isn't strongly typed there's no concept of a time type and hence no means to convert between such a string and a "seconds" value.
不幸的是不是 - 因为 PHP 不是强类型的，所以没有时间类型的概念，因此无法在这样的字符串和“秒”值之间进行转换。
As such, in practice people often split the string and multiply out each section as you mentioned.
因此，在实践中，人们经常像您提到的那样拆分字符串并乘以每个部分。
