How to convert a "HH:MM:SS" string to seconds with PHP?

Question

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;

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

$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:

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