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 numbe

Answer 1

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'];
