Convert Digit Time to seconds

Question

How can I convert a digit time into seconds?

I need to compare the time so I though that it is easier to convert the digit time to seconds and compare the seconds later on.

for example:

00:00:33
00:01:33
02:01:33

@Panda - the solution on that page while compact, is subject to inaccuracies due to the first `strtotime()` time being slightly different than the second `strtotime()` as it is processed in sequential order. It is good in most cases where precision isn't a priority and where server load is minimal. — Kraang Prime, Jan 05 '17 at 08:46
Lots of answers, but no one questioning *why* you want to do this. Time strings are already comparable as they are. Equality and comparison operators already work as expected when applied to the strings themselves. — Phylogenesis, Jan 05 '17 at 10:08

You can write a custom parser if you are looking for precise seconds from that format.

Something like this should do the trick :

echo hhmmss2seconds("18:24:35");

function hhmmss2seconds($time) {
    $digits = explode(":", $time);
    $seconds = 0;
    $seconds = $seconds + intval($digits[0]) * 3600; // hours
    $seconds = $seconds + intval($digits[1]) * 60; // minutes
    $seconds = $seconds + intval($digits[2]); // seconds    
    return $seconds;
}

You want to use strtotime(). This converts "digit time" to Unix time.

$time_in_seconds = strtotime('00:00:33');

strange if I do this $test = strtotime(00:00:33); echo $test . '
'; I get an unexpected ":" – utdev Jan 05 '17 at 08:39
hmm I do not get an error now but it returns me this : 1483570833 – utdev Jan 05 '17 at 08:41
The parameter of `strtotime()` needs to be a string so like this: `echo $test = strtotime("00:00:33");` – Jan 05 '17 at 08:41
I modified it so it is encapsulated in quotes, however the result of strtotime is incorrect. [proof it is not valid](http://sandbox.onlinephpfunctions.com/code/bcbf099cd6927f664aebb6f4fbe7372d50de9afe) – Kraang Prime Jan 05 '17 at 08:42

Try this:

echo strtotime("1970-01-01 00:00:11  UTC");

Try This its working

 <?php
    function time_to_seconds($time) { 
        list($h, $m, $s) = explode(':', $time); 
        return ($h * 3600) + ($m * 60) + $s; 
    }
    echo time_to_seconds("00:00:33");
    echo time_to_seconds("00:01:33");
