php - convert Hour:Minute:Second. to second

Question

I need to convert Hour:Minute:Second to second (for example 00:02:05 = 125s). Is there any build in function in PHP to this or need to do some math?

the DateInterval class sadly has no function for that, so you will have to do the math — x4rf41, Jul 01 '13 at 15:18
Questions must demonstrate a minimal understanding of the problem being solved. Tell us what you've tried to do, why it didn't work, and how it should work.

Is this format based on 24 hours or is can it run past 24 hours, e.g. `42:12:02`? — Jason McCreary, Jul 01 '13 at 15:25

You can try using

strtotime('00:02:05') - strtotime('today'); //125

I don't believe this is what the user is asking. – Jason McCreary Jul 01 '13 at 15:19

It takes his string as argument and returns seconds, just like he asked. Well, its up to him. – mr. Pavlikov Jul 01 '13 at 15:20
Maybe, provided the format can not be `42:12:02`. That is *assuming* it's based on a 24 hour clock. – Jason McCreary Jul 01 '13 at 15:22
It works! But if I try to get value from **mm:ss** it returns negative value. :( – Resalat Haque Jul 01 '13 at 15:31

You could use the explode function in PHP:

function seconds($time){
$time = explode(':', $time);
return ($time[0]*3600) + ($time[1]*60) + $time[2];
}

strtotime could help. Documentation.

Alternatively,

<?php
$parts = explode(":", $my_str_time); //if you know its safe
$answer = ($parts[0] * 60 * 60 + $parts[1] * 60 + $parts[2]) . "s";

There may be something in the DateTime class. But there is no single method. In addition, you'd need to convert your format to a date time object, then back again.

It's trivial to write your own:

function toSeconds($hours, $minutes, $seconds) {
    return ($hours * 3600) + ($minutes * 60) + $seconds;
}
