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?

Solution 1

You can try using

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

Demo

Solution 2

You could use the explode function in PHP:

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

Example: http://codepad.org/gAjZGtq3

Solution 3

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";

Solution 4

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;
}

I don't believe this is what the user is asking.

It takes his string as argument and returns seconds, just like he asked. Well, its up to him.

Maybe, provided the format can not be 42:12:02. That is assuming it's based on a 24 hour clock.

It works! But if I try to get value from mm:ss it returns negative value. :(
