How to format HH:MM:SS times if no leading zeros for hours, minutes , seconds php

Question

I have time string coming from an array and I want to add up leading zeros if it is not there for integer values below 10. For example I want

this "8:10:12"  to "08:10:12"
this "13:7:14"  to "13:07:14"
this "13:25:6"  to "13:25:06"

I can go for a really messy code with splitting by ":" and so on, But I would like to know if this can be done with clean code by one line. Just reply if this cannot be done with single line. I'll do the messy code then.

Thanks in advance..!

Perhaps take a look at how the array is defined, and make sure they're in two digits there? — Qirel, Oct 07 '17 at 09:11
`coming from an array`=> so try to adjust array before it's coming finally to you in the given format — Alive to die - Anant, Oct 07 '17 at 09:13

You can use php date function date with strtotime

$str = "8:10:12";
$new_str = date("H:i:s",strtotime($str));
echo $new_str;

You can use explode, array_map, sprintf, and implode to make it a one-liner, but it's not pretty.

$time = implode(':', array_map(function($num) { return sprintf("%02d", $num); }, explode(':', $time)));

See Formatting a number with leading zeros in PHP for other ways to format a number with leading zeroes.

Since that is a non standard time format you will have to parse it manually:

<?php
$data = ["8:10:12", "13:7:14", "13:25:6"];

array_walk($data, function(&$time) {
    preg_match('|^(\d+):(\d+):(\d+)$|', $time, $token);
    $time = (new DateTime())->setTime($token[1], $token[2], $token[3])->format("H:i:s");
});


print_r($data);

The output obviously is:

Array
(
    [0] => 08:10:12
    [1] => 13:07:14
    [2] => 13:25:06
)
