将时间格式从04:00更改为00:04:00

Question

I currently get duration in this format: 04:00 but I need in this format 00:04:00 .

I am using this code but it's not working correctly.

$time = date("h:i:s", strtotime($duration));
echo $time;

Answer 1

这样尝试

$duration = "00:"."04:00";

Answer 2

This should work for you:

(Your problem is in which format you read in your time, so DateTime::createFromFormat )

$date = DateTime::createFromFormat("i:s", "04:00");
echo $date->format('H:i:s');

Output:

00:04:00

Answer 3

The problem is the strtotime($duration) ; It doesn't know exactly what format that's in, and can't get a valid date from it. (This is why you're getting unexpected results from the date function.

If you want to just simply add 00: before $duration , you can do it like so:

$duration = '04:00';

$duration = '00:' . $duration;

You then would be able to pass this to the strtotime function, and would likely get better results.
