Convert seconds to Hour:Minute:Second

Question

I need to convert seconds to \"Hour:Minute:Second\".

For example: \"685\" converted to \"00:11:25\"

How can I achieve this?

Answer 1

One hour is 3600sec, one minute is 60sec so why not:

which produces:

$ php file.php
0:11:25

(I've not tested this much, so there might be errors with floor or so)
