Output is in seconds. convert to hh:mm:ss format in php

Question

1. My output is in the format of 290.52262423327 seconds. How can i change this to 00:04:51?

2. The same output i want to show in seconds and in HH:MM:SS format, so if it is seconds, i want to show only 290.52 seconds.(only two integers after decimal point)? how can i do this?

I am working in php and the output is present in $time variable. want to change this $time into $newtime with HH:MM:SS and $newsec as 290.52.

Thanks :)

1)

function foo($seconds) {
  $t = round($seconds);
  return sprintf('%02d:%02d:%02d', ($t/3600),($t/60%60), $t%60);
}

echo foo('290.52262423327'), "\n";
echo foo('9290.52262423327'), "\n";
echo foo(86400+120+6), "\n";

prints

00:04:51
02:34:51
24:02:06

2)

echo round($time, 2);
