Question

I have a function which converts seconds to the format of Hours:Minutes:Seconds

  function sec2hms ($sec) 
  {
    $hms = "";

    $hours = intval(intval($sec) / 3600); 
    $minutes = intval(($sec / 60) % 60); 
    $seconds = intval($sec % 60); 

    $hms .= str_pad($hours, 2, "0", STR_PAD_LEFT). ":";        
    $hms .= str_pad($minutes, 2, "0", STR_PAD_LEFT). ":";    
    $hms .= str_pad($seconds, 2, "0", STR_PAD_LEFT);

    return $hms;    
  }

How can I change this function so that all leading digits beyond the first minute position will be stripped?

For example

sec2hms(9) //returns 0:09
sec2hms(123) //returns 2:03
sec2hms(5941)//returns 1:39:01

Here’s the function I just wrote

function secondsToHHMMSS ($sec) 
{
    $hms = "";

    $hours = intval(intval($sec) / 3600); 
    $minutes = intval(($sec / 60) % 60); 
    $seconds = intval($sec % 60); 


    if($hours != 0){
    $hms .=  $hours . ":";
    $hms .=  str_pad($minutes, 2, "0", STR_PAD_LEFT) . ":";        
    $hms .= str_pad($seconds, 2, "0", STR_PAD_LEFT);
    }
    else{
    $hms .= $minutes . ":";
    $hms .= str_pad($seconds, 2, "0", STR_PAD_LEFT);
    }

    return $hms;    
}
