// Using getid3 library, get duration
function get_duration($filename){

    $getID3 = new getID3;

    $file = $getID3->analyze($filename);

    $duration_string = $file['playtime_string'];

    // Format string to be 00:00:00
    return format_duration($duration_string);
}

// Format to AA::BB:CC
function format_duration($duration){

    // The base case is A:BB
    if(strlen($duration) == 4){
        return "00:0" . $duration;
    }
    // If AA:BB
    else if(strlen($duration) == 5){
        return "00:" . $duration;
    }   // If A:BB:CC
    else if(strlen($duration) == 7){
        return "0" . $duration;
    }
}
