How can one effectively add times exceeding 24 hours in PHP, as discussed in the thread?

When adding times exceeding 24 hours in PHP, we can convert the times to seconds, perform the addition, and then convert the result back to hours, minutes, and seconds. This allows us to handle durations that surpass a single day effectively. 

function addTimes($time1, $time2) {
    $seconds1 = strtotime($time1) - strtotime('TODAY');
    $seconds2 = strtotime($time2) - strtotime('TODAY');
    
    $totalSeconds = $seconds1 + $seconds2;
    
    $hours = floor($totalSeconds / 3600);
    $minutes = floor(($totalSeconds % 3600) / 60);
    $seconds = $totalSeconds % 60;
    
    return sprintf('%02d:%02d:%02d', $hours, $minutes, $seconds);
}

// Example usage
$time1 = '26:30:15';
$time2 = '12:45:30';

echo addTimes($time1, $time2); // Output: 39:15:45
