Date Formatting: Your date format doesn't include seconds. If you want to include seconds, you should use 'Y-m-d H:i:s'.

Timezone: You're setting the timezone to 'Asia/Kolkata', but keep in mind that if your server is not in that timezone, you might get unexpected results. You may want to consider using UTC time to avoid timezone issues.

Return Format: You're returning the difference in the format of days, hours, and minutes, which is fine, but it's important to clarify what %d, %H, and %i represent in the format string.

public function differenceInHours($enddate)
{
    // Set timezone to Asia/Kolkata
    date_default_timezone_set('Asia/Kolkata');

    // Current date and time
    $current_date = date('Y-m-d H:i:s');

    // Start time
    $datetime1 = new DateTime($current_date);

    // End time
    $datetime2 = new DateTime($enddate);

    // Calculate the difference
    $interval = $datetime1->diff($datetime2);

    // Format the difference
    $formatted_diff = sprintf('%d days, %d hours, %d minutes', 
                                $interval->d, $interval->h, $interval->i);

    return $formatted_diff;
}
