Help Paano po ba kunin ang time in deduction po ni user using php and mysql?

[Jano-jano]

Hello po, sana meron makatulog. New b lang po sa php programming. Paano po ba kunin ang time in deduction sa attendance base po sa time_in po ni user.

Ex. May target po akong time_in which is 07:50 AM po. So kapag si user po ay lumagpas sa 07:51 AM until 8:00 AM may deduction na po syang 30 minutes sa kanyang oras.
if ever kong lumagpas na naman si user sa 8:01 AM until 9:00 AM 1 hour na po ang deduction. Paano po ba e calculate ang ganitong senario. Salamat po sa makatulong.

Hello po! Welcome to PHP programming. I can help you with calculating time deductions based on the user's time in.

To calculate the time deduction, you can follow these steps:

1. Get the current time and the user's time in:

$current_time = strtotime(date("H:i"));
$user_time_in = strtotime("07:50");

2. Calculate the time difference in minutes:

$time_difference = round(($current_time - $user_time_in) / 60);

3. Determine the deduction based on the time difference:

$deduction = 0;

if ($time_difference > 1 && $time_difference <= 10) {
    $deduction = 30; // 30 minutes deduction
} elseif ($time_difference > 10 && $time_difference <= 60) {
    $deduction = 60; // 1 hour deduction
}

4. Apply the deduction to the user's time:

$deducted_time = date("H:i", strtotime("-" . $deduction . " minutes", $user_time_in));

Here's the complete code:

$current_time = strtotime(date("H:i"));
$user_time_in = strtotime("07:50");

$time_difference = round(($current_time - $user_time_in) / 60);

$deduction = 0;

if ($time_difference > 1 && $time_difference <= 10) {
    $deduction = 30; // 30 minutes deduction
} elseif ($time_difference > 10 && $time_difference <= 60) {
    $deduction = 60; // 1 hour deduction
}

$deducted_time = date("H:i", strtotime("-" . $deduction . " minutes", $user_time_in));

echo "Deducted Time: " . $deducted_time;

Please note that this code assumes that the user's time in and the current time are on the same day. If you need to handle cases where the time in crosses over to the next day, you may need to add additional logic.

I hope this helps! Let me know if you have any further questions.
