In PHP, what are some strategies for efficiently handling and updating database entries based on time-sensitive criteria, such as resetting values after a certain duration?

When handling time-sensitive criteria in database entries, one efficient strategy is to use scheduled tasks or cron jobs to periodically check and update the entries based on the specified criteria. For example, you can reset values after a certain duration by comparing the current timestamp with the timestamp of when the entry was created or last updated. 

// Check and update database entries based on time-sensitive criteria
$currentTimestamp = time();
$duration = 3600; // 1 hour in seconds

// Query database to retrieve entries that need to be updated
$query = "SELECT * FROM your_table WHERE last_updated < ($currentTimestamp - $duration)";
$result = mysqli_query($connection, $query);

// Update the entries that meet the criteria
while ($row = mysqli_fetch_assoc($result)) {
    // Reset values or perform necessary updates
    $id = $row['id'];
    $updateQuery = "UPDATE your_table SET value = 'reset_value' WHERE id = $id";
    mysqli_query($connection, $updateQuery);
}

// Close database connection
mysqli_close($connection);
