How can PHP scripts efficiently differentiate between different time intervals for phone redirection based on data in an SQLite database?

To efficiently differentiate between different time intervals for phone redirection based on data in an SQLite database, you can store the start and end times for each interval in the database and then query the database to determine which interval the current time falls within. This can be achieved by using SQL queries to retrieve the relevant data and then comparing the current time to the start and end times of each interval. 

// Connect to SQLite database
$db = new SQLite3('database.db');

// Get current time
$current_time = time();

// Query database to retrieve phone redirection intervals
$query = "SELECT * FROM phone_redirection_intervals";
$result = $db->query($query);

// Loop through intervals to find the appropriate one
while ($row = $result->fetchArray()) {
    $start_time = strtotime($row['start_time']);
    $end_time = strtotime($row['end_time']);
    
    if ($current_time >= $start_time && $current_time <= $end_time) {
        // Perform phone redirection for this interval
        redirectPhone($row['phone_number']);
        break;
    }
}

// Close database connection
$db->close();

function redirectPhone($phone_number) {
    // Code to redirect phone to the specified number
}
