How can you optimize your PHP code to efficiently query a database for records within a specific time interval based on timestamps?

When querying a database for records within a specific time interval based on timestamps, you can optimize your PHP code by utilizing SQL's BETWEEN clause to filter records within the desired time range. This allows the database to efficiently retrieve only the necessary records without querying unnecessary data. 

// Set the start and end timestamps for the desired time interval
$startTimestamp = strtotime('2022-01-01 00:00:00');
$endTimestamp = strtotime('2022-01-31 23:59:59');

// Query the database for records within the specified time interval
$query = "SELECT * FROM your_table_name WHERE timestamp_column BETWEEN $startTimestamp AND $endTimestamp";
$result = mysqli_query($connection, $query);

// Process the retrieved records
if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        // Process each record as needed
    }
}
