How can timestamps be formatted and compared in PHP to delete entries from a database?

To delete entries from a database based on timestamps in PHP, you can format the timestamps using the `strtotime` function to convert them into Unix timestamps. Then, you can compare these timestamps to a specific date range and delete the entries that fall within that range.

// Assume $start_date and $end_date are the start and end dates of the range
$start_timestamp = strtotime($start_date);
$end_timestamp = strtotime($end_date);

// Delete entries from the database where the timestamp falls within the specified range
$query = "DELETE FROM table_name WHERE timestamp_column >= $start_timestamp AND timestamp_column <= $end_timestamp";
// Execute the query using your database connection
