What are the dangers of using hardcoded byte formats in the pack() function in PHP, and how can they be mitigated for better code flexibility?

Using hardcoded byte formats in the pack() function can make the code less flexible and harder to maintain because any changes to the byte format would require manual updates in multiple places. To mitigate this issue, it is recommended to define the byte format as a constant or variable that can be easily updated in one place. 

<?php
// Define byte format as a constant
define('BYTE_FORMAT', 'C4');

// Use the constant in the pack() function
$data = pack(BYTE_FORMAT, 1, 2, 3, 4);
