What are the implications of using BOM in PHP-generated files, and how can it impact the functionality of the code?

Using a Byte Order Mark (BOM) in PHP-generated files can cause issues such as outputting unexpected characters or headers already being sent errors. To avoid these problems, make sure to save your PHP files without a BOM. This can be done by configuring your text editor to save files in UTF-8 without a BOM.
