How can developers ensure that PHP files are saved in UTF-8 format to prevent issues with special characters during file operations?

When saving PHP files, developers can ensure they are in UTF-8 format by configuring their text editor to save files in UTF-8 encoding by default. This will prevent issues with special characters during file operations such as reading, writing, or manipulating strings. 

// Set UTF-8 encoding for PHP files
header('Content-Type: text/html; charset=UTF-8');
mb_internal_encoding('UTF-8');
