What are the potential pitfalls of using different character encodings in PHP files and databases?

When using different character encodings in PHP files and databases, it can lead to issues with data consistency and display. To avoid this problem, it is important to ensure that all components are using the same character encoding, such as UTF-8, to maintain uniformity and prevent data corruption. 

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

// Set the character encoding for MySQL connection
mysqli_set_charset($conn, 'utf8');
