Are there any best practices for ensuring proper character encoding in PHP applications?

Improper character encoding can lead to issues such as garbled text or security vulnerabilities in PHP applications. To ensure proper character encoding, it is recommended to set the correct charset in the HTTP headers and use functions like mb_internal_encoding() to handle multibyte characters properly. 

// Set the correct charset in HTTP headers
header('Content-Type: text/html; charset=UTF-8');

// Set internal encoding to UTF-8
mb_internal_encoding('UTF-8');
