Are there any best practices for handling character encoding issues in PHP?

Character encoding issues in PHP can be solved by ensuring that all strings are properly encoded and decoded using the correct encoding methods. One common practice is to use UTF-8 encoding for all strings to ensure compatibility across different systems and browsers. Additionally, using functions like mb_convert_encoding() can help convert strings to the desired encoding format.

// Convert string to UTF-8 encoding
$encoded_string = mb_convert_encoding($string, 'UTF-8', 'auto');
