Are there any recommended resources or documentation for handling character encoding issues in PHP?

Character encoding issues in PHP can occur when handling different character sets, such as UTF-8 or ISO-8859-1. To ensure proper handling of character encoding, it is recommended to use functions like mb_convert_encoding() or iconv() to convert strings between different encodings. Additionally, setting the appropriate charset in the HTTP headers and database connections can help prevent encoding problems.

// Example code snippet to convert a string to UTF-8 encoding
$string = "Hello, 你好";
$utf8_string = mb_convert_encoding($string, 'UTF-8', 'auto');
echo $utf8_string;
