What are some best practices for handling character encoding issues in PHP when migrating forum data?

Character encoding issues can arise when migrating forum data due to differences in character sets between databases or during the migration process. To handle this, it is important to ensure that all data is converted to a consistent character encoding, such as UTF-8, before inserting it into the new database. This can be done using PHP functions like mb_convert_encoding() or iconv().

// Convert forum data to UTF-8 encoding
$forumData = mb_convert_encoding($forumData, 'UTF-8', 'auto');
