• The mb_preferred_mime_name() function depends on the mbstring extension, so you need to make sure that the extension is enabled before using the function.

• This function is mainly used to obtain the MIME name corresponding to the character set encoding, which is convenient for use in scenarios such as generating HTTP header information or processing file uploads.
