Decode base64 string - php

Question

Is there any way to decode this string??

Actual string : 其他語言測試 - testing

base64 encode while sending on mail as subject as

\"=?iso-2022-jp?B?GyRCQj

Answer 1

What you are looking at is MIME header encoding. It can be decoded by mb_decode_mimeheader(), and generated by mb_encode_mimeheader(). For example:

其他語言測試 - testing

(The call to mb_internal_encoding() is necessary here because the contents of the subject line can't be represented in the default internal encoding of ISO8859-1.)
