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

Try encoding the string to UTF-8 first and then encode it to base 64. Same when decoding, decode the string from base64 and then from UTF-8. This is working for me:

php > $base = "其他語言測試 - testing";
php > $encoded = base64_encode(utf8_encode($base));
php > $decoded = utf8_decode(base64_decode($encoded));
php > echo ($decoded === $base) . "\n";
