I tried that message and the class extracted the subject correctly. What is your difficulty?

manuel,it is my problem,my page charset is utf-8,so when i use iconv function.
iconv("gb2312","utf-8",$results['Subject']);
the result is correct.

but there is a new problem here .
Subject: =?gb2312?B?dGVzdC4uLi4ujqeDyYKAuL28/rXE?=

echo iconv("gb2312","utf-8",base64_decode(dGVzdC4uLi4ujqeDyYKAuL28/rXE))." <br>";
Warning: Division by zero .

the subject extract is incorrect,why?????????




thank you very very very much!

The class decodes the subject for you. There is no need to use iconv function.

Just look at the Subject and SubjectEncoding entries of the array returned by the Analyze function.
