GB system encoding how to convert Utf-8

Code Utf-8

I try to use the Getid3 class Library from the MP3 file to extract the song information, most Chinese songs are normal, but a small number of files have garbled situation.

This is the extracted character, and it's Base64 encoded
Var_dump ($str, Base64_encode ($STR));
String (16) "Ðäëæ¿ñ³±"
String ("w5ddhmolw4bcv8oxwrpcsq==")

Detect character encoding, the result is CP936
Mb_detect_encoding ($str, ' GBK, gb2312, GB18030, Iso-8859-1, ASCII, UTF-8 ', true)

I try to convert this than coding, but the results are still not ideal
Mb_convert_encoding ($str, ' UTF-8 ', ' CP936 ')
String ("????") Donkey Hat lu Halogen "

Because CP936 and GBK are compatible with gb2312, the results are the same.

Reply to discussion (solution)

$s = "w5ddhmolw4bcv8oxwrpcsq==";
$s = base64_decode ($s);//ðäëæ¿ñ³± (this is UTF-8 encoded)
echo Utf8_decode ($s);//Heart like frenzy (note that this is GBK encoded)

Since your system does not recognize the GBK encoding, each extended ASCII character that makes up the GBK string is iso-8859-1 to utf-8 encoding conversion

You can write, too.
echo iconv (' GBK ', ' Utf-8 ', iconv (' Utf-8 ', ' latin1 ', $s));

It is also easy to determine if the Utf-8 encoding is 2 bytes
Echo (Ord ($s {0}) & 0xf0) = = 0xc0? ' Yes ': ' No ';

This should still have to be your server support some kind of code, you can do the conversion, if not supported, you cannot use the program to convert the
