Old Post 24 floor xuzuning's reply:
The Tip function should be written like this

function Tip ($code, $msg) {    $arr [' code '] = Iconv (' GB2312 ', ' UTF-8 ', $code);    $arr [' msg '] = iconv (' GB2312 ', ' UTF-8 ', $msg);         Die (Json_encode ($arr));}

Thank you! It did return, but there was a problem:

$ (". Tscg4"). HTML (DATA.MSG);

You pass a string constant to the tip function, so your program file is not utf-8?
What is your browser? What is the PHP version? I can't reproduce your phenomenon here.
Anyway, we need to see the tip output.

Your tip function can also be written.

function Tip ($code, $msg) {  $s = sprintf (' {"Code": "%s", "MSG": "%s"} ', $code, $msg);  Die (Iconv (' GBK ', ' utf-8 ', $s));}

Landlord's program files and is not UTF8?
Are there any additional pages ?
If not, first change to UTF8 test again.

Thanks for the reply, the Tip function is written so that Ajax can not return to the original page,
I said on the 2 floor of this post, is not found on the internet suitable, really useful conversion UTF-8 encoding to GB2312 function.
But my page has a tag in the head.

The program file is not utf-8, what does it mean? Refers to PHP files? SafeinfoAction.class.php or functions.php (inside the tip function)?
I open these two files, save as on the page there: Unicode normalization form: C (canonical decomposition, followed by canonical synthesis)

If your program file is Utf-8, then why $arr [' msg '] = iconv (' GB2312 ', ' UTF-8 ', $msg);?
