Die (json_encode (. no return

Die (json_encode (. didn't return my ajax code

$.post('{:U("Safeinfo/txpassadd")}', $("#txadd").serialize(), function(data) { alert("ok");...

Php code:

Tip ("100", 'transaction password cannot be the same as logon password! ');

function tip($code, $msg) {    $arr['code'] = iconv('GB2312', 'UTF-8', $code);    $arr['msg'] = iconv('GB2312', 'UTF-8', $msg);    //die(json_encode($arr));    die(var_json_encode($arr));  //cjq}function var_json_encode($var){  $_var = var_urlencode($var);  $_str = json_encode($_var);  return urldecode($_str); }

The alert ("OK") is not displayed on the result page. why is ajax not returned?

This cannot be done either:

function tip($code, $msg) {    $arr['code'] = iconv('GB2312', 'UTF-8', $code);    $arr['msg'] = iconv('GB2312', 'UTF-8', $msg);    die(json_encode($arr,JSON_UNESCAPED_UNICODE));  //cjq}

Why?

Reply to discussion (solution)

This is not the case :(

function tip($code, $msg) {    $arr['code'] = $code;    $arr['msg'] = $msg;    die(json_encode($arr,JSON_UNESCAPED_UNICODE));  //cjq}

$ _ Var = var_urlencode ($ var );
Where is this function defined?

$ _ Var = var_urlencode ($ var );

/*** Encode the variable or data using urlencode, so that the encoding for json_encode is not Chinese, prevention of json_encode failure * @ access private * @ param $ var * @ return array */function var_urlencode ($ var) {if (empty ($ var) {return false ;} if (is_array ($ var) {foreach ($ var as $ k => $ v) {if (is_scalar ($ v )) {// if is used to handle situations where the array is not $ var [$ k] = urlencode ($ v );} else {// else is used to process arrays $ var [$ k] = var_urlencode ($ v );}}} else {// used to process arrays $ var = urlencode ($ var);} return $ var ;}

UTF-8 encoded
{"Code": "100", "msg": "The transaction password cannot be the same as the login password! "}

It should be other issues
