Solution to the problem of Chinese display in PHP JSON format,

The problem of Chinese display of returned json data

In the previous article, the Chinese returned in json format is displayed as u5723u8bdeu8282u5343u4e07u597du793cu5927u5949u9001

Solution 1:
Copy code The code is as follows:
function Notice(){
Include './include/conn.php'; //Database link file
$sql_notice = mysql_query('SELECT * FROM gg_notice where enable = "1" limit 0,10');
$notice = mysql_fetch_array($sql_notice, MYSQL_ASSOC);
$str = json_encode($notice);
//linux
return preg_replace("#\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\1')) ", $str);
//windows
//return preg_replace("#\u([0-9a-f]{4})#ie", "iconv('UCS-2LE', 'UTF-8', pack('H4', '\1' ))", $str);
 
}
?>

Copy code The code is as follows:
/**
* json generation, analysis supports Chinese
​*/
class Json_Helper {
/**
* Generate json
​​*/
Public static function encode($str){
          $json = json_encode($str);
           //linux
return preg_replace("#\u([0-9a-f]{4})#ie", "iconv('UCS-2BE', 'UTF-8', pack('H4', '\1')) ", $json);
            //windows
//return preg_replace("#\u([0-9a-f]{4})#ie", "iconv('UCS-2LE', 'UTF-8', pack('H4', '\1' ))", $json);
}

/**

Public static function decode($str) {
          return json_decode($str);
}
}
?>

When using the json_encode that comes with PHP to encode the data, the Chinese will become unicode, making it unreadable. For example: after json_encoding the string "Xiamen", the output is "u53a6u95e8".

After checking, there are two methods:
1. Restore "u53a6u95e8" to "Xiamen", use the following code:
Copy code The code is as follows:
$str= preg_replace("#\u([0-9a-f] )#ie", "iconv('UCS-2', 'UTF-8', pack('H4', '\1'))" , $str);

2. First urlencode and json_encode the Chinese field, and then use urldecode to display Chinese.
Copy code The code is as follows:
$code = urldecode(json_encode(urlencode("Xiamen")));

PHP version 5.4 has added a new option to Json: JSON_UNESCAPED_UNICODE. After adding this option, Chinese will not be automatically encoded.
Copy code The code is as follows:
echo json_encode("Xiamen", JSON_UNESCAPED_UNICODE);

In addition, since json_encode and json_decode only support UTF-8 encoded characters, GBK characters must be converted to JSON. Attached is the GBK to UTF-8 conversion code I wrote:
Copy code The code is as follows:
/*
​ GBK string transcoding is converted to UTF-8, and numbers are converted to numbers.
*/
function ct2($s){
If(is_numeric($s)) {
          return intval($s);
} else {
         return iconv("GBK","UTF-8",$s);
}
}
/*
Batch processing gbk->utf-8
*/
function icon_to_utf8($s) {

if(is_array($s)) {
foreach($s as $key => $val) {
$s[$key] = icon_to_utf8($val);
}
} else {
         $s = ct2($s);
}
Return $s;

}

echo json_encode(icon_to_utf8("Xiamen"));
