PHP json encode - Malformed UTF-8 characters, possibly incorrectly encoded
提问by sparkmix
I'm using json_encode($data)to an data array and there's a field contains Russian characters.
我正在使用json_encode($data)数据数组，并且有一个字段包含俄语字符。
I used this mb_detect_encoding()to display what encoding it is for that field and it displays UTF-8.
我用它mb_detect_encoding()来显示该字段的编码方式，并显示 UTF-8。
I think the json encode failed due to some bad characters in it like "ра?". I tried alot of things utf8_encodeon the data and it will by pass that error but then the data doesn't look correct anymore.
我认为 json 编码失败是因为里面有一些不好的字符，比如“ра?”。我utf8_encode在数据上尝试了很多东西，它会绕过那个错误，但是数据看起来不再正确了。
What can be done with this issue?
这个问题可以做什么？

The issue happens if there are some non-utf8 characters inside even though most of them are utf8 chars. This will remove any non-utf8 characters and now it works.
如果里面有一些非 utf8 字符，即使其中大部分是 utf8 字符，也会出现问题。这将删除任何非 utf8 字符，现在它可以工作了。
$data['name'] = mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');

If you have a multidimensional array to encode in JSON format then you can use below function:
如果您有一个多维数组以 JSON 格式编码，那么您可以使用以下函数：
If JSON_ERROR_UTF8 occurred :
如果发生 JSON_ERROR_UTF8 ：
$encoded = json_encode( utf8ize( $responseForJS ) );
Below function is used to encode Array data recursively
下面的函数用于递归编码数组数据
/* Use it for json_encode some corrupt UTF-8 chars
* useful for = malformed utf-8 characters possibly incorrectly encoded by json_encode
*/
function utf8ize( $mixed ) {
if (is_array($mixed)) {
foreach ($mixed as $key => $value) {
$mixed[$key] = utf8ize($value);
}
} elseif (is_string($mixed)) {
return mb_convert_encoding($mixed, "UTF-8", "UTF-8");
}
return $mixed;
}

Please, make sure to initiate your Pdo object with the charset iso as utf8. This should fix this problem avoiding any re-utf8izing dance.
请确保使用字符集 iso 作为 utf8 启动您的 Pdo 对象。这应该可以解决这个问题，避免任何重新 utf8izing 的舞蹈。
$pdo = new PDO("mysql:host=localhost;dbname=mybase;charset=utf8", 'user', 'password');
回答by M.Bilal Murtaza
you just add in your pdo connection charset=utf8like below line of pdo connection:
您只需添加您的 pdo 连接charset=utf8如下面的 pdo 连接：
$pdo = new PDO("mysql:host=localhost;dbname=mybase;charset=utf8", 'user', 'password');
hope this will help you

I know this is kind of an old topic, but for me it was what I needed. I just needed to modify the answer 'jayashan perera'.
我知道这是一个古老的话题，但对我来说这是我需要的。我只需要修改答案'jayashan perera'。
//...code
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
for ($i=0; $i < sizeof($result) ; $i++) {
$tempCnpj = $result[$i]['CNPJ'];
$tempFornecedor = json_encode(html_entity_decode($result[$i]['Nome_fornecedor']),true) ;
$tempData = $result[$i]['efetivado_data'];
$tempNota = $result[$i]['valor_nota'];
$arrResposta[$i] = ["Status"=>"true", "Cnpj"=>"$tempCnpj", "Fornecedor"=>$tempFornecedor, "Data"=>"$tempData", "Nota"=>"$tempNota" ];
}
echo json_encode($arrResposta);
And no .js i have use
没有 .js 我用过
obj = JSON.parse(msg);

Remove HTML entities before JSON encoding. I used html_entity_decode()in PHP and the problem was solved
在 JSON 编码之前删除 HTML 实体。我html_entity_decode()在PHP中使用，问题解决了
$json = html_entity_decode($source);
$data = json_decode($json,true);
