Laravel malformed character UTF-8
提问by Kaizokupuffball
When I try to grab a list of all directories and use the list in a JSON response, I get the error that the response has malformed UTF-8 characters.
I know I have letters like "? ? ?" in the directories. When I use dd($directories)I can see a "b" infront of every directory that contains a "? ? ?" letter (as you can see in the photo).
当我尝试获取所有目录的列表并在 JSON 响应中使用该列表时，我收到错误消息，即响应的 UTF-8 字符格式错误。我知道我有像“？？？”这样的字母 在目录中。当我使用时，dd($directories)我可以看到每个包含“? ? ?”的目录前面都有一个“b”。信（如您在照片中所见）。
I tried to use this, but this does not work either.
return response() -> json($movies, 200, ['Content-type'=> 'application/json; charset=utf-8'], JSON_UNESCAPED_UNICODE);
我尝试使用它，但这也不起作用。
return response() -> json($movies, 200, ['Content-type'=> 'application/json; charset=utf-8'], JSON_UNESCAPED_UNICODE);
Edit: This is the code I have for now.
编辑：这是我现在的代码。
$drives = ['M1', 'M2', 'M3', 'M4'];
$movies =[];
foreach ($drives as $drive) {
$disk = Storage::disk($drive);
foreach ($disk -> directories() as $movie) {
$movies[] = $movie;
}
}
return response() -> json($movies, 200, ['Content-type'=> 'application/json; charset=utf-8'], JSON_UNESCAPED_UNICODE);

You are using strings that are coming from the filesystem filenames. Such strings are typcally not in UTF-8 and use the ISO-8859-1 (usually). Coincidentally this is the required input encoding which utf8_encoderequires to work.
您正在使用来自文件系统文件名的字符串。此类字符串通常不在 UTF-8 中并使用 ISO-8859-1（通常）。巧合的是，这是utf8_encode工作所需的输入编码。
$drives = ['M1', 'M2', 'M3', 'M4'];
$movies =[];
foreach ($drives as $drive) {
$disk = Storage::disk($drive);
foreach ($disk -> directories() as $movie) {
$movies[] = utf8_encode($movie);
}
}
return response() -> json($movies, 200, ['Content-type'=> 'application/json; charset=utf-8'], JSON_UNESCAPED_UNICODE);
However, if you do wish to convert to UTF-8 from another (known) encoding you need to use mb_convert_encoding($str,"UTF-8",$from_encoding). Overall be aware that setting the HTTP response encoding to UTF-8 will not automatically convert any character encodings. You have to do that manually.
但是，如果您确实希望从另一种（已知）编码转换为 UTF-8，则需要使用mb_convert_encoding($str,"UTF-8",$from_encoding). 请注意，将 HTTP 响应编码设置为 UTF-8 不会自动转换任何字符编码。您必须手动执行此操作。
