php json_encode 将日语字符转换为 UTF-8 [英] Convert Japanese characters to UTF-8 for php json_encode

问题描述

我的(UTF-8 编码)数据库利用规约"中有一个日语字符串，它被传递给 php 的 json_encode 函数并收到此警告:

I have a Japanese string in my (UTF-8 encoded) database '利用規約' which is passed to php's json_encode function and receive this warning:

PHP 警告:json_encode():参数中的 UTF-8 序列无效

PHP Warning: json_encode(): Invalid UTF-8 sequence in argument

有没有办法将其转换为有效的 UTF-8 以避免这种情况?如果db是utf-8，为什么php的字符串会有问题?

Is there a way to convert this to valid UTF-8 in order to avoid this? If the db is utf-8 why would php have a problem with the string?

更新:

事实证明该错误实际上是由于几行前 sprintf 和多字节字符的问题造成的.

Turns out the error was in fact due to a problem with sprintf and multibyte characters a couple lines earlier.

推荐答案

utf8_encode 应该适合你.

utf8_encode should work for you.

http://www.php.net/manual/en/function.utf8-encode.php

如果 utf8_encode 不起作用，请尝试 mb_convert_encoding:

If utf8_encode doesn't work, try mb_convert_encoding:

mb_convert_encoding($string,"UTF-8","auto");
