由于PHP / 5.4.0有一个选项称为JSON_UNESCAPED_UNICODE。查看：

http：//se2.php。 net / json_encode

因此，您应该尝试：

  json_encode（$ text，JSON_UNESCAPED_UNICODE）; 
 

I have a PHP script that deals with a wide variety of languages. Unfortunately, whenever I try to use json_encode, any Unicode output is converted to hexadecimal entities. Is this the expected behavior? Is there any way to convert the output to UTF-8 characters?

Here's an example of what I'm seeing:

INPUT

echo $text;

OUTPUT

База данни грешка.

INPUT

json_encode($text);

OUTPUT

"\u0411\u0430\u0437\u0430 \u0434\u0430\u043d\u043d\u0438 \u0433\u0440\u0435\u0448\u043a\u0430."

Since PHP/5.4.0, there is an option called "JSON_UNESCAPED_UNICODE". Check it out:

http://se2.php.net/json_encode

Therefore you should try:

json_encode( $text, JSON_UNESCAPED_UNICODE );
