问题描述

我想将JSON对象转换为字符串.当我使用json_encode时，我得到一个字符串，但全部带有十六进制字母.我想将其转换为UTF-8.换句话说，我想看角色.我该怎么办?

I want to convert a JSON object into a string. when I am using json_encode I get a string but all with hex letters. I want to convert it to a UTF-8. In other words I want to see the characters. How do I do it?

推荐答案

我正在使用json_encode将数据(例如阿拉伯字符)存储在MySQL字段中.

I was using json_encode to store data such as Arabic Characters in MySQL fields.

它将像这样以十六进制形式存储阿拉伯字符:

It would store the Arabic characters as HEX within the Database like this:

u0644 u063a ...

u0644 u063a...

这是不正确的.您必须确保用mysql_escape_string()包装json_encode.

Which is incorrect. You must ensure that you wrap your json_encode with mysql_escape_string().

这将确保将数据按以下方式放入MySQL:

This will make sure that the data is put in MySQL as:

\ u0644 \ u063a ...

\u0644\u063a...

然后，当您使用json_decode时，它将十六进制字符串转换为UTF-8并正确输出.

Then, when you use json_decode, it converts the HEX strings into UTF-8 and is output correctly.
