問題描述

目前我們在 PHP 中使用以下命令將字符集設置為 UTF-8 在我們的應用程序中.

Currently we are using the following commands in PHP to set the character set to UTF-8 in our application.

由于這有點開銷，我們希望將其設置為 MySQL 中的默認設置.我們可以在/etc/my.cnf 或其他位置執行此操作嗎?

Since this is a bit of overhead, we'd like to set this as the default setting in MySQL. Can we do this in /etc/my.cnf or in another location?

SET NAMES 'utf8'
SET CHARACTER SET utf8

我在/etc/my.cnf 中尋找了默認字符集，但沒有關于字符集的內容.

I've looked for a default charset in /etc/my.cnf, but there's nothing there about charsets.

此時，我執行以下操作將 MySQL 字符集和排序規則變量設置為 UTF-8:

At this point, I did the following to set the MySQL charset and collation variables to UTF-8:

skip-character-set-client-handshake
character_set_client=utf8
character_set_server=utf8

這是處理這個問題的正確方法嗎?

Is that a correct way to handle this?

推薦答案

要設置默認為UTF-8，需要在my.cnf/my.ini中添加以下內容

To set the default to UTF-8, you want to add the following to my.cnf/my.ini

[client]
default-character-set=utf8mb4

[mysql]
default-character-set=utf8mb4


[mysqld]
collation-server = utf8mb4_unicode_520_ci
init-connect='SET NAMES utf8mb4'
character-set-server = utf8mb4

如果您想更改現有數據庫的字符集，請告訴我...您的問題沒有直接指定它，所以我不確定這是否是您想要做的.

If you want to change the character set for an existing DB, let me know... your question didn't specify it directly so I am not sure if that's what you want to do.

由于 utf8 只是 UTF-8 的一個子集，我在原始答案中用 utf8mb4 替換了 utf8.MySQL 和 MariaDB 都調用 UTF-8 utf8mb4.

I replaced utf8 with utf8mb4 in the original answer due to utf8 only being a subset of UTF-8. MySQL and MariaDB both call UTF-8 utf8mb4.
