change default collation in phpmyadmin

问题

It seems to me that phpMyAdmin imports tables by default with collation latin1_swedish_ci, how i change this?

回答1:

In your Mysql configuration change the default-character-set operative under the [mysqld] tab. For example:

[mysqld]
default-character-set=utf8

Don't forget to restart your Mysql server afterwards for the changes to take effect.

For Linux:

You need to have access to the MySQL config file.
The location can vary from /etc/mysql/my.cnf to ~/my.cnf (user directory).

Add the following lines in the section [mysqld]:

collation_server = utf8_unicode_ci
character_set_server=utf8

Restart the server:
```
service mysqld restart
```

This is not a phpMyAdmin question.

Collations are part of recent MySQL releases, you must set the default collation of the server (or at least of the database) to change that behaviour.

To convert already imported tables to UTF-8 you can do (in PHP):

$dbname = 'my_databaseName';
mysql_connect('127.0.0.1', 'root', '');
mysql_query("ALTER DATABASE `$dbname` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci");
$res = mysql_query("SHOW TABLES FROM `$dbname`");
while($row = mysql_fetch_row($res)) {
   $query = "ALTER TABLE {$dbname}.`{$row[0]}` CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci";
   mysql_query($query);
   $query = "ALTER TABLE {$dbname}.`{$row[0]}` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci";
   mysql_query($query);
}
echo 'all tables converted';

know this is an old post. But the way i changed the default charset through phpMyAdmin was:

phpMyadmin main page > Variables tab (Server variables and settings) > searched for "character" and changed all variables from "latin1" to "utf8". (on a MAMP installation with phpMyAdmin v. 3.5.7)

And as the others said, this is the variables for MySQL and not some phpMyAdmin specific ones.

回答5:

For utf8mb4, add/change the following in the [mysqld] section:

collation_server = utf8mb4_unicode_ci
character_set_server = utf8mb4

Then restart the mysql service (for Ubuntu the command is sudo service mysql restart)

回答6:

MySQL DB « change Collation Name of a Database|Table to utf8_general_ci inorder to support Unicode.

Change Configuration settings file also

XAMPP: uncomment UTF 8 Settings from the Configuration settings file « D:\xampp\mysql\bin\my.ini

## UTF 8 Settings
#init-connect=\'SET NAMES utf8\'
collation_server=utf8_unicode_ci
character_set_server=utf8
skip-character-set-client-handshake
character_sets-dir="D:/xampp/mysql/share/charsets"

For MySQL server to support UTF8 and the below line of code in file my.cnf

## UTF 8 Settings
collation_server=utf8_unicode_ci
character_set_server=utf8

@see

XAMPP - Apache Virtual Host Setting
XAMPP security concept - Error 403,404

回答7:

Insert this strings into my.ini (or my.cnf)

[mysqld]
collation_server = utf8_unicode_ci
character_set_server=utf8

Add into config.inc.php

$cfg['DefaultConnectionCollation'] = 'utf8_general_ci';

You need to restart MySQL server and remove cookies,data for domain where is located PhpMyAdmin
Reload page with PhpMyAmdin and at look the result

回答8:

I wanted to use utf8mb4 instead, and the configuration had to be the following:

collation_server = utf8mb4_general_ci
character_set_server=utf8mb4

the server would not start if the character_set was set to utf8
