#1273 - 未知排序规则:'utf8mb4_unicode_ci' cPanel

2021-11-20 00:00:00 cpanel mysql wordpress phpmyadmin

我的本​​地机器上有一个 WordPress 数据库，我想将其传输到 cPanel 上的托管 phpMyAdmin.但是，当我尝试将数据库导入环境时，我不断收到此错误:

I have a WordPress database on my local machine that I want to transfer to a hosted phpMyAdmin on cPanel. However, when I try to import the database into the environment, I keep getting this error:

#1273 - Unknown collation: 'utf8mb4_unicode_ci'

我试过谷歌搜索，我能找到的唯一解决方案是这个 phpmysql error - #1273 - #1273 - Unknown collat​​ion: 'utf8mb4_general_ci' 到目前为止没有太大帮助.我已尝试清除 cookie，但仍然无法正常工作.请帮忙！

I have tried to Google around and the only solution I can find is this one phpmysql error - #1273 - #1273 - Unknown collation: 'utf8mb4_general_ci' which as by now isn't much help. I have tried clearing the cookies but it still won't work. Please help!

推荐答案

我遇到了同样的问题，因为我们所有的服务器都运行旧版本的 MySQL.这可以通过运行 PHP 脚本来解决.将此代码保存到文件中并输入数据库名称、用户和密码运行它，它会将排序规则从 utf8mb4/utf8mb4_unicode_ci 更改为 utf8/utf8_general_ci

I had the same issue as all of our servers run older versions of MySQL. This can be solved by running a PHP script. Save this code to a file and run it entering the database name, user and password and it'll change the collation from utf8mb4/utf8mb4_unicode_ci to utf8/utf8_general_ci

<form action="db-convert.php" method="post">

  dbuser: <input type="text" name="dbuser"><br>
  dbpass: <input type="text" name="dbpassword"><br>
  <input type="submit">
</form>

</body>
</html>
<?php
if ($_POST) {
  $dbname = $_POST['dbname'];
  $dbuser = $_POST['dbuser'];
  $dbpassword = $_POST['dbpassword'];

  $con = mysql_connect('localhost',$dbuser,$dbpassword);
  if(!$con) { echo "Cannot connect to the database ";die();}
  mysql_select_db($dbname);
  $result=mysql_query('show tables');
  while($tables = mysql_fetch_array($result)) {
          foreach ($tables as $key => $value) {
           mysql_query("ALTER TABLE $value CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci");
     }}
  echo "<script>alert('The collation of your database has been successfully changed!');</script>";
}

?>
