#1273-未知归类:'utf8mb4_unicode_ci'cPanel

mysql

我的本地计算机上有一个WordPress数据库,我想将其转移到cPanel上的托管phpMyAdmin。但是,当我尝试将数据库导入到环境中时,会不断出现此错误:

#1273 - Unknown collation: 'utf8mb4_unicode_ci'

我已尝试使用Google,但唯一可以找到的解决方案是此phpmysql错误-#1273-#1273-未知归类:’utf8mb4_general_ci’到目前为止,它并没有太大帮助。我曾尝试清除Cookie,但仍然无法正常工作。请帮忙!

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运行它,输入数据库名称,用户名和密码,它将归类从更改utf8mb4/utf8mb4_unicode_ciutf8/utf8_general_ci

<!DOCTYPE html>
<html>
<head>
  <title>DB-Convert</title>
  <style>
    body { font-family:"Courier New", Courier, monospace; }
  </style>
</head>
<body>

<h1>Convert your Database to utf8_general_ci!</h1>

<form action="db-convert.php" method="post">
  dbname: <input type="text" name="dbname"><br>
  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>";
}

?>
