phpmyadmin 可在 Ubuntu 20.04 上适用于 php 5.6 和 7.2

Question

我正在使用 Ubuntu 20.04，安装了多个 PHP 版本（5.6 - 8.0），因为我需要同时使用 Magento 1 和 2。当我切换到 7.2 并在 URL 中打开 PHPMyAdmin 时，它可以正常工作。

但是当我尝试切换到 PHP 5.6 并刷新 URL 中的 PHPMyAdmin 页面时，页面变为空白。我尝试了一些解决方案（如附件所示），但没有效果。

[mysql]
default-character-set=utf8

[mysqld]
collation-server = utf8_unicode_ci
character-set-server = utf8
default-authentication-plugin=mysql_native_password

my.cnf 更改

mysql> 
mysql> use mysql;
Database changed
mysql> 
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root@123';

mysql 更改

然后我重新启动了 MySql 和 Apache2。您能在这方面帮助我吗？

提前致谢。
