我刚刚在运行PHP 7.2和PhpMyAdmin的Apache2上安装了虚拟主机，现在我正在尝试从旧服务器导入数据库。当我在PhpMyAdmin上单击导入时，我收到此错误。
有人可以帮我解决这个问题吗？

嗨，以下内容绝对解决了我的相同问题(导入/导出等(：

所以。。。在 ubuntu 18.04、MySQL、php7.2 下
： 终端：sudo gedit/usr/share/phpmyadmin/libraries/plugin_interface.lib.php
找到以下行(ctrl+f(：
if ($options！= null && count($options(> 0( {
对我来说是在线#551
并更改以下内容：
if ($options！= null && count((array($options(> 0( {
Ctrl+s 用于保存更改
在终端中：Ctrl+C 用于取回程序...
以及：sudo systemctl restart apache2
"我认为在新的php版本中。它不能将 count(( 或 sizeof(( 与 un 数组类型一起使用。将参数强制到数组是解决此错误的简单方法,...">
感谢原作者解决问题！我试着分享它！
Open/usr/share/phpmyadmin/libraries/plugin_interface.lib.php(例如：sudo subl /usr/share/phpmyadmin/libraries/plugin_interface.lib.php(
转到第 551 行，
取代
if ($options != null && count($options) > 0) {
跟
if ($options != null && (is_array($options) || $options instanceof Countable) && count($options) > 0) {
在 Ubuntu 18.04 中为我工作
