解決phpmyadmin出現的警告訊息Warning in ./libraries/sql.lib.php#613

       最近在xubuntu 18.04 LTS 安裝 apache2、php 7.2、phpmyadmin與 MariaDB。當我進入phpmyadmin，出現這樣的錯誤訊息：

Warning in ./libraries/sql.lib.php#613
 count(): Parameter must be an array or an object that implements Countable

解決方式：

1.備份sql.lib.php

$sudo cp /usr/share/phpmyadmin/libraries/sql.lib.php /usr/share/phpmyadmin/libraries/sql.lib.php.bak 

2.編輯sql.lib.php

$sudo geany /usr/share/phpmyadmin/libraries/sql.lib.php 

3.將 (count($analyzed_sql_results['select_expr'] == 1) 改為((count($analyzed_sql_results['select_expr']) == 1)，實際上只是要新增個括號 )

4.儲存
