phpmyadmin - count(): Parameter must be an array or an object that implements Countable

Edit file /usr/share/phpmyadmin/libraries/sql.lib.php using this command:

sudo nano +613 /usr/share/phpmyadmin/libraries/sql.lib.php

On line 613 the count function always evaluates to true since there is no closing parenthesis after $analyzed_sql_results['select_expr']. Making the below replacements resolves this, then you will need to delete the last closing parenthesis on line 614, as it's now an extra parenthesis.

Replace:

((empty($analyzed_sql_results['select_expr']))
    || (count($analyzed_sql_results['select_expr'] == 1)
        && ($analyzed_sql_results['select_expr'][0] == '*')))

With:

((empty($analyzed_sql_results['select_expr']))
    || (count($analyzed_sql_results['select_expr']) == 1)
        && ($analyzed_sql_results['select_expr'][0] == '*'))

Restart the server apache:

sudo service apache2 restart

The Easiest Method:

Just run this below command line in terminal and come back to PhpMyAdmin.

sudo sed -i "s/|\s*\((count(\$analyzed_sql_results\['select_expr'\]\)/| (\1)/g" /usr/share/phpmyadmin/libraries/sql.lib.php

Manual Method:

Open sql.lib.php file

nano /usr/share/phpmyadmin/libraries/sql.lib.php

Find for count($analyzed_sql_results['select_expr'] code on file. You can get this at line ~613. You can see this below wrong code

|| (count($analyzed_sql_results['select_expr'] == 1)

Just replace that wrong code with this below one

|| ((count($analyzed_sql_results['select_expr']) == 1)

Save the file and come to PhpMyAdmin.
