Parameter Must be an Array or an Object that Implements Countable

Question:

When attempting to open a table in phpMyAdmin, you may encounter the following error:

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

This can be a perplexing issue, especially since it originates within the phpMyAdmin interface.

Answer:

The error stems from a mismatch between phpMyAdmin and the underlying PHP version (7.2) on Ubuntu 16.04. To resolve this issue, follow these steps:

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

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

   Copy after login

2. On line 613, replace the following code:

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

   Copy after login

   with this corrected code:

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

   Copy after login
3. Additionally, delete the last closing parenthesis on line 614.

4. Finally, restart the Apache server:

   sudo service apache2 restart

   Copy after login

This adjustment will align the count function with the PHP 7.2 syntax, preventing the error from occurring in phpMyAdmin.
