How to Fix \"count(): Parameter Must be an Array or an Object that Implements Countable\" Error in phpMyAdmin?

phpMyAdmin Error: "count(): Parameter Must be an Array or an Object that Implements Countable"

Have you encountered an error with phpMyAdmin stating "Warning in ./libraries/sql.lib.php#601ncount(): Parameter must be an array or an object that implements Countable"? Let's delve into the issue and provide a solution.

Cause of the Error:

The error arises from line 601 of the sql.lib.php file within the phpMyAdmin installation. This line checks if the variable $analyzed_sql_results['select_expr'] is an empty array or if it contains a single asterisk (*). However, due to a missing closing parenthesis, the count function always returns true, leading to the error.

Troubleshooting and Solution:

1. Edit the File:

   • Use the following command to open the file: sudo nano 613 /usr/share/phpmyadmin/libraries/sql.lib.php

2. Locate Line 613:

   • This line contains the erroneous count function.

3. Make the Replacement:

   • Replace the following section:
     ((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] == '*'))
     

4. Remove Extra Parenthesis:

   • On line 614, remove the last closing parenthesis: )

5. Restart Apache:

   • Execute the following command: sudo service apache2 restart

These steps should resolve the issue and eliminate the "count(): Parameter must be an array or an object that implements Countable" error within phpMyAdmin.
