Answer 1

I faced problem. My php version was 7.2 . Actually this error comes from a phpmyadmin library. The library name is /usr/share/phpmyadmin/libraries/sql.lib.php . In this file line no 614 . So you need to modify the file

From && ($analyzed_sql_results['select_expr'][0] == '*')))

to && ($analyzed_sql_results['select_expr'][0] == '*'))

or you can replace full method bellow:

/**
* Function to check whether to remember the sorting order or not
*
* @param array $analyzed_sql_results the analyzed query and other variables set
*                                    after analyzing the query
*
* @return boolean
*/
function PMA_isRememberSortingOrder($analyzed_sql_results)
{
return $GLOBALS['cfg']['RememberSorting']
    && ! ($analyzed_sql_results['is_count']
        || $analyzed_sql_results['is_export']
        || $analyzed_sql_results['is_func']
        || $analyzed_sql_results['is_analyse'])
    && $analyzed_sql_results['select_from']
    && ((empty($analyzed_sql_results['select_expr']))
        || (count($analyzed_sql_results['select_expr']) == 1)
            && ($analyzed_sql_results['select_expr'][0] == '*'))
    && count($analyzed_sql_results['select_tables']) == 1;
}

I hope this may help. Thank you.
