I want to echo 'yes' if the "notification" row value is 1

I tried to do with this code:

global $wpdb;
    $row =$wpdb->get_results("SELECT * FROM wp_users");
    if($row['notification'] == 1){
echo 'yes';
}

    Do you want to do this check for a currently logged in user? Currently, your SQL query pulls all of the users from wp_users table. – Greg Winiarski Aug 5 '19 at 13:42

    In your code $row is array of objects. To get for example login field from first result you should use $login = $row[0]->user_login;. Look here, get_results() returns array of objects or array of arrays. And the second thing, in users table there is no column notification. – nmr Aug 5 '19 at 13:50

As @nmr says, $row is an array of objects. You'll need to foreach these - and do the check in the foreach like this:

foreach ($row as $item) {
    if($item->notification == '1') {
        echo 'Yes';
    }
}

And there's no "notification" column as far as I know.

Also, can you explain what you're trying to achieve? Maybe there's an easier way to achieve your goal.

Best regards
