is this code efficient?

PHP Code:

                while ($project_info = $DB_site->fetch_array($projects))
                 {
                     $project_info['text'] = nl2br(stripslashes($project_info['text']));
                     extract($project_info);
                     $time_posted = vbdate('n-j-y, g:i:s a', $timestamp);
                     // selects the number of times each confeession was rated
                     $number_of_rates = $DB_site->query_first("SELECT COUNT(*) AS votes
                     FROM project_rate
                     WHERE projectid = $projectid
                     ");
                     $num_rates = number_format($number_of_rates['votes']);
                     // selects the username of the person who made the confeession
                     $who_done_it = $DB_site->query_first("SELECT username
                     FROM user
                     WHERE userid = $project_info[userid]
                     ");
