为什么我不能显示我想要回应的所有特定列

This is my function

function getPdSectionChief(){
  /* get PD section Chief*/
  global $geotag_table, $wpdb, $current_user;
  $qry = "SELECT * FROM mirdc_pd_sectChief";
  $desc = $wpdb->get_results( $qry );
  return $desc;
}

after fetching, I am trying to show the data through my web

$geteeId = getPdSectionChief();
echo $geteeId->sect_id;

but it shows nothing :/ ..

but when i`am using the var_dump it show the array ..

Try something like this, based from here, don't really know if this is correct, I don't use mysqli but you can start from here

while ($row = $geteeId ->fetch_array(MYSQLI_NUM))
    {
        foreach ($row as $r)
        {
            print "$r ";
        }
        print "
";
    }
