How do I display a single entry from an array from MYSQL

$result = mysqli_query($conn, "SELECT * from $table");
          $pix = array();
          while ($row = $result->fetch_assoc()) {
           $pix[] = $row;
          }
          foreach ($pix as $pic) {
           echo "PID: {$pic['PID']}<br>"
            . "Title: {$pic['title']}<br>"
            . "Filename: {$pic['filename']}<br><br>";
          }
