Display an image if the value "7" is in the "Code" Row

Question

I appreciate the help you will offer me. I have tried many things, but now I am not moving forward at all. I managed to put this code but it doesn’t show me any picture.

Up on top of me

 $results = $query->fetchAll( PDO::FETCH_ASSOC );

And there on the table it comes like this:

  <?php foreach( $results as $row ){
    if($row['Codigos'] == 7 && $row['Maquinas'] == 5) {
 echo '<img src="/images/'.$photo->t1.png.'"/>';
    }
    ?>

In short... I will have a table with several possibilities, will be 3 columns in the table and the images will change every X minutes and if the value changes in the database, then will change the image inside the table also.

Thank you all again!
