PHP Integrating PHP with Databases Using Relational Tables Understanding SQL Injections

SQL Injection Not Working?

For the fun of better understanding how SQL injections work, I decided to try an SQL injection of my own but it won't work.

I copied Alena's SQL injection exactly as is, but nothing happens? WHY?

details.php?id=2;DROP TABLE Media

I am using phpMyAdmin database via XAMPP and my project is being served on localhost. Not sure if this makes a difference?

mistake when she adds media_id to the single_item_array function. the function should have Media.media_id on the select.

function single_item_array($id){
    $results = $db->query("SELECT Media.media_id, title, category, img, format, year, 
          publisher, isbn, genre
          FROM Media
          JOIN Genres ON Media.genre_id=Genres.genre_id
          LEFT OUTER JOIN Books 
          ON Media.media_id = Books.media_id
          WHERE Media.media_id = $id");
   // echo"retreived Results";
    }catch(Exception $e){
        echo "Unable to retrieve results";

    $catalog = $results->fetch();
    return $catalog;
