Printing out the result of an sql query not working : <p>I'm trying to execute a SQL query and print out the return on a webpage. It should print out a list of names from the table but it simply returns "NULL". Does anyone have an idea how to fix this?</p>

<pre><code>$sql = "SELECT name from Players_christmas where name not in (select name from Players_halloween");
$assoc = mysqli_fetch_assoc($sql);
var_dump($assoc);
</code></pre>
