title: Make it doesn't returns only 1 value
body: <p>I'm doing a query with PHP to bring from the database only the value <code>user</code>, here's the function I'm using:</p>
  <pre><code>$sentence = $connection-&gt;prepare(&quot;
      SELECT DISTINCT user from users ORDER BY RAND()
  &quot;);
  $sentence-&gt;execute();
  return $sentence-&gt;fetch(PDO::FETCH_ASSOC);
  </code></pre>
  <p>The variable <code>$sentence</code> is being used to make the SQL query. Then we execute the query and use <code>PDO::FETCH_ASSOC</code> so the result is not repeated. When I show the result on the web, its only bringing 1 value, random but only one. How can I make so it brings the number I want of results?</p>
