title: Mysqli fetch_assoc vs fetch_array
body: <p>When I'm returning one row from a table, to gather the results I usually use e.g.: </p>
  
  <pre><code>$info = $result-&gt;fetch_assoc(); 
  </code></pre>
  
  <p>What is the difference between that and:</p>
  
  <pre><code>$info = $result-&gt;fetch_array();
  </code></pre>
  
  <p>Is there a reason to use one over the other when returning only one row, or is it just personal preference?</p>
