title: PHP fgetcsv() delimiter
body: <p>Regarding to <a href="http://php.net/manual/en/function.fgetcsv.php" rel="nofollow"><code>fgetcsv()</code></a> documentation, there are some parameteres inside <code>fgetcsv()</code> function:  Handle, length, delimiter, enclosure, and escape.</p>
  
  <p>Now, I have 2 questions:  </p>
  
  <ol>
  <li>What does enclosure do exactly?</li>
  <li>I have a csv file with 5 columns per line. Imagine it something like this: <em>1,2,3,4,5</em>  </li>
  </ol>
  
  <p>So indexes are from 0 to 4. But whenever I want to get date from index 4, an empty value returns. Unless I put a comma after it (by filling an extra column after it that makes the contents like this: <em>1,2,3,4,5,6</em> ). How can I solve this issue ? It seems that there is some problem because of missing comma after the last item in each row of csv file!</p>
