title: Getting the names of all files in a directory with PHP
body: <p>For some reason, I keep getting a '1' for the file names with this code:</p>
  
  <pre><code>if (is_dir($log_directory))
  {
      if ($handle = opendir($log_directory))
      {
          while($file = readdir($handle) !== FALSE)
          {
              $results_array[] = $file;
          }
          closedir($handle);
      }
  }
  </code></pre>
  
  <p>When I echo each element in $results_array, I get a bunch of '1's, not the name of the file.  How do I get the name of the files?</p>
