title: Can I close a file by unsetting the handle?
body: <p>I'm a little puzzled if I can spare the <code>fclose</code> command by just unsetting the variable that carries the handle?</p>
  
  <pre><code>$handle = fopen($file);
  ...
  fclose($handle);
  
  ... // script goes on for a long
  </code></pre>
  
  <p>Compared with:</p>
  
  <pre><code>$handle = fopen($file);
  ...
  unset($handle);
  
  ... // script goes on for a long
  </code></pre>
  
  <p>Insights anyone?</p>
