title: Wordpress, PHP, URL Encoding Issue
body: <p>Wordpress provides a function called "the_permalink()" that returns, you guessed it!, the permalink to a given post while in a loop of posts.</p>
  
  <p>I am trying to URL encode that permalink and when I execute this code:</p>
  
  <pre><code>&lt;?php
  print(the_permalink());
  $permalink = the_permalink();
  print($permalink);
  print(urlencode(the_permalink()));
  print(urlencode($permalink));
  $url = 'http://wpmu.local/graphjam/2008/11/06/test4/';
  print($url);
  print(urlencode($url));
  ?&gt;
  </code></pre>
  
  <p>it produces these results in HTML:</p>
  
  <pre><code>http://wpmu.local/graphjam/2008/11/06/test4/
  http://wpmu.local/graphjam/2008/11/06/test4/
  http://wpmu.local/graphjam/2008/11/06/test4/
  http://wpmu.local/graphjam/2008/11/06/test4/
  http%3A%2F%2Fwpmu.local%2Fgraphjam%2F2008%2F11%2F06%2Ftest4%2F
  </code></pre>
  
  <p>I would expect lines 2, 3 and 5 of the output to be URL encoded, but only line 5 is so.  Thoughts?</p>
