title: PHP can't setcookie()
body: <p>I'm having trouble expiring a cookie in php.  here's my code:</p>
  
  <pre><code>&lt;?php
  setcookie('reitinvestor_user', 'null', time()-3600,'',$_SERVER['SERVER_NAME']);
  setcookie('reitinvestor_pass', 'null', time()-3600,'',$_SERVER['SERVER_NAME']);
  echo '&lt;pre&gt;'; print_r($_COOKIE); echo '&lt;/pre&gt;';
  exit;
  ?&gt;
  </code></pre>
  
  <p>Everytime i hit refresh, I get this result:</p>
  
  <pre><code>Array
  (
      [_csuid] =&gt; 47dae7b6cd2d9e89
      [reitinvestor_user] =&gt; john
      [reitinvestor_pass] =&gt; 1f3870be274f6c49b3e31a0c6728957f
      [PHPSESSID] =&gt; 6027e370abad115e35b54b0be76befc8
  )
  </code></pre>
  
  <p>I can do a setcookie with different key values and also expire them.  I just can't seem to do it for reitinvestor_user and reitinvestor_pass.  What's wrong?</p>
