title: Class 'Net_SSH2' not found in... when using phpseclib
body: <p>I'm trying to use phpseclib to run a few ssh commands on my server. Attempting the below, I get <code>Class 'Net_SSH2' not found in....</code> which seems to indicate <code>phpseclib</code> is not properly loaded, yet the echo shows that the include is working.</p>
  
  <p>What have I done wrong here?</p>
  
  <h3>My <code>php</code></h3>
  
  <pre><code>&lt;?php
  ini_set('display_errors',1);
  ini_set('display_startup_errors',1);
  error_reporting(-1);
  
  $thepath = $_SERVER['DOCUMENT_ROOT']. '/inc/phpseclib/Net/SSH2.php';
  echo '&lt;strong&gt;Full include path:&lt;/strong&gt; '. $thepath;
  include ($thepath); 
  
  
  $included_files = get_included_files();
  
  foreach ($included_files as $filename) {
       echo "&lt;br&gt;&lt;strong&gt;Included file:&lt;/strong&gt;$filename";
  }
  
  
  $ssh = new Net_SSH2('xx.xx.x.xx.x'); // server's ip address
  if (!$ssh-&gt;login('username', 'password')) { // filled in correctly 
      exit('Login Failed');
  }
  
  echo $ssh-&gt;exec('pwd');
  echo $ssh-&gt;exec('ls -la');
  ?&gt;
  Done.
