title: SSH2 for PHP7 MacOS?
body: <p>When trying to use </p>
  
  <pre><code>ssh2_sftp($this-&gt;con);
  </code></pre>
  
  <p>PHP 7.1.7 thinks Im looking for a function in the class. After some reading, I found that SSH2 needs to be installed from PECL 
  ( <a href="http://php.net/manual/en/wrappers.ssh2.php" rel="noreferrer">http://php.net/manual/en/wrappers.ssh2.php</a> ) </p>
  
  <p>When I went to do that, I got the following error:</p>
  
  <pre><code>pecl/ssh2 requires PHP (version &gt;= 4.0.0, version &lt;= 6.0.0), installed version is 7.1.7
  No valid packages found
  install failed
  </code></pre>
  
  <p>Anyone have any ideas on how to get this to run on MacOs 10.13.3 (17D47) with PHP 7.1.7?
  Thanks in advance!</p>
