If you’ve upgraded to Mavericks from an earlier version, and you’ve installed PHP extensions using MacPorts, read this article to upgrade PHP extensions for Mavericks server before continuing with this article.

Download and install MacPorts from http://macports.org.

The following steps are performed in the Terminal:

Force MacPorts to update:

sudo port -v selfupdate

Now, install ssh2:

sudo port install php54-ssh2

Next, you need to edit /etc/php.ini to add the extensions. Find the phrase Dynamic Extensions, and add:

extension=/opt/local/lib/php54/extensions/no-debug-non-zts-20100525/ssh2.so

And finally, restart Apache:

sudo apachectl restart

To confirm installation, create a new PHP document called phpinfo.php with the following contents:

<?php
 phpinfo();
?>

Point your browser to the URL of that file. If all went well, you’ll see this block:
