Check if php-cgi server is connectable remotely
<p>I have a php server listening on a port that seems to have issues. How can I connect to the php-cgi server to find out it if it up or not? (Sort of "ping" the php-cgi process)</p>

<p>I need to determine if the issue I'm having is due to the http server or the php-cgi server. Therefor I want to be able to "ping" the php-cgi server to make sure it is accepting requests. If not, I know it is the php-cgi server that is the cause of the problem.</p>
