When $certificateAuthority is False,
the documentation for setSslVerification() in the Interface, at:
https://github.com/guzzle/guzzle/blob/master/src/Guzzle/Http/ClientInterface.php
says:
"Setting $certificateAuthority to FALSE will turn off peer verification, unset the bundled cacert.pem, and disable host verification."

This allows to have:
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0); 
which can be good for testing or troubleshooting. See this, work example.
