SOAP-ERROR: Parsing WSDL: Couldn't load from <URL>

I solved this on my WAMP setup by enabling the php_openssl extension, since the URL I was loading from used https://.

I had exactly the same error message. In my case, making an entry in my /etc/hosts file (on the server hosting the service) for the target server referenced in the WSDL fixed it.

Kind of a strangely worded error message..

I had this problem and it took me hours to figure out. The mainly reason of this error is the SoapClient cannot stream the web service file from the host. I uncommented this line "extension=php_openssl.dll" in my php.ini file and it works.
