If you use SSL with a cert and password authentication:
$wsdl = "https://ws.ecopatz.de/ProductInfo?wsdl";
$pass = 'a password';
$certFile = "./mycert.pem";
$client = new SoapClient($wsdl,
array(
'local_cert' => $certFile,
'passphrase' => $pass
)
);
If you have problems with the certfile like this:
Warning: SoapClient::__construct(): Unable to set local cert chain file `./mycert.pem'; Check that your cafile/capath settings include details of your certificate and its issuer in productinfo.php on line 27
then the certFile is probably in the "wrong format" (the wrong format for php maybe). It worked for me, when i appended the content of the private key file and the certificate file to a single file "mycert.pem":
cat mycert.key >mycert.pem # mycert.key was the private key
cat mycert.crt >>mycert.pem # mycert.crt was the signed certificate
Thanks to an author somewhere, who pointed to "curl --cert", where this little "so unimportant" dependency has been mentioned.
