SOAP: Invalid HTTPS client certificate path
===

When I run the below-given code, the error `ERROR: Invalid HTTPS client certificate path` is generated. I checked that the path to certificate.pem and test.wsdl is correct. What might be the reason of such error?

	$wsdl = 'http://localhost:10088/test/test.wsdl';

	$options = array(
		'local_cert' => 'http://localhost:10088/test/certificate.pem',
		'soap_version' => SOAP_1_1
	);
	

	try {
		$client = new Zend_Soap_Client($wsdl, $options);
		$result = $client->getLastResponse();
		print_r($result);
	} catch (SoapFault $s) {
		die('ERROR: [' . $s->faultcode . '] ' . $s->faultstring);
	} catch (Exception $e) {
		die('ERROR: ' . $e->getMessage());
	}
