A video encoder I need to query from PHP for status and settings provides a SOAP interface.

The vendor provides a WSDL file which includes 15 schemas with schemaLocation naming external URLs. The XSD files are also provided by the vendor.

Since the system must operate without a public internet connection, I modified all of the imports to point to a local url, eg

http://localhost/path_to_schemas/xml.xsd
http://localhost/path_to_schemas/settings.xsd
http://localhost/path_to_schemas/inputs.xsd

and so forth

How do I use PHP SoapClient to query the encoder(s) using the local WSDL and schemas? Can't find any hints in the PHP documentation or elsewhere online. Most examples assume the WSDL file will be on the queried device, which in this case its not.

So I tried specifying the WSDL as localhost and put the target machine and namespace in the options:

$options = array("location" => "192.168.2.161", "uri" => "http://www.appeartv.com/automation/v1");

$sp = new SoapClient("http://localhost/visor/options/optAppearControl/webgui/be/atvSoapSchema/ATV.wsdl", $options);
$result = $sp->getModuleList();

However, this fails with an exception "Unable to parse URL" on the getModuleList() line.

Apache error_log:

[Sat Nov 10 06:55:05 2018] [error] [client 192.168.2.10] 
PHP Fatal error: Uncaught SoapFault exception: [HTTP] Unable to parse URL

#2 /usr/local/webgui/be/testSoap.php(16): SoapClient->getModuleList()

Which URL can it not parse?

The PHP docs say that:

location is the URL of the SOAP server to send the request to, and uri
is the target namespace of the SOAP service

I'm a bit confused on what uri should be set to. The "target namespace" in the xsd and wsdl files shows:

<?xml version="1.0" encoding="UTF-8"?>
<definitions 
 xmlns="http://schemas.xmlsoap.org/wsdl/" 
 xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" 
 xmlns:tns="http://www.appeartv.com/automation/v1/wsdl" 
 xmlns:atv="http://www.appeartv.com/automation/v1" 
 name="AppearTV_Automation" 
 targetNamespace="http://www.appeartv.com/automation/v1/wsdl">
 <types>
 <schema xmlns="http://www.w3.org/2001/XMLSchema">
 <import namespace="http://www.appeartv.com/automation/v1" 
 schemaLocation="http://localhost/visor/options/optAppearControl/webgui/be/atvSoapSchema/automationInterface.xsd" />
 </schema>
 </types>

 <!-- system.xsd -->
 <message name="getModuleList">
 <part name="foo" element="atv:getModuleList"/>
 </message>
 and so on...

So is the target namespace atv (as used throughout the xsd files) or http://www.appeartv.com/automation/v1/wsdl (as shown in the wsdl file) or http://www.appeartv.com/automation/v1 (as shown in the xsd files) ??

I've tried all, but all show the same error message.
