Question

How can I force my PHP SoapServer to send a JSON object as a response instead of an XML doc?

Thanks.

That is not SOAP, so no. It can incorporate a jsonstring in some xml node, that’s about it. You may want just a REST server serving json.

You can bastardize it though, making it by definition NOT SOAP, but some weird hybrid:

<?php
class ThisIsNotASoapServer extends SoapServer {

}
function test(){
        //should have a return
        //return range(1,9);
        //but totally breaks it by:
        echo json_encode(range(1,9));
        //the exit here is needed
        exit;
}
$server = new ThisIsNotASoapServer(null, array('uri' => 'http://test-uri/','soap_version' => 1));
$server->addFunction("test");
$server->handle('<?xml version="1.0"?>
<SOAP-ENV:Envelope
   xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
   SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
    <SOAP-ENV:Body>
        <m:Test xmlns:m="Some-URI"/>
    </SOAP-ENV:Body>
 </SOAP-ENV:Envelope>');
?>

… so, technically this is possible, but I suspect there is not a single client which understands this.
