using curl in php to publish data with faye

According to the author of faye i can send messages from any platform
and the format to post a message with curl is:

curl -X POST http://192.168.1.101:8000/faye -H 'Content-Type:
    application/json' -d '{"channel":"/foo","data":{"hello":"world"}}'

I format the previous line to be used in php

$data = array("channel" => "/one", "result" => "Hello World from PHP!!");  
$data_string=json_encode($data);
$ch = curl_init('http://192.168.1.101:8000/faye');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,"POST");
curl_setopt($ch,CURLOPT_POSTFIELDS,$data_string);                                                          
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);                                                              
curl_setopt($ch,CURLOPT_HTTPHEADER,array(
'Content-Type:application/json','Content-Length:'strlen($data_string)));
$result = curl_exec($ch);

Somehow the subscriber to channel one DOES not GET the result

the publish function in java script works seamlessly (see line below)

var publication = client.publish('/one',{ result: 'Hello World from JS'});<br/>

Please let me know what is missing or my mistake thanks
