HTTP Request file get contents not working

Question

I'm trying to send a file through rest using HTTP request to BonitaBPM but the file im trying to send comes out empty when i use file get contents and the HTTP request doesn't work obviously due to that

$file_contents = file_get_contents("C:/inetpub/wwwroot/upload/Director.png"); 
$data1 = array(
    "caseId"=> $case_id[1],
    "file"=>"C:/inetpub/wwwroot/upload/Director.png",
    "name"=>"doc_invoice",
    "fileName"=> $_FILES['file_attach']['name'],
    "description"=> "Invoice"
);
//Structure of process data to start case
$options1 = array(
    "http" => array(
        "method"  => "POST",
        "header"=>  "POST /bonita/API/bpm/caseDocument  HTTP/1.1\r\n".
            "Host: bonita.libertypr.com\r\n".
            "Cookie: ". $display[1]."\r\n".
            "Content-Type: application/json\r\n" .
            "Accept: application/json\r\n".
            "Cache-Control: no-cache\r\n".
            "Pragma: no-cache\r\n".
            "Connection: Keep-Alive\r\n\r\n",
        "content" => json_encode($data1)
    )
);
//decode process data and adds document to case
$url1 = "http://bonita.libertypr.com:8081/bonita/API/bpm/caseDocument";
$context1  = stream_context_create($options1);
$result1 = file_get_contents($url1, false, $context1);
$response1 =  json_decode($result1);

Please make sure that you are authenticated on the Bonita side before calling this API call. See this link for more details: http://documentation.bonitasoft.com/rest-api-overview#authentication

If you are not, the Bonita API calls will be rejected.

To analyze a bit further what is causing the issue, you should get your hands on the HTTP request and response sent between your code and Bonita. To do so, you can capture the HTTP traffic with a tool such as Wireshark
