Question

I’m trying to send an request to an Self-Hosted WCF-Service with REST in PHP.
I want to send the object to the WCF service as an JSON Object.
I did not get it running yet.
Has anyone an example how to call the service out of PHP?

This is the Operation contract (The method is a POST method):

[OperationContract]
    [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
    void Method1(AnObject object);

The best working Code in PHP is the following:

$url = "http://localhost:8000/webservice/Method1?object=$object"; 
    $url1 = parse_url($url);

// extract host and path:
$host = $url1['host'];
$path = $url1['path'];
$port = $url1['port'];

// open a socket connection on port 80 - timeout: 30 sec
$fp = fsockopen($host, $port, $errno, $errstr, 30);

if($fp)
{
    // send the request headers:
    fputs($fp, "POST $path HTTP/1.1\r\n");
    fputs($fp, "Host: $host\r\n");

    fputs($fp, "Content-type: application/json \r\n");
    fputs($fp, "Content-length: ". strlen($object) ."\r\n");
    fputs($fp, "Connection: close\r\n\r\n");
    fputs($fp, $object);
//
//  $result = ''; 
//  while(!feof($fp)) {
//          // receive the results of the request
//          $result .= fgets($fp, 128);
//  }
}
else { 
    return array(
        'status' => 'err', 
        'error' => "$errstr ($errno)"
    );
}

// close the socket connection:
    fclose($fp);

But this code does not send the object. In Debugging-Mode the Object is “null”. I just see, that it enters the method.

I found the solution for my own problem:

$url = "http://localhost:1234/service/PostMethod"; 
$jsonObject = json_encode($transmitObject);

    $options = array(
    CURLOPT_HTTPHEADER => array(
        "Content-Type:application/json; charset=utf-8",
        "Content-Length:".strlen($jsonObject)));

    $defaults = array( 
        CURLOPT_POST => 1, 
        CURLOPT_HEADER => 0, 
        CURLOPT_URL => $url, 
        CURLOPT_FRESH_CONNECT => 1, 
        CURLOPT_RETURNTRANSFER => 1, 
        CURLOPT_FORBID_REUSE => 1, 
        CURLOPT_TIMEOUT => 4, 
        CURLOPT_POSTFIELDS => $jsonObject
    ); 

    $ch = curl_init(); 
    curl_setopt_array($ch, ($options + $defaults)); 
    curl_exec($ch);
    curl_close($ch);
