Simple PHP Post Problem

PHP

Hello,

I am trying to use an API offered by a website in PHP however I am facing problems. I can use the API very fine in C#. The following code in C3 works:

string result = wb.UploadString(apiurl, "POST", "Hello, where do you live");
            MessageBox.Show(result);

The above code works perfectly find. But I want to make the same code in PHP. In PHP I am utilizing HTTP POST from PHP without CURL , I have tried with CURL as well but it just doesn't work, I do not get anything returned from the API.

The following is the PHP code:

function do_post_request($url, $data, $optional_headers = null)
{
    $params = array('http' => array('method' => 'POST','content' => $data));

    if ($optional_headers !== null) 
    {
        $params['http']['header'] = $optional_headers;
    }
    $ctx = stream_context_create($params);
    
    echo $ctx['content'];
                                                   
    $fp = @fopen($url, 'rb', false, $ctx);          
    
    if (!$fp) 
    {              
        throw new Exception("Problem with $url, $php_errormsg");
    }
         
    $response = @stream_get_contents($fp);          
    
    if ($response === false) 
    {
        throw new Exception("Problem reading data from $url, $php_errormsg");
    }  
    return $response;
}

$result = do_post_request($apiurl,$txtstr);
echo $result;

I get no result, Neither do I get any error.

The API has strict condition that:
you should put your content as the POST DATA, and don’t write any other content or parameters in the POST DATA

Any one have any idea and can help me?
