I am working on my REST client library for CodeIgniter and I am struggling to work out how to send PUT and DELETE arguments in PHP.

In a few places I have seen people using the options:

$this->option(CURLOPT_PUT, TRUE);
$this->option(CURLOPT_POSTFIELDS, $params);

Annoyingly, this seems to do nothing. Is this the correct way to set PUT parameters?

If so, how do I set DELETE parameters?

$this->option() is part of my library, it simply builds up an array of CURLOPT_XX constants and sends them to curl_setopt_array() when the built up cURL request is executed.

I am attempting to read PUT and DELETE parameters using the following code:

        case 'put':
            // Set up out PUT variables
            parse_str(file_get_contents('php://input'), $this->_put_args);
        break;

        case 'delete':
            // Set up out PUT variables
            parse_str(file_get_contents('php://input'), $this->_delete_args);
        break;

There are two options here, I am approaching this in the wrong way or there is a bug somewhere in my libraries. If you could let me know if this should theoretically work I can just hammer away on debug until I solve it.

I dont want to waste any more time on an approach that is fundamentally wrong.
