file_get_contents with https?

I'm working on setting up credit card processing and needed to use a workaround for CURL, and the following code worked fine when I was using the test server (which wasn't calling an SSL URL), but now when I am testing it on the working server with https, it doesn't work ("failed to open stream").\[code\]function send($packet, $url) { $ctx = stream_context_create( array( 'http'=>array( 'header'=>"Content-type: application/x-www-form-urlencoded", 'method'=>'POST', 'content'=>$packet ) ) ); return file_get_contents($url, 0, $ctx);}\[/code\]
