How to get file_get_contents() to work with HTTPS?

Question

I'm working on setting up credit card processing and needed to use a workaround for CURL. 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's failing with the error message "failed to open stream".

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);
}

To allow https wrapper:

• the php_openssl extension must exist and be enabled
• allow_url_fopen must be set to on

In the php.ini file you should add this lines if not exists:

extension=php_openssl.dll

allow_url_fopen = On
