function file_get_contents_ssl($url) {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  curl_setopt($ch, CURLOPT_HEADER, false);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_REFERER, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 3000); // 3 sec.
  curl_setopt($ch, CURLOPT_TIMEOUT, 10000); // 10 sec.

}

For my use, I had to strip /blog from the SVG URL.
file_get_contents_ssl( str_replace('/blog', '', get_site_url()) . $menu_icon )
