Note Submitter: dwalton at acm dot org ---- If you fetch a URL with file_get_contents() or related functions, the HTTP headers will be put into the magic (but sorely underdocumented) variable $http_response_header as an array. This is true even when the function fails due to a 4xx or 5xx error and returns false - the headers are still available in $http_response_header. And unlike stream_get_meta_data(), this is not limited to just those functions that operate on stream references.
