Note Submitter: dwalton at acm dot org Reason: non-english ---- Another special (and underdocumented) variable in PHP is $http_response_header. This variable is automatically filled with an array of headers when you use file_get_contents() and similar functions to open a URL. 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.
