Archive Tar Bug?

I am encountering a problem using archive tar under Windows XP. I am calling listContent() to get the names of the files in a tar archive, but the function is failing due to a FALSE return code from _extractList. Modifying the code to return a TRUE status when _readHeader fails apparently makes the whole thing work - but I wonder if I am just masking another problem. My guess is that the _readHeader is failing because I am at the end of the archive - which is in effect a success condition. Here is the code snippet from _extractList: While (strlen($v_binary_data = $this->_readBlock()) != 0) { $v_extract_file = FALSE; $v_extraction_stopped = 0; if (!$this->_readHeader($v_binary_data, $v_header)) { return true; // return false; } if ($v_header['filename'] == '') continue; Any thoughts?
