throw new ArchiveCorruptedException('Header does not match it\'s checksum');

1. $header = @unpack(
2. "a100filename/a8perm/a8uid/a8gid/a12size/a12mtime/a8checksum/a1typeflag/a100link/a6magic/a2version/a32uname/a32gname/a8devmajor/a8devminor/a155prefix",
3. $block
4. );
5. if (!$header) { # throw new ArchiveCorruptedException('Failed to parse header'); # }
7. $return['checksum'] = OctDec(trim($header['checksum']));
8. if ($return['checksum'] != $chks) { # throw new ArchiveCorruptedException('Header does not match it\'s checksum'); # }
10. $return['filename'] = trim($header['filename']);
