I thought to use fileinfo to check if a file was gzip or bzip2. However, the mime type of a
compressed file is "data" because compression is an encoding rather than a type.
gzip files begin with binary 1f8b.
bzip2 files begin with magic bytes 'B' 'Z' 'h'.
e.g.
$s = file_get_contents("somefilepath");
if ( bin2hex(substr($s,0,2)) == '1f8b' ) { could be a gzip file }
if( substr($s,0,3) == 'BZh' ){ could be a bzip2 file }
I am not an encoding expert. My only testing was using a few of my own encoded files.
