Alternate to PHP exec() function

Question

Currently I am using:

exec("zcat $filename", $output)

To uncompress a .Z type file but unfortunately my hosting company has now disabled this function.

Is there a workaround?

$pathtofile = "filename.lis.Z";
exec("zcat $pathtofile", $output);

.Z files are LZW compression. If you can't run shell commands on your host, you can use an LZW PHP library. Here are two:
