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);
do this
echo ini_get("disable_functions");

system();
exec();
passthru();
shell_exec();
but if it's a shared hosting all the above are for sure blocked and you will have to find an alternative
system($shell_command, $response_var);
So in your case:
system("zcat $filename", $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:
