OK. Obviously this script doesn't do, what I would like, since it purged all my files. No harm done anyway, I did it on purpose on a testing website which was also spamed.
Before I ran the script, I also tested only with sed using this code:
Now, this sed command is the only command in this script which I don't know what exactly does it do. I looked a little through "man sed" but I didn't understand much. I now cmp compares the files, and if they are the same the file index.temp gets removed, if not, the file index.temp becomes index.php. right? What about sed?
I can say, that the above command of sed, just copies the file index.php to index.temp. Nothing else.

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
