Block parsing of php in subfolder

Hello

I am hoping that this is the right place to ask this question, if not i
am sorry.

The title said it all, i want to block parsing in a subfolder ( and its
subs). I dont want to place a httacces fil in the folder.

The solution i have so far is a htaccess file in a padding folder above
the folder i want to block with this content:
<FilesMatch ".php$">
ForceType text/html
</FilesMatch>

This would have to be done with all extentions that are parsed.

This would work but php could be reactivated by putting an appropriate
htaccess file in the subfolder. And does not seem pretty.

Can this be done in a better way. Can complete phpblocking be done at
all?
