Re: [PHP] Permissions set on php script question

If your web-server is setup to read files with .php extension   
through PHP engine (it is I guess)
than no body from outside (using HTTP)  can't read content of  
original PHP file only the output of that particular script.

The only concern you may have is that somebody else on that server  
can read that file.
Eg anybody who can login to server can read all your files with  
permission set to read on 'other'
