Hi, thanks for the suggestion but that does not answer the question.
If anything I would put the files outside of the public_html directory. What I'm asking for is on the or on first access writing a license no. to all php files.
Client A license no. = 10098
Client B license no. = 10112
In the source code for index.php and all other .php files in Client A download
