Hello,

I would like to know more information about this. Specifically,

- what will be a good book on php which will help me understand these
topics and write codes?

- where can I find a sample code for these specific tasks I mentioned
below?

Thank you,

I know how to count an access to an index.html file, but I would like
to know:

1. I would like to know how to count the number of times a link is
clicked. A link is to a pdf file.

Easy way is to use a server side script language, best option would be
PHP as
you won't get limited to one operatingsystem.

Instead of calling directly the file you want people to download, you
make a
"wrapper" script, that keeps the count (save result to a file or to a
sql
server, mysql is a popular choice), and then feeds the user with the
file. Not
really that advanced to make.

This works kind of the same as the previous one, you have to include a
index.php file into the directory, the php script will list the files
in the
directory, as it lists the files it will also store the number of
times the
directory has been accessed to that file or database.
This too is quite easy to do.
