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.
