How to create file download counter?

问题

Which is the most simple way to create code ( with PHP and SQL ) which will count the file downloads ?

I already have an integer column in the base dedicated for this feature...

( link to some example will also be welcomed )

回答1:

Create an sql table with two columns:

1. Full path to file (primary key)
2. Counter

Setup your links for downloading to go to a php script. In that script, lookup the appropriate table row based on the full path, increment it's count, then redirect the browser to the file for downloading.

You can make a download script, which is very bad for performance. My solution would be just periodical apache access log parsing.
