PHP User Step Logs: Record the pages a user accesses in a database

This class can record the pages a user accesses in a database.

It can take the identifier of a the current user, probably already logged in or the respective session identifier, and stores a record in a database table along with other details of the current user access.

The class stores the current request page URI, the URL of the previous page from the referrer header when present, the request query string, request parameters for POST requests, and the current date and time.

An auxiliary class accesses the configured database using PDO.
