This class uses environment variables and date/time functions to log visitors data.
It has a constructor that initializes the objects using three input parameters. These input parameters are class properties.
These parameters are as follows:
1-$folder is the name of the folder the logging data are going to be saved in.
2-$logname is the name of .txt file that is going to be generated
3-$xmlname is the name of .xml file that is going to be generated
This class also has three methods. The first method is create_txt() which creates a text file containing visitor data.
The next method is create_xml() which acts like create_txt() method but generates an xml file and the final method is show_links.
The last method can be used to show the links to the log files on the browser.
