Systems is what I call the scripts that make this site dynamic. For instance that it maintains the number of hits and visits, and also downloads. And also the stylesheets that are used randomly, which can be seen as you browse my site. The main advantage of this approach is that it keeps your code clean, easy to oversee and managae. All are free for download too, and also copyright free since I wrote them myself with some help of friends every now and then, here and there. SetStyle [Display random stylesheets] TotalHits [Count the total number of downloads for every file available] TotalDownloads [Same as above only with other files] Download Counter [Add 1 for every time that specific file is downloaded and display it] DisplayCopyright [Well since I found it easier to have as much php code as possible externally I wrote this one:)] AddBlackList [Not used, for adding IP that try to spam the contact form:) ShowModDate [To show the date a page was last modified] CaptchaCode [To secure your forms from spam and abuse] BlockWords [To check the input from any field before the mail is sent, also for security and anything you wish] ChangeLang [To change the overal language of your entire site, according to the HTTP_ACCEPT_LANGUAGE sent bythe visitor's browser] Many many more which are not yet to my liking but already function as expected... If you are interested in them email me via the above link or the contact page pls thanks.
