Get the full URL of your page using PHP
Very often we need to have the ful URL of the page and use it somehow in our code, for example a dynamic script with social bookmarks or anything else we can think of.

How to restrict visitor access to your web site
This tutorial by telling you that it's wrong to restrict access to your visitors.

PHP captcha verification
This way of preventing automated submissions is very used on the internet. More and more website owners start looking for a tool to prevent SPAM.I too have to delete about 200 SPAM messages a week submited through the comments area in this articles.

Create social bookmarks
Social bookmarks is a thing you must have on your website if you want to increase the number of your returning visitors. More and more people rely on sites like del.icio.us or ma.gnolia.com to store their bookmarks. I use it too. It's safer this way. Why should I store my valuable bookmarks on my hard disk when I change my system at almost every 2 months due to viruses, errors or who knows what other reason. I always lose something.

The "tag cloud" or "weighted words list" is nothing more than another way of displaying a navigation. It's funny, weird, new to the internet, attracts clicks, easy to do and it's also free.
