With billions upon billions of people on the Earth and an estimated fifty seven million square miles of land, who would have thought that it would be possible to interact with virtually every single person from the comfort of your home or office. No, I'm not talking about talking to them over the phone or writing to them by mail but being able to interact with them via the Internet. Now more than ever, more and more people own computers with Internet connections and are surfing the web.

With billions of Internet users jumping from site to site, there will be those that will stumble upon your website. The question is, do you know anything about those website visitors? Are you getting detailed reports about your web visitors? If not, then as a webmaster you need to seek out the proper website visitor tracking software.

One that will be able to tell you everything about your visitors, like what they're doing when they visit your site or how long they are staying on your website? What links are they clicking? All these questions and more need to be answered. So if you are going to use a visitor tracking software, you might as well use the best. Provided by the advertising behemoth Google incorporated, Google Analytics is just the tool to use.

Google is a multi-billion dollar company that has resources to craft an excellent website visitor tracking software for all webmaster everywhere. This versatile services has an array of features including fast implementation, geo-targeting, customizable dashboards and more. The best part about Google Analytics is that its free. Any and every webmaster can afford the service. So if you are looking for a website visitor tracking software, I highly recommend Google Analytics.

If you are wondering why it is important to keep track of your website visitors, here are few reasons why. First, if you know important information like what your top exit pages are, then you can optimize those pages to preserve your traffic. Secondly, if you have ads on your website, you can use the site overlay feature to see what links your visitors tend to click on the most and reposition those links and place ads there to increase your ad revenue exponentially.

You see, Google Analytics can provide you with tons of valuable information. Information which can increase the productivity and effectiveness of your website. But I must say that there may be some what of a learning curve to the service. You may need to visit the Google help center or watch high quality training videos from programs like GlyticVideos. Once you've gotten a great understanding of Google Analytics, then you can fully utilize and get the most out of the service.

Reusing pieces of HTML code is a common way of making web sites (or web applications) more consistent, reliable, and more manageable. Even a small web site consisting of perhaps 20 or 30 web pages can benefit from reusing code for header and footer sections, for example. If the same header or footer is used across all the pages on the site, it makes sense to put the header and footer code in separate files, and then call those files to insert their contents where required.

PHP offers two statements that can be used for inserted the contents of one file inside another: include() and require(). These two statements are virtually identical, with the only real difference being that if require() fails, it gives a fatal error, whereas if include() fails it just gives a warning. For this reason I tend to use the include() statement as it just seems slightly more friendly.

So, to include the contents of a file called header.inc inside a web page called index.php, you would just need to insert the following line of code (wrapped in PHP opening and closing tags) inside index.php.

Include 'header.inc';

As PHP takes no notice of the extension used for the included file, you can use whatever extension you want to. Be careful though, if you put passwords inside an include file with a .inc extension, they will be visible. You can get around this by putting include files that contain sensitive information outside the document tree to prevent people from browsing to them.
