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.

In Part 2 we'll look at the use of functions when developing web sites and applications.

A dedicated server is a type of web hosting system where the client leases a web server for themselves only, and no-one else shares it. Having a secure private network can give great peace of mind, particularly for firms who have sensitive personal and financial information concerning their clients.

This also means that you can be assured having full access to the data processing power and memory of the server whenever you may need it, as opposed to being at the mercy of other users on your server who may decide to take up a lot of power or memory just when you need it most.

Many suppliers of dedicated servers will let you have unlimited bandwidth, which means that you can have as much online traffic as you want to your dedicated server without being charged any extra fees. A major advantage of leasing dedicated servers is that you can always have the latest top of the range hardware for your business applications, just like when you lease a car and change it after three months to another newer model.

The suppler will have access to the latest technology and you will not be stuck with equipment that is getting more and more out of date. Similarly the dedicated server supplier will be able to save you money. For example they will be able to broker advantageous licensing deals for associated services like control panel access.

Another major advantage of dedicated servers is the ability to choose your operating system, for example Linux or Windows, so you can have the kind of operating system that fits the needs of your business. The ability to have full remote control of your dedicated server is an important requirement. This way, you can have access to the server control panel whenever you want, from anywhere in the world. You may need for example to re-boot your server, and with this capability you can do it yourself.

Effective technical support is vital if you have a dedicated server. You need to have access to experts whenever you need them, and the best dedicated server suppliers will be able to provide this kind of support twenty four hours a day, seven days a week. These experts will be able to manage and monitor your server, particular during times when there is a lot of online traffic.

The best dedicated server suppliers will have assembled a comprehensive online knowledge base, where you can read frequently asked questions. This is a great way to get a steer on what to do, especially at the beginning of a new arrangement. It is important to work with a dedicated server suppler who has a flexible back-up capability, which can be added to as your business grows, or you amalgamate with other companies.

Most suppliers of dedicated servers will have a number of packages that they can offer you. These will be typical arrangements of hardware and levels of management and monitoring that they find works well with other clients who are similar to you in size and business needs.

Making your web site easy for international visitors to understand is what website internationalization is all about. There are times when differences in vocabulary may crop up. This can even happen across different industries in the same country.

One of the ways you can help your readers is to start a Glossary.

In your glossary you can list industry specific words and all words you use commonly where others may not have the exact same understanding. If you explain a process in your communication, think of including verbs in your glossary.

The key to making your glossary work for you is to strive for accuracy, clarity, and ease of understanding.

Accuracy

In some cases a lack of accuracy can have devastating effects.

• In health issues.
• In reference to using machinery.

Clarity

A glossary's aim is to give a clear meaning to the words you use. Keep your explanations as clear as possible. If they only lead to further misunderstandings or do not answer the readers questions, you would be better off without one.

Ease Of Understanding

Keep your glossary very easy read and people will enjoy reading it. Pay attention to the general appearance of the glossary as a whole as well as the individual explanations.

An Added Value

After ready through a well done glossary, the reader may well come away feeling appreciative of the easy to read informative experience. It is a wonderful touch of thoughtfulness to your international visitors.

Non-native English speakers will greatly appreciate its value.

Prepares For Translation

A glossary is highly recommended in certain industries where specific vocabulary requires expert translations.

In some instances some people feel they can take a dictionary out and provide translations of key vocabulary in languages other than their mother-tongue. This can lead to further misunderstandings. A glossary well done is far better than taking on translation skills when you do not have them.

However, your glossary will be of significant value to a professional translator once you decide to offer multilingual services.

Glossaries are also appreciated in non-technical areas too. Cultural habits differ. People can use vocabulary differently. Glossaries provide insight into how you communicate and provide a base for cross-cultural dialogue.
