What Is PHP?

The full form of PHP is Hypertext PreProcessor and is a server-side scripting language. The PHP code can be combined with regular HTML tags and parsed on the server. The creator of PHP, Rasmus Lerdorf first displayed the language in the form of a Perl script . In 1997 it was adapted by Andi Gutmans and Zeev Suraski to use a C-written compiler. They completely reconstructed the original PHP into the web language that we know and use today.

Uses of PHP

It is used in the creation of dynamic web pages. Web developers like it because of its fast parsing and flexibility and versatility. PHP is a popular tool for managing a form's data after it is submitted and comes built in with many different interfaces and API's. It has database capability built into the language, the most common database being MySQL. Typically the PHP can connect to any SQL enabled database.

The Syntax of PHP is similar in structure to Perl and C where curly braces { } define blocks of code and semi-colons specify the end of a statement PHP is as easy to learn as Perl. It maintains all the traditional loops, if/else, and subroutines that are expected in a programming language. One difference between the two is that the code'?' is embedded in with the HTML; you could however, use a separate file. The PHP code is different from HTML code by use of the opening and closing tags. When it finds a PHP file, it tells the server to scan through for these tags, and execute the code in between them. The server recognizes a PHP enabled file by its extension, .php. These are essentially HTML files with PHP codes in them.

Getting Started

To start PHP requires a server with PHP installed and a simple ASCII text editor such as Notepad or VI, eMacs, Kate, etc. for a UNIX/Linux machine.

What are the problems faced by PHP?

It is case sensitive. For example if you name a variable $MyVar, you cannot call it as $myvar or $mYvAr. In case you forget to close your curly brackets, then it helps to indent lines inside the curly braces so that any missing braces can be spotted easily.

Before you actually begin your website you have to put a lot of consideration into things such as the domain name itself and the hosting company you sign up with. These decisions can have a major affect on the end result so ensure you do your research to get the best outcome.

Once you have found the desired domain name you have to get it registered, there are a number of companies that offer the registration of domains so how do you decide which to use? The first thing you should look for is their reputation, you would hate to deal with a dishonest company that doesn't offer the customer service you deserve. In order to find a reliable company you can ask for recommendations from friends and family or other webmasters to see who they use. The next factor you should look at is the price, don't be fooled for the cheapest companies out there. Just because they can offer a cheap service doesn't mean that it's the best choice, check for renewal prices and any other disadvantages you may be faced with so that you can be confident you are receiving the best deal.

When you have your domain name the next step is to choose hosting, you cannot afford to rush this decision as it will determine the results of your website. Put the time and effort in to check which hosts are reliable and offer great customer service. Never accept anything below 99.99% up time as you will be loosing money every time your website goes down. You then have to spend the time in order to get it back up and running as intended, loosing even more money. Browse through each of the different hosting companies, checking the additional features, benefits and mainly the price in order to get the best deal based on your requirements.

You can find various companies such as name cheap, triple and go daddy who can be the solution to all your problems. You can register your domains with them and buy hosting at the same time, this takes a lot of the hassle out of the equation as everything is in the one place. There are some advantages to doing this, you can often get a reduced price if you buy them both together. It will give you more time to focusing on your website and if you ever have a problem you only have to contact the one company. Ensure that you check out the hosting package before you buy it to make sure that it has the features you require.

With the benefits it does have it's disadvantages, depending on the company the hosting may not be the best option out there and you can often get various coupon codes to make things cheaper and by shopping around you can always save a great deal of money.

This is a question you will have to address. Many folks just a build a website but do not think out why they are really doing it. As a result they don't take it seriously and therefore they do not get serious results. This makes logical sense right?

A website in and of itself means nothing unless it has visitors and achieves a certain objective. So you have to be clear what you want to achieve as this will help you focus on your research and build a site that can achieve your objective. Quality research will help you build a quality website.

To build a business online you are going to have to build a relationship with your site visitors. You will need to show them how to connect the dots and you can only do this by providing valuable content that is benefit driven.

Furthermore you are going to have to show them solid evidence of how your product or service can help them achieve results. Connecting the dots means moving them closer to their outcome. Once they can follow this and see how it will work for them you will naturally build credibility which will result in you having a profitable website.

As mentioned when you build your site you want to clearly have your visitor's objectives in mind so that you can address their concerns and overcome their objections. If you can help them achieve their goals it will be a win win situation for all parties concerned.
