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.

The key to building any website is to build it with your visitor in mind. What can you truly do for them that will add value to their experience when visiting your site? Let's take for example that you enjoy building model planes. The first place you are going to visit is the online forums.

The reason I choose forums is because this is where conversations take place relative to any given topic. This will give you a measure of interest. The first step is to see how up to date the forum is and secondly how many posts it receives per day. Additionally how many people respond to those posts on any given day?

Obviously the more the better, the more interest the better for you. The next thing you are going to look for is, what are the questions being asked and can you engage in the conversation and offer solutions. If this is the case your next task is to look for keywords. What keywords do people use to seek out solutions for their needs?

The next thing to do is look for a keyword tool. I am going to use Google's keyword tool for this example. Keyword tools by the way are not by any standard of the imagination an exact science. They give you a rough guide as to how many times a given keyword is searched. So do not think that the numbers you get are exact.

Your task right now is to develop a list of keywords.

Once you have this list you are now going to look at the level of competition. Starting out we do not want too much competition but remember competition is good as it means there is money to be made in that market.

We at this point are just looking for cheaper ways to enter the market. To do this enter your keyword into the search box in quotes. Then check how many websites are coming up for that keyword. If it is in the millions that is not good if it is in the thousands then that is great.

You will now be refining your list based on competition. Once the list is completely refined you will now have the general structure of your site. These keywords will make up individual web pages.

To conclude this is how to lay the foundation then once you have these keywords you will be ready to structure each of the pages on your site using each individual keyword with content relative to that. To learn how to put all this together select any of the links provided.
