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.

Rack mount servers are essentially systems that are in a modern server and are used to mount different sizes and kinds of electronic modules. Rack mount servers would be ideal for individuals who need to set or probably pack a couple of personal computers to a smaller space.

This kind of server is commonly employed in many areas and countries globally for a lot of purposes and reasons. Rack mount servers are used wherever an application of computers has to be used for a wider and larger application, which could star t from video editing suites to computer animations to the other kinds of three-dimensional tasks.

These rack mount servers are also utilized for the installation of different Internet service providers or ISPs in the field of telecommunications as well as in the other types of communication and for different database houses. They are created and are designed to be able to fit in an open PC or probably in a closed cabinet. One advantage for the use and implementation of a rack mount server would be that they could really prove to be very functional and useful if someone needs or wants to save some space. The space-saving design of rack mount servers allows the user to maximize the space he or she has.

The role of these servers is crucial, as proper and adequate setting and support of hardware to a well-built storage space would ensure that they are would be well-protected from any external elements and other factors.

The thing about computer languages is that there is some weird heaviness on the actual work involved. People are scared of by codes and although they see the power, they just can't seem to get going because they have no idea where to start.

That is where training comes in. And of course, fun training. You need to be taken by hand and shown exactly what you need to do, where you need to do it, and when you need to take the right action.

The funny thing about CSS is that it allows you to create your website in the fraction of the time when you would do it using tables. It's hard to believe, but still after all these years of promotion for CSS people (and companies!) still heavily rely on tables for layout. They have no idea that they are simply wasting time on old techniques that will be useless in a matter of time.

So where do you need to pay attention on when you are looking for a CSS Guide?

1. The Teacher

The number one thing you need to be sure of is that your teacher knows where he or she is talking about. Why is he or she teaching about Cascading Stylesheet, because they need to from their boss? Because they think they can teach, no matter the subject?

Think of that, how many teachers are only "teaching" stuff, and never practice it their own? Ask yourself "why" are you teaching you me this. Are you the best in the field? Where did you get your knowledge from?

2. Teaching Style

So the teacher may be a great person, has all the required skills, has a passion for the subject and knows about everything of it. But can your teacher deliver? Does he or she KNOW how to explain things? How to take you by hand and show you step-by-step how things work?

Is it fun to follow along with the teacher? CSS is one of those topics that can become boring easily when it's only discussed in a technical way. Make sure you know what you can expect!

An even more important thing is cutting right to the case. You don't want to end up with all kind of knowledge that you will never use in practice. It simply isn't useful to learn every possible css style there is when you just get started. And this brings us to the third point you need to pay attention on when you are looking for a css guide.

3. Teaching / learning speed

Can you keep up with the course? Does your teacher decide the speed, or do you? Of course a great way to follow a course is one that allows you to define your own speed. Home study courses and guides are wonderful for that.

4. Delivery

How is your guide delivered? Are you somebody that likes to read, follow along with a training video or both? Decide what you like, training videos are great, because they allow you to follow along in a real life situation. This means hands on practice, which is exactly what you need if you want to become good in CSS.

5. Contents

Last but not least, content. What is discussed in the guide? What is marked as important? Do you get a total reference, or do you know you don't need that, that the real thing you need is a hands on course with day-to-day subjects? Decide what you want to know, just the basics, how to create full layouts, or just how to create a menu using 100% CSS.

It's up to you now, decide what you need, you know how important the 5 above points are, and where you need to pay attention on. And one last tip, make sure you get some preview videos or sample chapter before following any course, it can save you a lot of time and money at the same time.
