What is PHP
PHP stands for PHP hypertext preprocessor programming language that is a web server-side that is open source. PHP is a script that integrates with HTML and are on the server (the server side HTML embedded scripting). PHP script is used to create dynamic web pages. Dynamic means that the page will display a page that is created when requested by the client. This mechanism causes the information received is always the latest client / up to date. All PHP scripts executed on the server where the script is executed

History of PHP
View from the development, programming language has a very rapid growth with the number of users who continue to grow.

1. PHP / FI
This is the embryo of the current PHP. First created by Rasmus Lerdorf in 1995, he was originally named this script "Personal Home Page Tools" which is a simple language from which the C programming language Personal Home Page This tool can communicate with the database and bersipat Open Source. Rasmus in the first programming language to create aims to keep the visitors who see the Bios on the web sitenya.
Perkembanganny, in mid 1997, the language PHP language more and more, seen from the number of statistical domains menggunkan PHP almost more than 50,000 web sites. Then, because the very rapid development, Rasmus develop this programming language, and in November 1997 appear PHP / FI version 2.0 which is the embryo of PHP 3

2. PHP Version 3
PHP Version 3 is a version of bugs penyempurna-bugs in the PHP / FI version 1.0 and PHP / FI version 2.0. PHP Version 3 is developed by Andi Gutmans and Zeev Suraski in 1997 that successfully written perfectly at that time. Additional Features PHP Version 3 compared to previous versions, in addition to extra-fumgsi new functions, also supports multiple access to many databases, protokool management, and API. From version 3 is the abbreviation of PHP appear, that is PHP: hypertext preprocessor, and in 1998 almost 10% web site in the world to use PHP as a web server.

3. PHP Version 4
In the winter of 1998, re-write the programming language PHP to make this programming language Reliability. Finally, in mid-1999 diperkenalkanlah PHP 4.0 version of the script using the Zend engine to improve the appearance (performance) and have very much support the extension of the library and its various modules. PHP version 4.0 also has advantages compared to previous versions, including support to several web servers, facilities HTTP session, the output buffer and system security. In the development, at that time was almost 20% the web server using PHP programming language as interpreternya.

4. PHP version 5
In July 2005, showing the 5.0 version of PHP using Zend Engine 2.0 with the addition of some featur and some new objects. For information featur-featur new version of PHP 5.0, you can see in http://www.zend.com/zend/future.php. PHP version 5 is strongly support-based programming, Object Oriented Programming aka oop and emang the allotment for the oop.

We often hear the term Hacker and cracker. However, some of us that many did not know about the understanding of what the two terms. And here, I will tell what the Hacker and cracker. Let's browse more yup ...

1. History Hacker and cracker

Hacker appear in the early 1960s among the members of the student organization's Tech Model Railroad Club in artificial Intelligence Laboratory Massachusetts Institute of Technology (MIT). The student group is one of the pioneering development of computer technology and they operate with a number of Mainframe computers. The word hacker first appears with a positive meaning to mention a member who has expertise in the field of computers and able to create a computer program that is better than that has been designed together. Then in 1983, growing hacker analogy to mention someone who has a obsession to understand and control computer system. Section, in the year for the first time the FBI catch the computer criminals 414s based in Milwaukee USA. 414 is the code of their local area. Group, which was then called hacker is declared guilty piercing top 60 computer, the computer's property Cancer Center Memorial Sloan-Kettering to a computer owned by Los Alamos National Laboratory. One of the perpetrators are getting TESTIMONIALS immunity because, while the other 5 to get the punishment trial.

Then in the next show other groups that breathe themselves hackers, but is not. They (especially adult men) who get satisfaction through the computer and break outmanoeuvre phone (phreaking). Hacker sejati call these people 'cracker' and do not like to interact with them. Hacker cracker sejati looked as lazy people, not
responsible, and not too smart. Hacker sejati not agree if it is said that someone with a security breach has been a hacker.

The hackers meet once each year that is held every mid-July in Las Vegas. Ajang meeting hacker in the world is called Def Con. Def Con event to event is more exchange of information and technology related to hacking activities.

2. The Hacker and cracker

1. Hacker

The term Hacker Taking on someone who has a big interest to learn the computer system in detail and how to improve kapabilitasnya. The amount of interest owned by a hacker may have encouraged untik control over the system that most average users. So, hackers actually have a neutral connotation.

Community in general, the term hacker is much tersalahgunakan or rancu with the term cracker. Especially when the discussion turned to crime. Where is the term for criminals that they actually mean is cracker.

In the underground world of a hacker is usually through the following stages:
1. Mundane Person
2. Picassoseven
3. Wannabe
4. Larva
5. Hacker

There are two levels of expertise based on the hacker, including:
1. Wizard
2. Teacher

Hacker character itself is divided into two, they are more inclined to the nature of the cracker. Both characters are:
1. Dark-side Hacker
2. Malicious Hacker

The stages by which they are to become a hacker. Actually difficult to say levels of the final end or hacker has been reached, because of course there is always something new to learn or found (gather information carefully and learn the basics of the same for a hacker) and it also depends on a feeling (feeling) . However, being a hacker is more menjurus thoughts on the matter.

2. Cracker

The term cracker free translations: Pembobol. People able to penetrate the code and key code (password) and the security system without the permission or not ethical. (Cracker) term was found by gadfly computer system to distinguish the use of computer aktivititas who violate the rules or to give the term a more activity based. This term also distinguish) (hacker as someone who advanced in the use of computer and its commands basically.

1. Passion, learning and practice

The first thing that is very important to me is a passion, interest, love. Just like other areas, control areas of IT must be accompanied with the desire that menggebu-gebu. Why would you want to menekuni this field?

IT does not control the field occurs in a flash time. He can not only created a seminar with the course. I see many people / students who come to the seminar and hope to become a champion. This is the same as we watch the game of soccer and then returned home hoping to become a champion direct football. Can not! To become a real expert take yearly, unless you just want to be a "specialist" (or often called celebrities IT).

Learn and practice is a method that I do. Study here, including reading books, magazines and other sources of reference (if the Internet is now). If necessary, review the background theory. Practice trying to apply what you read to improve their skills (skill) and enrich the "library" you are the solution.

For reading matter, including that I maniak. All I read. I read the fun things associated with computers began when I used to buy the magazine near the river Cikapundung (Bandung). Era that many foreign magazines that does not appear to be returned to the publisher but will be sold with a cover digunting. So, I started the magazine with the former! That is why I often wonder and annoyed with students who complain that he does not have the money to learn computers. If multiple books are now speaking of a computer affordable. If it is, I have to buy foreign magazines.

For a matter of practice, which many complain do not have the money to buy a computer. Who ordered to buy a computer? To practice your computer does not need to have your own computer. There are many places to learn the computer, such as a lab on campus, and cafe. You can work there while studying. If you need to work without pay. When I learn UNIX (on Sun machines), I help admin in campus lab. I took the computer out the cable, settle other issues in voluntir for 1 year. Just after that I was trusted to manage one of the computers there, and eventually the entire network.

2. Formal education, training, or learn yourself?

There are those who give the example that the formal education in the IT world is not necessary because it can dipelajar own. Then they give examples of IT whiz around them who have no formal education in the field of IT. Bill Gates drop out of Harvard. Steve Jobs did not finish college. Many other examples. But, whether true that formal education is not needed? People forget that Bill Gates for a successful, there may be 10 thousand dropout who failed. Of course the news about the dropout who failed not so interesting to be told it can be considered natural. It will be strange if the success of dropout is considered normal. I still include the thought that formal education is needed because the foundation to give him, even though it is not a guarantee of success.

So what about the people that are not formally educated? They may be successful, the origin would try harder. One path that can be implemented is with the training, even training in some places even have a value (value) is higher than usual in formal education. This is proven with more diakuinya certificate vendor (which notabene related to training, not with formal education) compared with ijasah universities.



I may include the categories through their own learning path. I do not have a certificate, but even issued a certificate. (See BRcertified.com.) Does Bill Gates have a certificate from Microsoft?) Formal IT education is very minimal because I when I study more science elektronikanya. If the electronics can be considered as IT, then I have a formal IT education. Of course education electronics background I was very helpful in understanding IT. However, if the order-sorted, my formal education programming is just programming in FORTRAN language. The control of other programming languages (perl, C, C + +, Java, and many others) comes from learning itself.

In trying to learn my own search (book) the best reference, reference that is used by the other gamecock. (This approach may not necessarily suitable for you, but this is the "flow" or "madzhab" I choose.) How is the search for information in mailing lists, web sites, and to help other people. Sometimes this reference book is difficult to understand, but the long run I better understand why a reference is used. So I do not find the book "xyz for dummies" book or the translation is even confusing. If you want to act, find the best teacher. Do not search the usual teacher-usual course.

Examples of books I use when studying for example:

* Book "camel" (O'Reilly edition) I use to learn languages perl. I choose this book because Larry Wall to write this book and the chance he is the author of the language perl. Lagian, then this is the only book that is perl. hi hi hi.
* Book "dragon" (essay Aho and his friends) to learn the compiler.
* Book-length Lippman (C + + Primer) when learning C + +. (This does not have the name of animals. Ha ha ha.)

Excess use of books with the same book used by experts abroad is nyambung if we can discuss. So there is no difference between them and me.

Note the name of the book. Usually given a nickname based on the book cover images (cover) from the book. For example the book "camel" has a cover image onta.

3. Programming language should I kuasai?

Always appear every time programming languages (and methodology) are new. At the time I learn programming, FORTRAN language and the flow chart is required by a programmer in mind. If the current language may be Java or C / C + + is more searchable. Similarly, the methodology that uses extreme or agile programming may be in increased leaf. For the development of web-based, PHP and ASP languages that are currently popular. (I prefer to use their own language perl.)

So what? Do you need to know a new language? The answer is no. Only the "insanity" is doing just that. (In this case I may be among the "mad" because I am happy to try a language-a new language.) This is the most important basics of programming. Language only "means of communication." If you take C, for example, it is not too difficult to master another language (the same or similar filosofinya). However, if you do not have basic programming, it will be difficult to develop for. For example, I take language perl. Appear when the PHP language with the easy bit because I understand the principle, not much different with the perl language.

4. Conclusion

This paper attempts to answer one frequently asked questions by many people (students, the training / seminars, mass media). Hopefully this short article that can answer some questions you may have.

Each active internet users around the world
certainly understand correctly, that the cyber world (online) is a world in which
all visitors are from the real world (offline). However, although
Therefore cyber world is not the same as the real world. Cyber world
the world is different, unique and interesting place to be. Either
two examples of the differences of this world, namely in terms of communicating
directly with each other. Opponent in the offline world we attend the talk
manifest before us, while in the online world, we do not talk opponent
kasat even have eyes. To bring the talk to her opponent
before us in virtual worlds is our own imagination. The
equipment such as pic chat, avatars, cam, and voice, is just
power tool to help us in the working brain berimajinasi at the time
that. Unique is not it?


Uniqueness of other, more cyber world offers
things that are privacy. Must write down the username and
password must first register for each event in each
server that provides the facility to chat, e-mail, and
website, one of the proof of protection against privacy servers
users.
Chat in the world, for example, servers that are
we use is very or extremely protect protect its customers.
For example, when other people will add to or take ID
(nickname) to us is stored in the messenger list it, there is a quote
first from the server related to us as a friend to chat people
, and agree whether or not ID our add-in by the man? When
agree, we live to click the box labeled allow, if not
just click the box labeled block / reject / deny. When the chance we
when using a webcam chat, also can not be any person
can be opened (to accept) we cam. Process the same request ijinnya
like when someone you want to add a list of others in the ID to its list.
Another example, when we do not want to be online by the
that have been terlanjur to add our ID, easy course, use the technique
invisible, so all our cyber friends think we're off.
Then we choose to live, where the ID that we want to do. One
example again, if we feel disturbed by one of his attitude friend
we have a virtual terlanjur often use to chat with us
PM (private message), the technique can be set disiasati presence
offline, so that the friend thought it frustrating that we are not
online aliases are off on our individual online. Had friends
chat is frustrating that we have been very comfortable with the
we socialize in the cyber, too easy to complete,
"Tendang" only he's our list. But when he was already IN the tedaftar
our messenger list, first delete its ID, and do not linger
ignore-it or blocking its ID.

But do not terlena with
facilities that function to protect internet users,
circumspection and vigilance still needed a Netter. And when
we experience things that are not desired, for example, our password
known people, or without us realize there are people who already know
many things about our private, that's not all one opponent to speak
us, also not a computer let alone a server. All the resultant
by our own carelessness, which is perhaps less at a time
response on the situation and the environment that we're enter
at the time, so that we unconsciously dijebak people to
broaden our privacy.

So essentially berhati2lah with whom we deal with someone in the cyber world. what u see is not always what u get.
