PHP scripts embedded into the HTML codes. When someone checks the source code of the page, he doesn't get anything about PHP scripts. He only learns the HTML part of coding. This article is an introduction to PHP scripting language. One can find useful information and have enough knowledge after reading my PHP tutorial series. Without delay, I would like to start my script creation step by step.

Before starting, you should know that you have to set up PHP installations into your computer. Such installations are PHP itself, Phpmyadmin interface, Mysql database and Apache Server. Without these, your scripts are nothing since they are not compiled by your computer.

Step 1:

To write PHP scripts, we need a place. That place is a simple text editor. You are free to choose your text editor. I prefer to use Notepad. There are other alternatives like Editplus or Elfima. If your operating system is not Windows but Linux, you can place your code into Vi editor or Pico. I have never tried but I think you can use Dreamveawer, Hotdog or Frontpage.

In your text editor, open an new file and save it as “myfirst.php” or “myfirst.html” . I choose the name of file as “myfirst” but you are free to choose anything.

Step 2:

I have told you before that PHP scripts are embedded into HTML codes. So, first of all we will write HTML codes. The basic codes are HTML, TITLE, HEAD and BODY. It can be written by lowercase letters as well. This part is not important.

Step 3: All PHP scripts start with “ ”. Only the part between two is compiled by server and evaluated as output.To print characters on the screen, standart output functions of PHP are used. Those are “ print ” and “ echo ”. In some circumstances, ” printf ” is used too.

The format of printing:

1. print ( “ your output ” ) ;
2. print “ your output ” ;
3. echo “ your output ” ;
4. echo ( “ your outpu t” ) ;

If you don't use any white space characters, the strings are written without any separation. For example if you write this code;

• Print ( “ Word1 ” ) ;
• Print ( “ Word2 ” ) ;

It will be outputted as Word1Word2.

To remove this fault,white space characters are used. In PHP code part, between print functions, we place < br > code.

Example: To be more understandable,I will write a simple PHP script. Output will be the name of my favorite Triond writers.

Since I have been familiar with Key Creator for 2 years, I have drawn many simple and complicated geometries. However, one of my friends claimed that I couldn't draw the solid form of an oblique cone. I stumped when I heard his challenge on my technical drawing capability. It was really difficult to solve such problem but I did. Now, listen and learn how to draw an oblique cone. There may be of course many ways of drawing an oblique cone but I claim that mine is the easiest.

Oblique cone is a cone whose apex are not aligned above the center of the base. First of all we'll determine the exact location of the point of apex. After that, we draw the base circle with its given dimensions. Most of the time we know the radius or the exact location of the center. Then we use the menu of solid drawings. Under create menu we see an option swept. Now push the swept and then loft button. We choose curve-edge option for circle and point option for the point from sub-menu. Then, Key creator applies your command automatically. Look. You draw an oblique cone. The final part is to make a layout for your solid drawing. To do this, press into layout button and choose create instance option. Now you can see the top, front, right and isometric views of your work on the screen. How simple how easy.

I wish life could be as easy as drawing an object.
