I 0 basic want to learn to write a simplest PHP program Hello World but do not know how to download and install from the Internet and write it?

First learn the basics of PHP, and then go to Baidu to check the function of their own principles, and then to experiment, the success of the experiment on the site to use it.
After these four steps, you have learned a function of this technology.
Learn not PHP Most people have been repeating the first step!

W3school on the tutorial is very basic, very easy to understand, it is recommended to read it first. Then you can look at php100 video tutorial, this is very detailed and easy to understand, and speak a lot of knowledge, I also see this learned.
Or that sentence, see the tutorial is only in the back multiplication formula, only multiplication formula students will never do the application problem, only use it, that is the real learning!

I 0 basic want to learn to write a simplest PHP program Hello World but do not know how to download and install from the Internet and write it out

The simplest program is this:
Echo ' Hello, world! ';
?>

Download PHP can be downloaded in www.php.net, choose the binary code under Windows, you can download the installation package and zip package, I like the zip package, easily unzip to a folder, such as C:\php\ under. Double click on the saved (I use Notepad to edit) PHP file, choose and you just untie the C:\php\php.exe association on it.
