I want to learn to write the simplest php program hello world, but I don't know how to download, install, and write it from the Internet?
First, I learned the basics of PHP, then I went to Baidu to check the functional principles I needed, and then I went to experiment. After the experiment was successful, I used it on my website.
After completing these four steps, you have learned a feature of this technology.
The vast majority of PHP students have been repeating the first step!

W3school tutorials are very basic and easy to understand. We recommend that you read them first. Then, let's take a look at the php100 video tutorial. This lecture is very detailed and easy to understand, and I have learned a lot about it.
In other words, the course is just a multiplication step. Only the students who use the multiplication step will never do practical questions. Only using it is the real learning!

I want to learn to write the simplest php program hello world, but I don't know how to download, install, and write it from the Internet.
The simplest program is like this:
<? Php
Echo 'hello, world! ';
?>

To download PHP, you can download it at www.php.net. To download the binary code under windows, you can download the installation package and ZIP package. I like the ZIP package. just decompress it to a folder, for example, c: \ php. Double-click the php file saved above (I used notepad to edit it) and select to associate it with the c: \ php \ php.exe file you just unlocked.
