Just download and install it and you can use it. There are many integrated development environments like this. If you have installed the PHP+Mysql development environment according to other books, you don’t need to change it after debugging. I rented the space, so it doesn’t matter if I debug it locally, the effect will be the same.
The coding software I use is dreamweaver. To be honest, I only use its code highlighting and CSS features, and write all the code by hand. You can use Notepad or Zend Studio (but don’t blame me if you encounter problems, because you can also watch my tutorials and write programs in LUNIX, or even study on a spaceship, as long as you don’t go against my writing this book Purpose. )
ftp upload tool can be used: FlashFXP, etc. These things are all available on the Script House website.
I use UTF-8 encoding for PHP files. The advantage is internationalization and good code coupling between functions, which has advantages over GB2312. If you want to use GB2312, that's fine, but you have to adapt some of the two or three functions in this book, involving files, databases, URLs, etc.
PHP’s head has this line:
You can use dreamweaver Menu: Modify--Page properties, change the page encoding to utf-8 (the default is this).
Hello world program is not provided in this book, so let’s use this example instead:
Hello world actually mainly uses PHP’s output content function.
echo "Hello world";
?>
Example 1: Output values from 1 to 100
