Code to implement PHP array sorting_PHP tutorial

After a long period of development of PHP, many users know PHP very well. Here I will share my personal understanding of PHP array sorting and discuss it with everyone. PHP is a server-side scripting language that is easy to learn and use. With very little programming knowledge you can use PHP to build a truly interactive WEB site. This tutorial is not intended to give you a complete understanding of the language, but to get you started developing dynamic web sites as quickly as possible. I assume you have some basic knowledge of HTML (or an HTML editor) and some programming ideas.

PHP web page files are treated as ordinary HTML web page files and when editing, you can write PHP using the normal method of editing HTML. PHP stands for: Hypertext Preprocessor (PHP: Hypertext Preprocessor). PHP is completely free. You don’t need to spend money. You can download it freely from the PHP official site (http://www.php.net). PHP complies with the GNU Public License (GPL), under which many popular software such as Linux and Emacs were born. You have unlimited access to the source code and can even add the features you need. PHP can run on most Unix platforms, GUN/Linux and Microsoft Windows platforms. Having said so much, let’s explain about PHP array sorting.

PHP array sorting code:
