This article mainly explains "what are php and python". Friends who are interested may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what php and python are.

Php, which means "hypertext preprocessor" in Chinese, is a free, open source, cross-platform, server-side scripting language that can be used to develop website daemons. Python is an interpretive, object-oriented, dynamic data type high-level programming language. The source code of Python follows the GPL protocol.

What does php mean?

PHP (PHP: Hypertext Preprocessor), or "hypertext preprocessor", is a free, open source, cross-platform, server-side scripting language used to develop website daemons.

PHP is especially suitable for Web development and can be embedded in HTML. PHP grammar learned C language, absorbed the characteristics of Java and Perl to develop its own characteristic grammar, and continuously improved itself according to their strengths, such as java's object-oriented programming, the main goal of which was to allow developers to quickly write high-quality web websites. PHP supports both object-oriented and process-oriented development and is very flexible in use.

The application field of PHP

1) WEB server

PHP is particularly suitable for website development, and there is no language to compete with it (according to the authoritative technology website w3techs.com, PHP is used by 79% of websites).

Of course, the opportunity for PHP to show its talents is not only in website development, but also in game development, advertising system development, API interface development, mobile background development, and internal OA system development.

Nowadays, Wechat development is extremely popular, and PHP is also the best development tool. Coupled with the birth of react native framework and Hybrid App, PHP programmers can develop mobile App.

2) Command line script

We can also run PHP scripts in command-line mode, which does not require server support or browser trigger, but only PHP parsers in command-line script mode. This method is usually used for daily running scripts on Windows and Linux platforms, such as some daemons. Of course, these scripts can also be used to handle simple text.

3) write desktop applications

PHP may not be the best language for developing desktop applications with a graphical interface, but if users are very proficient in PHP and want to use some of PHP's advanced features in client applications, they can use PHP-GTK to write these programs.

PHP-GTK is an extension of PHP, using PHP-GTK to create stand-alone GUI (graphical user interface) applications, such as mp3 players, text editors, database backend, and so on. You can download PHP-GTK from http://gtk.php.net/.

What does python mean?

Python is an interpretive, object-oriented, dynamic data type high-level programming language. Like the Perl language, Python source code follows the GPL (GNU General Public License) protocol.

Python was designed by Guido van Rossum of the Dutch Society for Mathematical and computer Science Research in the early 1990s as an alternative to a language called ABC. Python provides efficient advanced data structures and simple and effective object-oriented programming. Python syntax and dynamic typing, as well as the nature of the interpreted language, make it a programming language for scripting and rapid development of applications on most platforms. With the continuous update of versions and the addition of new features of the language, it is gradually used for the development of independent and large-scale projects.

The Python interpreter is easy to extend to extend new functions and data types using C or C++ (or any other language that can be called through C). Python can also be used for extension program languages in customizable software. Python's rich standard library provides source code or machine code for all major system platforms.

On the whole, the most important feature of Python language is simplicity, which is mainly reflected in the following two aspects:

The syntax of the Python language is so concise that it is easy to use even for non-software beginners.

Compared with other programming languages, the implementation code of Python language is often the shortest to achieve the same function.

At this point, I believe you have a deeper understanding of "what php and python are". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
