php is the scripting language.

The full name of PHP is PHP Hypertext Preprocessor, which means "hypertext preprocessor". It is an embedded scripting language. Due to its simplicity, ease of use, cross-platform, open source and other characteristics, PHP makes it It has become a mainstream website development language, and websites developed using PHP can be found in various industries.

PHP is a cross-platform, open source, free scripting language that is executed on the server side. It is especially suitable for web development and can be embedded in HTML.

PHP syntax learned the C language, absorbed the characteristics of multiple languages ​​​​of Java and Perl to develop its own unique syntax, and continued to improve itself based on their strengths, such as Java's object-oriented programming. The language was originally The main goal of its creation is to allow developers to quickly write high-quality web sites. PHP supports both object-oriented and process-oriented development, and is very flexible in use.

PHP language features:

• Open source and free

  PHP is an open source software project with a large audience and many developers , Linux Nginx Mysql PHP is its classic installation and deployment method. All related software is open source and free, so using PHP can save a lot of genuine licensing fees. However, as an open source software, PHP lacks the support background of large technology companies, and its pessimism on the Internet is also enduring. However, the reality of its continuous iteration and performance enhancement is inspiring. The PHP community uses practical actions to Give a strong reply to all kinds of doubts.

• Fast and efficient

  The core of PHP is based on the C language and is very efficient. You can use C language to develop high-performance extension components; the core of PHP contains a number of There are more than 1,000 built-in functions, all the functions are very comprehensive, and the program code that can be used out of the box is simple;

  PHP arrays support dynamic expansion and support associative arrays with numbers, strings or mixed key names, which can greatly improve development efficiency ;

  PHP is a weakly typed language, with a high program compilation pass rate and faster development efficiency than other strongly typed languages;

  PHP is naturally hot-deployed, and the code file is in the php-fpm running mode Coverage completes hot deployment;

  After more than 20 years of development, PHP can find a large number of reference materials on the Internet for reference and study.

• Performance improvement

  The higher the PHP version, the higher its overall performance. According to the official introduction, the performance of PHP7.0.0 [14] has improved by 2 compared to PHP5.6 Times, PHP7.4 is already about 30% faster than PHP7.0, and PHP8.0 has improved performance by about 10% relative to PHP7.4.

  PHP 8.0 introduces JIT compiler features and adds a variety of new language features, such as named parameters, union types, annotations, Constructor Property Promotion, match expressions, nullsafe operators, and support for type systems and errors Handling and consistency improvements. PHP has its own core development team, which maintains the frequency of releasing one major version every five years and two minor versions every month. The latest version is PHP8.08.

• Cross-platform

  Each platform has a corresponding PHP interpreter version, which means that the binary code (PHP interpreter) of the target platform is compiled for different platforms. Programs developed in PHP can run on multiple operating systems such as windows, linux, and unix without modification.

• Resident memory

  In php-cli mode, the program can be resident in memory. Various variables and database connections can be stored in memory for a long time to achieve resource reuse. A more common approach is to write the cli framework in combination with the swoole component.

• Page life cycle

  In php-fpm mode, all variables are page-level, whether they are global variables or static members of the class, they will be on the page It is cleared after execution. It requires low programmer skills and takes up very little memory. It is especially suitable for the development of small and medium-sized systems.

Application fields of PHP

1) WEB server

PHP is especially suitable for website development, and no language can match it Competing (according to statistics from the authoritative technology website w3techs.com, PHP is used by 79% of websites).

Of course, PHP can be used not only in website development, but also in game development, advertising system development, API interface development, mobile backend development, and internal OA system development.

Nowadays, WeChat development is extremely popular, and PHP is also the best development tool. With the birth of the react native framework and Hybrid App, PHP programmers can even develop mobile apps.

2) Command line script

We can also run PHP scripts through the command line mode. This mode does not require server support or browser triggering. In the command line script mode, only the PHP parser is required for execution. Usually this method is used for daily running scripts under Windows and Linux platforms, such as certain daemons, etc. Of course these scripts can also be used to process simple text.

3) Writing desktop applications

PHP may not be the best language for developing desktop applications with graphical interfaces, but if the user is very proficient in PHP and wants to If you use some advanced features of PHP in client applications, you can use PHP-GTK to write these programs.

PHP-GTK is an extension of PHP. Using PHP-GTK, you can create independent GUI (graphical user interface) applications, such as mp3 players, text editors, database backends, etc. PHP-GTK can be downloaded from http://gtk.php.net/.

Note: So far, there is still no programming language on the market that is simpler and easier to use than PHP. Even famous websites around the world are using PHP. Please see the table below
