Is swoole faster than native PHP?

#swoole is faster than native PHP.

Swoole’s introduction:

PHP’s asynchronous, parallel, high-performance network communication engine, written in pure C language, provides an asynchronous multi-threaded server in PHP language, asynchronous TCP/ UDP network client, asynchronous MySQL, asynchronous Redis, database connection pool, AsyncTask, message queue, millisecond timer, asynchronous file reading and writing, asynchronous DNS query.

Swoole has built-in Http/WebSocket server/client and Http2.0 server. )

Why does PHP need to supplement swoole

Compared with apache/fpm, the swoole framework mainly saves the performance loss caused by the creation and destruction of the PHP framework and global objects for each request.

The swoole framework provides programmers with the greatest space, and global objects unrelated to http requests only need to be constructed once. Cache control can also be performed on certain objects and data in the program.

PHP is the best language. Swoole has redefined the best language. This is of course a joke, but PHP is a language with low entry-level, fast development and high execution efficiency. In the era of PC Internet, which is famous for its speed, it has become the undisputed first choice. This is the advantage of PHP.

Then the advantage slowly transformed into a mindset. In the eyes of many engineers, PHP development is equivalent to web development. However, now is the era of mobile Internet, the Internet of Things, and smart hardware are also booming. It seems PHP is not so popular anymore (ps: it has always been the case), and the emergence of swoole has successfully broken through this mindset, allowing PHP to jump out of web development.

has entered the larger field of server network programming, but web development and server network programming are still very different in development thinking. This series of articles will help everyone make thinking changes through the introduction of swoole, so as to Enter a new world.

The relationship between PHP and SWOOLE

Swoole is an extension of PHP, developed purely in C, mainly to supplement PHP's deficiencies in network programming

PHP and SWOOLE operating modes

php is the host of swoole, so it is essential to understand the operating mode of php itself. The following figure is the complete process of executing a php file under cli

There is a concept of SAPI in this upper layer. SAPI is a unified interface provided by PHP for the external environment to execute the PHP kernel. Our three common SAPIs are cli, php-fpm, and mod_php. .
