This article mainly introduces the relevant knowledge of "what is the reason for running Laravel on Swoole". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "what is the reason for running Laravel on Swoole" can help you solve the problem.

Swoole is a production-level asynchronous programming framework developed for PHP. It is a pure C development extension that allows PHP developers to write high-performance, extensible concurrent TCP, UDP, Unix socket, HTTP, WebSocket services in PHP without having too much knowledge of non-blocking Itemo programming and low-level Linux kernels. You can think of Swoole as NodeJS, but there will be higher performance for PHP.

Why run Laravel on Swoole?

The following figure shows the life cycle of PHP. As you can see, every time you run a PHP script, PHP needs to initialize the module and start the Zend engine for your runtime environment. And compile the PHP script to OpCodes for execution by the Zend engine.

However, such a lifecycle needs to be executed every time it is requested. Because the environment created by a single request is destroyed immediately after the completion of the request execution.

In other words, in the traditional PHP lifecycle, a lot of time is wasted creating and destroying resources for script execution. Imagine a framework like Laravel, how many files need to be loaded in each request? At the same time, it also wastes a lot of Istroke O operations.

So what if we use Swoole to build an application-level Server, and all script files can be saved in memory after loading once? That's why we need to try running Laravel on Swoole. Swoole can provide powerful performance while Laravel can provide elegant code structure. These two are a perfect match!

Installation

The following are the main features of swooletw/laravel-swoole:

Run the Laravel/Lumen application in Swoole

Excellent performance up to 30x

Sandboxie mode isolation application container

Support for running WebSocket servers in Laravel applications

Support for Socket.io protocol

Support sharing of Swoole tables across processes

Install using Composer:

$composer require swooletw/laravel-swoole

This package depends on Swoole. Before using this package, make sure that your machine has the correct Swoole installed. Quickly install (linux) using the following command:

Pecl install swoole

After installing this extension, you need to edit php.ini to add extension=swoole.so.

Php-I | grep php.ini # check the php.ini file locationsudo echo "extension=swoole.so" > > php.ini # add the extension=swoole.so to the end of php.iniphp-m | grep swoole # check if the swoole extension has been enabled

Visit the official website for more information.

Note: Swoole now only supports Linux and OSX. The Windows server does not support it yet.

Then, add the service provider:

If you use Laravel, add the service provider to the config/app.php service provider array:

['providers' = > [SwooleTW\ Http\ LaravelServiceProvider::class,],]

If you use Lumen, add the following code to bootstrap/app.php:

$app- > register (SwooleTW\ Http\ LumenServiceProvider::class)

This package supports automatic packet discovery. If you are running Laravel version 5.5 or later, you can skip this step.

Set up and run

Now, you can execute the following command to start the Swoole HTTP service.

$php artisan swoole:http start

Then you can see the following message:

Starting swoole http server...Swoole http server started:

You can now enter the Laravel application by visiting http://127.0.0.1:1215.
