In the Laravel project, if you have installed PHP locally and you want to use PHP's built-in server to provide services for your application, you can use the Artisan command serve. The command is displayed in the http://localhost:8000 Start the development server on
1, How do I start the PHP built-in server?
php artisan serve
You can also specify host and port to start, mainly using -- host and -- port parameters
1.1 specify port number
php artisan serve --port 8001
1.2 specify the host. You can use ip or domain name
php artisan serve --host 127.0.0.2 --port 8001
2, How does the php artisan serve command run?
Some people are curious about why you can run the service by executing this command?
In fact, since PHP version 5.4, PHP has built in a web server, and Laravel's artists command also supports the built-in web server, which makes the quick start service more efficient. Of course, if you want to deploy to a production server, you still need to install a web server such as apache or nginx.
Next, let's analyze the command of laravel: php artisan serve
2.1 source file ServeCommand.php
Note: the laravel project is based on version 6.20.26
The source file is Src / illuminate / foundation / console / servercommand.php

2.2 source file analysis
We can know through the handle() method
2.2.1 change execution root directory
First, use chdir() to change the directory to the public / directory
chdir(public_path());
PHP
Copy

2.2.3 execute command
The execution command is implemented through the native function passthru() of passthru (this - > servercommand()), where
passthru($this->serverCommand(), $status);
PHP
Copy
/** * Get the full server command. * * @return string */ protected function serverCommand() { return sprintf('%s -S %s:%s %s', ProcessUtils::escapeArgument((new PhpExecutableFinder)->find(false)), $this->host(), $this->port(), ProcessUtils::escapeArgument(base_path('server.php')) ); }PHP
Copy
The four string placeholders of sprintf() will be replaced by the four parameters passed in later. Finally, an executable PHP command will be printed, of which the four correspond to:
//php executable full path processutils:: Escape argument ((New phpexecutablefinder) - > find (false))
//Host, the default is 127.0.0.1 $this - > host ()
//Port, the default is 8000 $this - > port ()
//Full path to execute code processutils:: Escape argument (base_path ('server. PHP '))So what does serverCommand() return in the end? We can print it directly:
Printed results:
Therefore, we can conclude that the php artisan serve command directly uses php to execute the server.php file, which is located in the root directory of the project. For example, it is equivalent to directly executing the following command on the command line:
php -S 127.0.0.1:8001 server.php
2.2.4 final
The php artisan serve command actually uses php to directly execute files, which is not much different from the built-in server using php -S 127.0.0.1:8001 PHP.
