laravel 的 artisan 命令行太好用了，换个框架没有这个功能，于是自己学习实现一些，直接上代码

新建目录

-artisan

--bin

--src

进入artisan composer init

composer require symfony/console

#!/usr/bin/env php
<?php

use SymfonyComponentConsoleApplication;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;

require_once __DIR__.'/../vendor/autoload.php';

$app = new Application('artisan','1.1.1');

$app->register('artisan')->setCode(function(InputInterface $input, OutputInterface $output){
 $output->writeln('artisan start');
});

$app->run();

exit();

以上是简单的实现

#!/usr/bin/env php
<?php

use SymfonyComponentConsoleApplication;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;
use SymfonyComponentConsoleInputInputArgument;

require_once __DIR__ . '/../vendor/autoload.php';

$app = new Application('artisan', '1.1.1');

$app->register('artisan')
 ->setDescription('myself artisan description')
 ->setCode(
 function (InputInterface $input, OutputInterface $output) {
 $name = $input->getArgument('name');
 $output->writeln("hello {$name}");
 }
 )->addArgument('name', InputArgument::REQUIRED, 'please input your name');

$app->run();

exit();

这里演示了如何接收参数

#!/usr/bin/env php
<?php

use SymfonyComponentConsoleApplication;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;
use SymfonyComponentConsoleInputInputArgument;
use SymfonyComponentConsoleInputInputOption;

require_once __DIR__ . '/../vendor/autoload.php';

$app = new Application('artisan', '1.1.1');

$app->register('artisan')
 ->setDescription('myself artisan description')
 ->setCode(
 function (InputInterface $input, OutputInterface $output) {
 $string = $input->getOption('string');
 $name = $input->getArgument('name');
 if($string == 'lower'){
 $name = strtolower($name);
 }
 if($string == 'upper'){
 $name = strtoupper($name);
 }
 $output->writeln("hello {$name}");
 }
 )->addArgument('name', InputArgument::REQUIRED, 'please input your name')
 ->addOption('string',null,InputOption::VALUE_OPTIONAL,'转换字符串大小','lower')
;

$app->run();

exit();

这里演示了如何给命令行添加选项 ./bin/artisan.php artisan ffff --string='upper' echo FFFF

$output->writeln("<info>hello {$name}</info>");
$output->writeln("<error>hello {$name}</error>");
$output->writeln("<comment>hello {$name}</comment>");
$output->writeln("hello {$name}");

可以给它们加上颜色

接下来将命令行拆分为文件

bin/artisan.php

ArtisanCommand.php

#!/usr/bin/env php
<?php

use SymfonyComponentConsoleApplication;
use ArtisanArtisanCommand;
require_once __DIR__ . '/../vendor/autoload.php';

$app = new Application('artisan', '1.1.1');

$app->add(new ArtisanCommand());

$app->run();

exit();


ArtisanCommand.php

<?php
namespace Artisan;

use SymfonyComponentConsoleApplication;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;
use SymfonyComponentConsoleInputInputArgument;
use SymfonyComponentConsoleInputInputOption;
use SymfonyComponentConsoleCommandCommand;

class ArtisanCommand extends Command{
 public function configure()
 {
 $this->setName('artisan');
 $this->setDescription('myself artisan description')
 ->addArgument('name', InputArgument::REQUIRED, 'please input your name')
 ->addOption('string',null,InputOption::VALUE_OPTIONAL,'转换字符串大小','lower');
 }

 public function execute(InputInterface $input, OutputInterface $output)
 {
 $string = $input->getOption('string');
 $name = $input->getArgument('name');
 if($string == 'lower'){
 $name = strtolower($name);
 }
 if($string == 'upper'){
 $name = strtoupper($name);
 }
 $output->writeln("<info>hello {$name}</info>");
 $output->writeln("<error>hello {$name}</error>");
 $output->writeln("<comment>hello {$name}</comment>");
 $output->writeln("hello {$name}");
 }
}

composer.json

{
 "name": "baidu/artisan",
 "authors": [
 {
 "name": "gaobingbing",
 "email": "v_gaobingbing01@baidu.com"
 }
 ],
 "require": {
 "symfony/console": "^4.3"
 },
 "autoload": {
 "psr-4": {
 "Artisan": "src"
 }
 }
}

至此大功告成，还有其他功能可以去看Symfony文档
