laravel 的 artisan 命令行太好用了，換個框架沒有這個功能，于是自己學習實現一些，直接上代碼

?

新建目錄

-artisan

--bin

--src

進入artisan composer init? ??

composer require symfony/console

?

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

use Symfony\Component\Console\Application;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

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();

以上是簡單的實現



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

use Symfony\Component\Console\Application;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Input\InputArgument;

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();

這里演示了如何接收參數



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

use Symfony\Component\Console\Application;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputOption;

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,'轉換字符串大小','lower')
;

$app->run();

exit();

這里演示了如何給命令行添加選項 ./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}");

可以給它們加上顏色

接下來將命令行拆分為文件

bin/artisan.php

ArtisanCommand.php

?

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

use Symfony\Component\Console\Application;
use Artisan\ArtisanCommand;
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 Symfony\Component\Console\Application;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Command\Command;

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,'轉換字符串大小','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，還有其他功能可以去看Symfony文檔
