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
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();
以上是简单的实现
#!/usr/bin/env 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();
这里演示了如何接收参数
#!/usr/bin/env 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,'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
$output->writeln("hello {$name}");
$output->writeln("hello {$name}");
$output->writeln("hello {$name}");
$output->writeln("hello {$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
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
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,'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);
}
$output->writeln("hello {$name}");
$output->writeln("hello {$name}");
$output->writeln("hello {$name}");
$output->writeln("hello {$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
