Parsing PHP 5 and PHP 7 code into an abstract syntax tree (AST).

The AST contains accurate location information.

Dumping the AST in human-readable form.
Converting an AST back to PHP code.

Console组件允许你创建command-line命令。你的console（控制台）命令可以用于任何反复（执行）的任务，比如cronjobs，imports（导入），或其他批处理工作。

安装 ¶
你可以通过下述两种方式安装：

通过Composer安装（Packagist上的symfony/console）

通过官方Git宝库（https://github.com/symfony/console）

然后，包容vendor/autoload.php文件，以开启Composer提供的自动加载机制。否则，你的程序将无法找到这个Symfony组件的类。

创建一个Console程序 ¶
首先，你要建立一个PHP脚本来定义控制台程序：
#!/usr/bin/env php
<?php
// application.php

require DIR.’/vendor/autoload.php’;

use Symfony\Component\Console\Application;

$application = new Application();

// … register commands / 注册命令

$application->run();
然后，你可以用add()来注册这个命令：
// …
$application->add(new GenerateAdminCommand());
