刚开始使用Propel 2.0 ORM。所有教程都告诉我们以这种方式使用模式：
$ propel model:build 如何在不使用命令行的情况下创建，重新创建或更新模型和数据，而只是在php脚本中？可能需要创建CMS模块安装程序或类似的东西。

一种“重新发明轮子”的方法但我没有找到任何其他方法来使用没有CLI的Propel 2.
use Propel\Runtime\Propel;
use Propel\Generator\Command;
use Symfony\Component\Console\Input\ArrayInput;
use Symfony\Component\Console\Output\StreamOutput;
use Symfony\Component\Console\Application;
/**
* Class Commander
*
* A script-based approach to run Propel commands without the CLI.
*
* Usage:
*
* ```
* $cmd = new Commander('<propel_command>', '<command_arguments>');
* $cmd->run();
* ...
* $cmd->addCommand('<propel_command>', '<command_arguments>');
* $cmd->run();
* ```
*
* In case of migration tasks you must call
* ```
* ...->preMigrate(array('<path_to_schema_files_dir1>', ..., '<path_to_schema_files_dirN>'), '<temp_dir>');
* ```
* to gather all schemas together and analyze 'em with propel:diff.
*
* Then after the diff and migrate are complete you must call ``postMigrate()`` to remove temporary
* schema copies.

用法示例：
//Convert the configuration file
$cmd = new Commander('config:convert', '--config-dir='.$_SERVER['DOCUMENT_ROOT'].'/propeltest/config --output-dir='.$_SERVER['DOCUMENT_ROOT'].'/propeltest/config');
$cmd->run();
//... or (re)build models
$cmd = new Commander('model:build', '--schema-dir='.$_SERVER['DOCUMENT_ROOT'].'/propeltest/module/schema --output-dir='.$_SERVER['DOCUMENT_ROOT'].'/propeltest/module/models');
$cmd->run();
//... or perform database migration (actually not tested yet :/ )
$cmd = new Commander('migration:diff', '--schema-dir='.$_SERVER['DOCUMENT_ROOT'].'/propeltest/cache/schemacache');
$cmd->preMigrate([$_SERVER['DOCUMENT_ROOT'].'/propeltest/schema', $_SERVER['DOCUMENT_ROOT'].'/propeltest/module/schema'], $_SERVER['DOCUMENT_ROOT'].'/propeltest/cache/schemacache');
$cmd->run(); // runs migrate:diff
$cmd->addCommand('migration:diff', '--schema-dir='.$_SERVER['DOCUMENT_ROOT'].'/propeltest/cache/schemacache'); // prepare to actually migration
$cmd->run(); // perform migration:migrate
$cmd->postMigrate();
