首先通过 composer 安装
composer require topthink/think-migration
注意事项，不支持修改文件配置目录
在命令行下运行查看帮助，可以看到新增的命令
php think
migrate migrate:create Create a new migration migrate:rollback Rollback the last or to a specific migration migrate:run Migrate the database migrate:status Show migration status optimize optimize:autoload Optimizes PSR0 and PSR4 packages to be loaded wit h classmaps too, good for production. optimize:config Build config and common file cache. optimize:route Build route cache. optimize:schema Build database schema cache. seed seed:create Create a new database seeder seed:run Run database seeders
创建迁移类，首字母必须为大写
php think migrate:create Users
可以看到目录下有新文件 .\database\migrations\20161117144043_users.php
使用实例
<?php
use Phinx\Migration\AbstractMigration;class Users extends AbstractMigration{/**
* Change Method.
*/public function change(){// create the table$table = $this->table('users',array('engine'=>'MyISAM'));
$table->addColumn('username', 'string',array('limit' => 15,'default'=>'','comment'=>'用户名，登陆使用'))
->addColumn('password', 'string',array('limit' => 32,'default'=>md5('123456'),'comment'=>'用户密码'))
->addColumn('login_status', 'boolean',array('limit' => 1,'default'=>0,'comment'=>'登陆状态'))
->addColumn('login_code', 'string',array('limit' => 32,'default'=>0,'comment'=>'排他性登陆标识'))
->addColumn('last_login_ip', 'integer',array('limit' => 11,'default'=>0,'comment'=>'最后登录IP'))
->addColumn('last_login_time', 'datetime',array('default'=>0,'comment'=>'最后登录时间'))
->addColumn('is_delete', 'boolean',array('limit' => 1,'default'=>0,'comment'=>'删除状态，1已删除'))
->addIndex(array('username'), array('unique' => true))
->create();
}/**
* Migrate Up.
*/public function up(){
}/**
* Migrate Down.
*/public function down(){
}
}对于同一个数据表，如果需要新的迁移动作，例如删除字段、创建字段，可以创建新的更改文件，像svn一样往前记录操作，方便回滚。
