如何从蛋糕外壳读取数据库配置设置?

cakephp

Randy L · 技术社区 · 15 年前

我想写一个蛋糕外壳,用mysqldump每晚备份我的数据库。我可以把它作为shell脚本来完成,但是如果我能把它塞进一个cakephp shell中,那么我将从它在开发和实时服务器上工作中获得额外的好处,如果我能让它自动读取我的数据库配置设置。我会选择蛋糕壳,并且知道我有数据库的频繁备份,我会有一些平静的想法。

在我的shell中,我试图构建一个以“mysqldump--user=”开头的字符串,我想从app/config/database.php获取用户名。如何获取database.php中的数据?

use Cake\Datasource\ConnectionManager;
$source = ConnectionManager::get('default');

debug($source); #Debugging the result

object(Cake\Database\Connection) {

App::uses('ConnectionManager', 'Model');
$dataSource = ConnectionManager::getDataSource('default');
$username = $dataSource->config['login'];
