我尝试使用 2 个 PDO 数据库连接设置 SLIM 4。
我无法从存储库访问 db 或 db2。
我想我做错了什么
我跟着苗条的4骨架。
我在应用程序中创建了一个 db.php 文件，用于在容器中添加 db 的定义
我在 index.php 中包含 db.php 我试图从存储库访问 db 或 db2，但它不起作用
这是我的文件：
应用程序/db.php
declare(strict_types=1);
use PDO;
use DI\ContainerBuilder;
return function (ContainerBuilder $containerBuilder) {
// Global Settings Object
$containerBuilder->addDefinitions([
'db' => function (ContainerInterface $c) {
$settings = $c->get('settings');
$dbSettings = $settings['db'];
return new PDO('mysql:host=' . $dbSettings['host'] . ';dbname=' . $dbSettings['db'], $dbSettings['username'], $dbSettings['password'], $dbSettings['options']);
},
'db2' => function (ContainerInterface $c) {
$settings = $c->get('settings');
$dbSettings = $settings['db2'];
return new PDO('mysql:host=' . $dbSettings['host'] . ';dbname=' . $dbSettings['db'], $dbSettings['username'], $dbSettings['password'], $dbSettings['options']);
}
]);
};
