安装

composer require codememory/database-connection

支持的驱动程序

• MySQL
• PostgreSQL
• SQLite

Connection 类的方法

• getConnector(): ConnectorInterface 获取连接器
  • string $connectorName
• getConnectors(): ConnectorInterface[] 获取所有连接器的数组
• reconnect(): ConnectorInterface|ConnectionInterface 重新定义连接器数据
  • string $connectorName
  • callable $callback
  • string|null $newConnectorName
• connectorExist(): bool 检查连接器是否存在
  • string $connectorName

Connector 类的方法

• isConnection(): bool 检查是否已连接到数据库
• getConnection(): PDO 如果连接成功，获取 PDO 对象
• getConnectorData(): ConnectorConfigurationInterface 获取已连接用户的配置数据
• getConnectorName(): string 获取当前连接器的名称

创建连接器的示例

<?php

use Codememory\Components\Database\Connection\Connection;
use Codememory\Components\Database\Connection\Interfaces\ConnectorConfigurationInterface;
use Codememory\Components\Database\Connection\Drivers\MySQLDriver;

require_once 'vendor/autoload.php';

$connection = new Connection();

// Добавление коннектора в список всех коннекторов
$connection->addConnector('connector-name', function (ConnectorConfigurationInterface $configuration) {
    $configuration
        ->host('localhost')
        ->dbname('dbname')
        ->username('username')
        ->password('user password')
        ->driver(new MySQLDriver())
});

重定义连接器数据的示例

// Возьмем ранее добавленный коннектор "connector-name"

$connection->reconnect('connector-name', function (ConnectorConfigurationInterface $configuration) {
    $configuration->dbname('new-dbname');
});

$connection
    ->getConnector('connector-name')
    ->getConnectorData()
    ->getDbname(); // new-dbname
