待办事项

• 添加 ->match($something) 简写

备注

• 如果你独立使用此库并且需要事件，请要求 illuminate/events 并将一个 Dispatcher 实例设置到你的 SphinxConnection 中以接收事件。
• 如果你使用此包与 Laravel 一起，请参考 \Illuminate\Database\Connection::resolverFor，在那里你可以设置一个工厂回调函数，它接受与 ConnectionFactory::createConnection 相同的参数。

示例用法

<?php

namespace MyApp\SomeFactory;

use Illuminate\Container\Container;
use Illuminate\Database\Connectors\MySqlConnector;
use Illuminate\Database\Events\StatementPrepared;
use Illuminate\Events\Dispatcher;
use Wucdbm\Component\SphinxQueryBuilder\SphinxConnection;

class ConnectionFactory {

    // Example simple usage
    public static function create(
        string $driver, string $host, string $port,
        string $db, string $user, string $pass
    ): SphinxConnection {
        $config = [
            'driver'    => $driver,
            'host'      => $host,
            'port'      => $port,
            'database'  => $db,
            'username'  => $user,
            'password'  => $pass,
            'charset'   => 'utf8',
            'prefix'    => '',
        ];

        $connector = new MySqlConnector();
        $pdo = $connector->connect($config);

        return new SphinxConnection($pdo, $config['database'], $config['prefix'], $config);
    }
   
    // Attach an event dispatcher and force fetch mode to `\PDO::FETCH_ASSOC` 
    public static function withEvents(
        SphinxConnection $c
    ): Dispatcher {
        $dispatcher = new Dispatcher(new Container());
        $c->setEventDispatcher($dispatcher);

        $dispatcher->listen(StatementPrepared::class, static function(StatementPrepared $event) {
            $statement = $event->statement;
            $statement->setFetchMode(\PDO::FETCH_ASSOC);
        });

        return $dispatcher;
    }

}

<?php

$connection = \MyApp\SomeFactory\ConnectionFactory::create(
    'sphinx', '127.0.0.1', '9306',
    '', '', ''
);
$dispatcher = \MyApp\SomeFactory\ConnectionFactory::withEvents($connection);
