使用方式

如果你用过 Laravel、或者单独用过 illuminate/database 包,那么使用起来得心应手,因为写法基本一致。

<?php

require_once 'vendor/autoload.php';

use Raylin666\Database\Pdo\DbConfig;
use Raylin666\Database\Pdo\PDO;
use Raylin666\Database\Pdo\Connection;

use Raylin666\Database\Pool\DatabasePool;
use Raylin666\Pool\PoolConfig;
use Raylin666\Pool\PoolOption;
use Raylin666\Database\Model;

// 设置 DB 配置
$config = (new DbConfig())
    ->withName('default')
    ->withHost('127.0.0.1')
    ->withPort(3306)
    ->withDbname('im-server')
    ->withUsername('raylin666')
    ->withPassword('123456')
    ->withTablePrefix('im_')
    ->withOptions([
        // \PDO::ATTR_CASE => \PDO::CASE_UPPER,    // 将字段名称转换为大写
    ]);
// 配置 PDO
$pdo = new PDO($config);
// 创建连接
$connection = (new Connection($pdo))();
// 设置 SQL 日志监听 (如打印SQL日志)
$connection->getConnection()->getEventDispatcher()->listen(
    Illuminate\Database\Events\QueryExecuted::class,
    function ($event) {
        var_dump($event->sql);
    }
);

// 连接池模式
$poolOption = new PoolOption();
$poolOption->withMinConnections(10)
    ->withMaxConnections(100);
$poolConfig = new PoolConfig('local', function () use ($connection) {
    return $connection;
}, $poolOption);
$pool = new DatabasePool($poolConfig);

/***********************************************
 * 非常驻内存环境下使用方式 (非Swoole)

// 初始化数据库连接配置
DB::newManagerConnection($connection);

// 初始化数据库连接配置
DB::newManagerConnection($pool);

// 查询 SQL
DB::connection('default')->table('account')->first();
DB::connection('local')->table('account')->first();

// Model 模型操作
class Account extends Model
{
    protected $connection = 'default';

    protected $table = 'account';
}

// Model 查询
Account::where(['id' => 6])->first()->toArray();

    // 模拟并发请求
    $waitGroup = new Swoole\Coroutine\WaitGroup();
    for ($i = 0; $i < 1000; $i++) {
        $waitGroup->add();
        go(function () use ($waitGroup, &$count) {

    }
});
