slim：项目应用（二）数据库

项目应用（二）数据库

数据库使用doctrine orm，doctrine的依赖包含了后面会用到的symfony/console组件

• 安装doctrine orm

composer require doctrine/orm

• 新建cli配置

# config/cli-config.php


use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Tools\Console\ConsoleRunner;
use Slim\Container;

/** @var Container $container */
$container = require_once APP_ROOT . '/src/bootstrap.php';

ConsoleRunner::run(
    ConsoleRunner::createHelperSet($container[EntityManager::class])
);

• 新建bootstrap

# src/bootstrap.php


use Doctrine\Common\Annotations\AnnotationReader;
use Doctrine\Common\Cache\FilesystemCache;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Mapping\Driver\AnnotationDriver;
use Doctrine\ORM\Tools\Setup;
use Slim\Container;

require_once APP_ROOT . '/vendor/autoload.php';

(new \Symfony\Component\Dotenv\Dotenv(false))->loadEnv(APP_ROOT . "/.env.local");

$env = $_ENV['APP_ENV']??'local';

$container = new Container(require APP_ROOT . "/config/config.$env.php");

$container[EntityManager::class] = function (Container $container): EntityManager {
    $config = Setup::createAnnotationMetadataConfiguration(
        $container['settings']['doctrine']['metadata_dirs'],
        $container['settings']['doctrine']['dev_mode']
    );

    $config->setMetadataDriverImpl(
        new AnnotationDriver(
            new AnnotationReader,
            $container['settings']['doctrine']['metadata_dirs']
        )
    );

    $config->setMetadataCacheImpl(
        new FilesystemCache(
            $container['settings']['doctrine']['cache_dir']
        )
    );

    return EntityManager::create(
        $container['settings']['doctrine']['connection'],
        $config
    );
};

return $container;

• 新建可执行文件

# bin/doctrine


define('APP_ROOT', dirname(__DIR__));

@include APP_ROOT . "/vendor/bin/doctrine";

• 新建entity

# 这是我的一个例子
# src/Entity/Data.php
# 里面的注释不能少，参考vendor/doctrine/annotations，文档:https://github.com/doctrine/annotations

}

• 使用

参考src/controller/TestDoctrine.php

建议先了解doctrine orm的使用教程

• PS

如果出现 'SQLSTATE[HY000] [2002] No such file or directory' 错误，请指定 php.ini 的 'pdo_mysql.default_socket' 配置
