Question

我已经整合了学说ORM和codeigniter（都有最新版本）
mysql表实体也是由doctrine创建的但是没有使用学说实体从数据库中获取数据的知识我用下面的结构来整合学说和代码签名 https://github.com/pedrozok/codeigniter-doctrine-bootstrap
我修改了doctrine库，如下所示。

<?php

defined('BASEPATH') OR exit('No direct script access allowed');

use Doctrine\Common\ClassLoader,
    Doctrine\ORM\Tools\Setup,
    Doctrine\ORM\EntityManager,
    Doctrine\ORM\Mapping\Driver\DatabaseDriver,
    Doctrine\ORM\Tools\DisconnectedClassMetadataFactory,
    Doctrine\ORM\Tools\EntityGenerator,
    Doctrine\Common\Cache\ApcCache;

class Doctrine {

    public $em;

    public function __construct() {
        require_once __DIR__ . '/Doctrine/ORM/Tools/Setup.php';
        Setup::registerAutoloadDirectory(__DIR__);

        if (!file_exists($file_path = APPPATH . 'config/' . ENVIRONMENT . '/database.php') && !file_exists($file_path = APPPATH . 'config/database.php')) {
            throw new Exception('The configuration file database.php does not exist.');
        }
        require $file_path;

        $connection_options = array(
            'driver' => 'pdo_mysql',
            'user' => $db['default']['username'],
            'password' => $db['default']['password'],
            'host' => $db['default']['hostname'],
            'dbname' => $db['default']['database'],
            'charset' => $db['default']['char_set'],
            'driverOptions' => array(
                'charset' => $db['default']['char_set'],
            ),
        );

        // With this configuration, your model files need to be in application/models/Entity
        // e.g. Creating a new Entity\User loads the class from application/models/Entity/User.php
        $models_namespace = 'Entity';
        $models_path = APPPATH . 'models';
        $proxies_dir = APPPATH . 'models/Proxies';
        $metadata_paths = array(APPPATH . 'models');
        $extension_dir = APPPATH . 'libraries/Doctrine';

        // Set $dev_mode to TRUE to disable caching while you develop
        $config = Setup::createAnnotationMetadataConfiguration($metadata_paths, $dev_mode = true, $proxies_dir);

        // Proxy configuration
        $config->setProxyDir(APPPATH . '/models/proxies');
        $config->setProxyNamespace('Proxies');

        $this->em = EntityManager::create($connection_options, $config);
        /* code added to handle enum datatype starts here */
        $platform = $this->em->getConnection()->getDatabasePlatform();
        $platform->registerDoctrineTypeMapping('enum', 'string');
        /* ends enum code */

        $loader = new ClassLoader($models_namespace, $models_path);
        $loader->register();
        /**
         * generate entities from database
         * @return none
         */
        // $this->generate_doctrine_entities($this->em, APPPATH . "models/Entity");
        /* ends */
        //$this->create_update_database($this->em, "update");
    }

    function generate_doctrine_entities($em, $path) {

        $em->getConfiguration()->setMetadataDriverImpl(
                new DatabaseDriver($this->em->getConnection()->getSchemaManager())
        );

        $cmf = new DisconnectedClassMetadataFactory();
        $cmf->setEntityManager($em);
        $metadata = $cmf->getAllMetadata();
        $generator = new EntityGenerator();
        $generator->setRegenerateEntityIfExists(false);
        $generator->setUpdateEntityIfExists(true);
        $generator->setGenerateStubMethods(true);
        $generator->setGenerateAnnotations(true);
        $generator->generate($metadata, $path);
    }

    function create_update_database($em, $mode = "update") {

        $tool = new \Doctrine\ORM\Tools\SchemaTool($em);

        $cmf = new \Doctrine\ORM\Tools\DisconnectedClassMetadataFactory();
        $cmf->setEntityManager($em);
        $metadata = $cmf->getAllMetadata();

        if ($mode == "create") {
            $queries = $tool->getCreateSchemaSql($metadata);
        } else {
            $queries = $tool->getUpdateSchemaSql($metadata);
        }
        echo "Total queries: " . count($queries) . "<br /><br />";
        for ($i = 0; $i < count($queries); $i++) {
            $em->getConnection()->prepare($queries[$i])->execute();
            echo $queries[$i] . "<br /><br />Execution Successful: " . ($i + 1) . "<br /><br />";
        }
    }

}

是否有任何建议将doctrine实体包含在codeigniter模型中并从实体获取数据？

以下是一些代码示例对您有帮助吗？

// Fetch data by Native SQL
// $em is entity manager
$sql = "SELECT * FROM userView ";
// $em = $this->getDoctrine()->getManager();
$stmt = $em->getConnection()->prepare($sql);
$stmt->execute();
  \Doctrine\Common\Util\Debug::dump( $stmt->fetchAll() );

//fetching data in by DQL
$qb = $em->getRepository('User')->createQueryBuilder('u');
//$qb->andWhere('u.id = :id')->setParameter('id', $id);
$data = $qb->getQuery()->getResult( ); // in objects

$data = $qb->getQuery()->getResult(Query::HYDRATE_ARRAY); // in array

 echo '<pre>'; \Doctrine\Common\Util\Debug::dump($data);
// Fetching data by common way
$data = $em->getRepository('User');
$datax = $data->findAll();

foreach($datax as $d) {
  echo '<pre>'; \Doctrine\Common\Util\Debug::dump($d);

使用doctrine codeigniter获取记录
