Symfony2 + Doctrine：如何将iso8859-1转换为utf-8，反之亦然？

我用MSSQL实例解决了类似的问题，该实例将utf8转换为latin1，反之亦然。我执行以下步骤：

1. 定义自定义DBAL类型
2. 在Boot Bundle方法上初始化（我想您也可以这样做config.yml）
3. 将其用作实体字段上的注释

这是他的代码：

DBAL自定义类型

<?php
namespace Acme\DemoBundle\Doctrine\Type;

use Doctrine\DBAL\Types\StringType;
use Doctrine\DBAL\Platforms\AbstractPlatform;

class Utf8String extends StringType
{
    /**
     * {@inheritdoc}
     */
    public function convertToDatabaseValue($value, AbstractPlatform $p)
    {
        // convert from utf8 to latin1
        return mb_convert_encoding($value, 'ISO-8859-1', 'UTF-8');
    }

    /**
     * {@inheritdoc}
     */
    public function convertToPHPValue($value, AbstractPlatform $p)
    {
        // convert from latin1 to utf8
        return mb_convert_encoding($value, 'UTF-8', 'ISO-8859-1');
    }
}

捆绑初始化

<?php

namespace Acme\DemoBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;
use Doctrine\DBAL\Types\Type;

class AcmeDemoBundle extends Bundle
{
    public function boot() {

        if (!Type::hasType('utf8string'))
        {
            Type::addType('utf8string', 'Acme\DemoBundle\Doctrine\Type\Utf8String');

            $em = $this->container->get('doctrine.orm.em_my_sqlserver_entity_manager');
            $conn = $em->getConnection();
            $conn->getDatabasePlatform()->registerDoctrineTypeMapping('Utf8String', 'utf8string');
        }
    }

}

映射实体示例

<?php

namespace Acme\DemoBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 *
 * @ORM\Table(name="VEHICLE")
 * @ORM\Entity()
 */
class Vehicle
{

    /**
     * @ORM\Id
     * @ORM\Column(name="VEHICLE_NAME", type="utf8string", length=16, nullable=false)
     */
    private $name;


    /**
     * @var integer
     *
     * @ORM\Column(name="ID_VEHICLE", type="integer", nullable=true)
     */
    private $idVehicle;

....
}
