加载声明必须与... FixtureInterface :: load()兼容

Question

我正在创建一个需要加载功能的Doctrine数据夹具.我文字从FixtureInterface.php复制了该方法,但不知何故,我的夹具的load()有所不同.

PHP Fatal error:  Declaration of PastonVerBundle\DataFixtures\ORM\LoadTimeZoneData::load() must be compatible with that of Doctrine\Common\DataFixtures\FixtureInterface::load() in /var/www/symfony/src/Paston/VerBundle/DataFixtures/ORM/LoadTimeZoneData.php on line 9

我的负荷:

<?php

namespace PastonVerBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\FixtureInterface;
use Paston\VerBundle\Entity\TimeZone;

class LoadTimeZoneData 
    implements FixtureInterface {

    function load(ObjectManager $manager) {

        $z = new \TimeZone();
        $z->setName('Timezone');
        $manager->persist($z);
        $manager->flush();
    }

}

?>

从FixtureInterface.php加载

namespace Doctrine\Common\DataFixtures;

use Doctrine\Common\Persistence\ObjectManager;

/**
 * Interface contract for fixture classes to implement.
 *
 * @author Jonathan H. Wage <jonwage@gmail.com>
 */
interface FixtureInterface
{
    /**
     * Load data fixtures with the passed EntityManager
     *
     * @param Doctrine\Common\Persistence\ObjectManager $manager
     */
    function load(ObjectManager $manager);
}

你错过了use Doctrine\Common\Persistence\ObjectManager;:

namespace PastonVerBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\FixtureInterface;
use Paston\VerBundle\Entity\TimeZone;
use Doctrine\Common\Persistence\ObjectManager;

class LoadTimeZoneData 
    implements FixtureInterface {

    function load(ObjectManager $manager) {

        $z = new \TimeZone();
        $z->setName('Timezone');
        $manager->persist($z);
        $manager->flush();
    }

}
