php -不能用作同名函数的别名

Question

我得到以下错误“使用.作为.”语法

Fatal error: An alias was defined for method getRoles(), which exists in both MembersBundle\Adapter\User\UserTrait and FrontendPermissionToolkitBundle\CoreExtensions\Traits\PermissionResourcesAsRolesTrait. Use MembersBundle\Adapter\User\UserTrait::getRoles or FrontendPermissionToolkitBundle\CoreExtensions\Traits\PermissionResourcesAsRolesTrait::getRoles to resolve the ambiguity in **/Model/DataObject/CombinedUserAndCustomer.php on line 17

以下是文件：

<?php

declare(strict_types=1);

namespace CosmicCoreBundle\Model\DataObject;

use CoreShop\Component\Core\Model\Customer;
use FrontendPermissionToolkitBundle\CoreExtensions\Traits\PermissionResourcesAsRolesTrait;
use MembersBundle\Adapter\User\UserInterface;
use MembersBundle\Adapter\User\UserTrait;
use CustomerManagementFrameworkBundle\Model\CustomerInterface;
use CustomerManagementFrameworkBundle\Model\Traits\CustomerTrait;

/**
 * Combines the members user with the CoreShop customer
 */
abstract class CombinedUserAndCustomer extends Customer implements UserInterface, CustomerInterface
{
    use UserTrait {
        getRoles as getMembersRoles;
    }

    use PermissionResourcesAsRolesTrait {
        getRoles as getPermissionResourceRoles;
    }

    use CustomerTrait;

    /**
     * Retrieve all allowed permission resources of current object prefixed with ROLE_
     *
     * @return string[]
     */
    public function getRoles(): array
    {
        // Combine CoreShop roles with members and permission resource roles
        return array_merge(
            parent::getRoles(),
            $this->getMembersRoles(),
            $this->getPermissionResourceRoles()
        );
    }
}

它安装在pimcore中(symfony 5框架)，我使用php8.1，如果有人能解释问题所在，我会很高兴的。谢谢^^

除了@MEriksson注释之外，您还必须像这样重写代码，以避免函数名称冲突。就像这样：

抽象示例代码

<?php

trait UserTrait {
    public function getRoles() {
        echo 'roleFromUserTrait';
    }

    public function make1() {
        echo 'A';
    }
}

trait PermissionResourcesAsRolesTrait {
    public function getRoles() {
        echo 'roleFromPermissionResourcesAsRolesTrait';
    }
    public function make2() {
        echo 'B';
    }
}

class Hello {
    use UserTrait, PermissionResourcesAsRolesTrait {
        UserTrait::getRoles insteadof PermissionResourcesAsRolesTrait;
        UserTrait::getRoles as getR1;
        PermissionResourcesAsRolesTrait::getRoles insteadof UserTrait;
        PermissionResourcesAsRolesTrait::getRoles as getR2;        
    }
}

$h = new Hello();
print_r($h->getR1());
print_r($h->getR2());
