Question

我有一个使用Symfony用PHP编写的Web应用程序，我将它从本地计算机移动到远程服务器。当我尝试登录时出现错误：

致命错误：AdminUserRole :: getAccessibleEmployeeIds（）的声明必须与AbstractUserRole :: getAccessibleEmployeeIds（）的声明兼容

AdminUserRole类

class AdminUserRole extends AbstractUserRole {

public function getAccessibleEmployeeIds($operation = null, $returnType = null, $requiredPermissions = array()) {

    return $this->getEmployeeService()->getEmployeeIdList(false);
}

public function getAccessibleEmployeePropertyList($properties, $orderField, $orderBy, $requiredPermissions = array()) {

    return $this->getEmployeeService()->getEmployeePropertyList($properties, $orderField, $orderBy, false);
}

public function getAccessibleEmployees($operation = null, $returnType = null, $requiredPermissions = array()) {

    $employees = $this->getEmployeeService()->getEmployeeList('empNumber', 'ASC', true);

    $employeesWithIds = array();

    foreach ($employees as $employee) {
        $employeesWithIds[$employee->getEmpNumber()] = $employee;
    }

    return $employeesWithIds;
}

public function getAccessibleLocationIds($operation, $returnType) {

    $locations = $this->getLocationService()->getLocationList();

    $ids = array();

    foreach ($locations as $location) {
        $ids[] = $location->getId();
    }

    return $ids;
}

public function getAccessibleOperationalCountryIds($operation, $returnType) {

    $operationalCountries = $this->getOperationalCountryService()->getOperationalCountryList();

    $ids = array();

    foreach ($operationalCountries as $country) {
        $ids[] = $country->getId();
    }

    return $ids;
}

public function getAccessibleSystemUserIds($operation, $returnType) {

    return $this->getSystemUserService()->getSystemUserIdList();
}

public function getAccessibleUserRoleIds($operation, $returnType) {

    $userRoles = $this->getSystemUserService()->getAssignableUserRoles();

    $ids = array();

    foreach ($userRoles as $role) {
        $ids[] = $role->getId();
    }

    return $ids;
}

}

我的抽象类

abstract class AbstractUserRole {

public function setEmployeeService($employeeService) {
    $this->employeeService = $employeeService;

        $this->locationService = new LocationService();
    }
    return $this->locationService;

    $this->locationService = $locationService;
}

    }
    return $this->operationalCountryService;

public function getAccessibleEntities($entityType, $operation = null, $returnType = null, $requiredPermissions = array()) {

    switch ($entityType) {

            $entities = $this->getAccessibleEmployees($operation, $returnType, $requiredPermissions);
            break;
    }
    return $entities;
}

public function getAccessibleEntityProperties($entityType, $properties = array(), $orderField = null, $orderBy = null, $requiredPermissions = array()) {

    switch ($entityType) {
        case 'Employee':

        case 'OperationalCountry':
            $ids = $this->getAccessibleOperationalCountryIds($operation, $returnType);
            break;
        case 'UserRole':

public abstract function getAccessibleEmployeeIds($operation, $returnType, $requiredPermissions = array());

public abstract function getAccessibleOperationalCountryIds($operation, $returnType);

public abstract function getAccessibleUserRoleIds($operation, $returnType);

public abstract function getAccessibleLocationIds($operation, $returnType);

}

Answer 1

嗯，这两个功能签名不兼容。

abstract public function getAccessibleEmployeeIds($operation, $returnType, $requiredPermissions = array());
         public function getAccessibleEmployeeIds($operation = null, $returnType = null, $requiredPermissions = array()) {

abstract函数至少需要两个参数，而您的实现可以不带参数调用。这不是同一个签名。删除null默认值。

Answer 2

您的方法声明是

public abstract function getAccessibleEmployeeIds($operation, $returnType, $requiredPermissions = array());

但实际的实现是

public function getAccessibleEmployeeIds($operation = null, $returnType = null, $requiredPermissions = array());

如您所见，原始声明至少需要2个参数，但您的实现突然说不需要任何参数。

您可能在服务器上使用PHP启用了严格模式，或者只安装了更严格规则集的新版本，这使得实现与声明完全相同。

只需将AdminUserRole.php中的代码更改为

即可

public function getAccessibleEmployeeIds($operation, $returnType, $requiredPermissions = array())
{
    return $this->getEmployeeService()->getEmployeeIdList(false);
}

你会没事的。
