Php 无法从zf3中的ResultSet对象数组中获取数据

我正在使用zend framework3和数据库的Mysql驱动程序。 我正在使用以下代码获取数据：

        $con = $this->adapter;
        $select = $this->sql->select();
        $select->from('nav_menu');
        $selectString = $this->sql->getSqlStringForSqlObject($select);
        $results = $con->query($selectString, $con::QUERY_MODE_EXECUTE);
        $resultSet = new ResultSet();
        $resultSet->initialize($results); 

当我var_转储此数据时，我得到的结果如下：

   Zend\Db\ResultSet\ResultSet Object
   (
    [allowedReturnTypes:protected] => Array
    (
        [0] => arrayobject
        [1] => array
    )
    [arrayObjectPrototype:protected] => ArrayObject Object
    (
        [storage:ArrayObject:private] => Array
            (
            )
        )

[returnType:protected] => arrayobject

            (

                [1] => array
            )

            (
                [storage:ArrayObject:private] => Array
                    (
                    )

            )

                        [field_count] => 8
                        [lengths] => 
                        [num_rows] => 15
                        [type] => 0
                    )

                [isBuffered:protected] => 1
                [position:protected] => 0
                [numberOfRows:protected] => -1
                [currentComplete:protected] => 
                [nextComplete:protected] => 
                [currentData:protected] => 
                [statementBindValues:protected] => Array
                    (
                        [keys] => 
                        [values] => Array
                            (
                            )

                    )

                [generatedValue:protected] => 0
            )

        [fieldCount:protected] => 8
        [position:protected] => 0
    )

[fieldCount:protected] => 
[position:protected] => 0
)

       foreach ($resultSet as $key => $value) {
            $array[$i]['id'] = $value->id;
            $array[$i]['name'] = $value->name;
            $array[$i]['label'] = $value->label;
            $array[$i]['route'] = $value->route;
            $array[$i]['parent_id'] = $value->parent_id;
            $i++;
        }

当我重复此操作以获得如下值时，我得到一个错误：

                    )

            )

        [fieldCount:protected] => 8
        [position:protected] => 0
    )

[fieldCount:protected] =>

)

       foreach ($resultSet as $key => $value) {
            $array[$i]['id'] = $value->id;
            $array[$i]['name'] = $value->name;
            $array[$i]['label'] = $value->label;
            $array[$i]['route'] = $value->route;
            $array[$i]['parent_id'] = $value->parent_id;
            $i++;
        }

我不知道我错在哪里。当有num_行时，行数为15。这在ZF2中运行良好。 感谢任何人的帮助

我尝试了很多，发现如果替换代码

    $selectString = $this->sql->getSqlStringForSqlObject($select);
    $results = $con->query($selectString, $con::QUERY_MODE_EXECUTE);

和

    $statement = $this->sql->prepareStatementForSqlObject($select);
    $results = $statement->execute(); 

然后我得到了结果。但是我的问题是为什么我没有通过测试

    $selectString = $this->sql->getSqlStringForSqlObject($select);
    $results = $con->query($selectString, $con::QUERY_MODE_EXECUTE);

getSqlStringForSqlObject

自2.4版以来已被弃用。但是我不知道这是否是它不再工作的原因

根据研究，有两种方法可以实现这一点。使用与您使用的完全相同的prepare语句：

$statement = $sql->prepareStatementForSqlObject($select);
$results = $statement->execute();

执行查询时，您可能正在查找：

$selectString = $sql->buildSqlString($select);
$results = $adapter->query($selectString, $adapter::QUERY_MODE_EXECUTE);

你知道怎么调用程序吗。我正在使用这个代码$results=$con->query（'CALL

fetching_menu

（？）'，$spParams）；$resultSet=新结果集；$resultSet->initialize（$results）；其中$spParams=array（'backend'）；我出错了，我解决了这个问题。我使用$spParams=['backend']；$statement=$con->createStatement（'CALL

fetching_menu

（？）'，$spParams）；$result=$statement->execute（）；$resultSet=新结果集；$resultSet->initialize（$result）；
