组通过一列数据组数据，并从其他列中填充每个组中的子阵列

Question

我有一个我想转换为多维数组的PHP对象，但我似乎无法解决。

这是我的数据结构...

Array (
    [0] => stdClass Object (
        [code] => 63205RMVF
        [vq_ref] => 60001689
        [start] => 2012-01-10
        [done_elm] =>
        [unitref] => D5027581
        [vqdesc] => Diploma in Dental Nursing
        [descrip] => Scientific principles in the management of oral health diseases and dental procedures
        [credit_val] => 5
        [achieve] =>
    )
    [1] => stdClass Object (
        [code] => 63205RMVF
        [vq_ref] => 60001689
        [start] => 2012-01-10
        [vq_exp] => 2014-01-09
        [enddate] =>
        [vq_act] =>
        [done_elm] =>
        [unitref] => D5027600
        [vqdesc] => Diploma in Dental Nursing (
            QCF
        )
        [bodynum] => Unit 306
        [descrip] => Provide chairside support during the assessment of patients\' oral health
        [credit_val] => 1
        [start_1] => 2013-03-19
        [expect] =>
        [achieve] => 2013-11-29
        [status] => A
        [done_elm_1] => 100
    )
    [2] => stdClass Object (
        [code] => 63205RMVF
        [vq_ref] => 60001689
        [start] => 2012-01-10
        [vq_exp] => 2014-01-09
        [enddate] =>
        [vq_act] =>
        [done_elm] =>
        [unitref] => DN317
        [vqdesc] => Diploma in Dental Nursing (
            QCF
        )
        [bodynum] => DN317
        [descrip] => Level 3 Principles and theory of Dental Nursing
        [credit_val] =>
        [start_1] =>
        [expect] =>
        [achieve] => 2013-09-19
        [status] => A
        [done_elm_1] =>
    )

我想将其转换为这样的数组模式...

[aim] = [
    [code]
    [vq_ref]
    [units] => [
        [start]
        [vq_exp]
        [enddate]
        [vq_act]
        [done_elm]
        [unitref]
        [vqdesc]
        [bodynum]
        [descrip]
        [credit_val]
        [start_1]
        [expect]
        [achieve]
        [status]
        [done_elm_1]
    ]
]

在我把这拼凑在一起的那一刻，我只是无法解决！

foreach($results as $result)
{
    $unit['aim'][$result->vq_ref]['unit'] = array()
        'unit_ref'   => $result->unitref,
        'unit_title' => $result->descrip,
        'start'      => $result->start,
        'achieved'   => $result->achieve,
        'value'      => $result->credit_val
    );
}

foreach($results as $result)
{
    $data['aim'][$result->vq_ref] = array(
        'aim_ref'   => $result->vq_ref,
        'aim_title' => $result->vqdesc,
        'units'     => array($unit['aim'][$result->vq_ref]['unit'])
    );
}

Answer 1

Get_Object_vars

$unit['aim'] = array_map('get_object_vars',$yourArray);

eDIT：对主题的误解

一种方法可以用此功能映射您的数组，并根据需要将属性分为两个集合：

function split_collection($object){
   $array = get_object_vars($object);
   $newArray = [$array['code'],$array['vqref'],"units"=>[]];
   unset($array['code']);
   unset($array['vq_ref']);
   $newArray['units'] = $array;
   return $newArray;
 }
 $unit['aim'] = array_map('split_collection',$yourCollection);

我实际上是通过使用此解决的。一开始我并不遥远，但这似乎对我来说很好...

foreach($results as $result)
{
    $units[$result->vq_ref][] = array(
        'unit_ref'   => $result->unitref,
        'unit_title' => $result->descrip,
        'start'      => $result->start,
        'achieved'   => $result->achieve,
        'value'      => $result->credit_val
    );
}

foreach($results as $result)
{
    $data['aim'][$result->vq_ref] = array(
        'aim_ref'   => $result->vq_ref,
        'aim_title' => $result->vqdesc,
        'units'     => $units[$result->vq_ref]
    );
}

Answer 2

在问答的自我撤职帖子上，可以简化此分组任务为一个循环。 为了访问数据，无需将每个对象转换为临时数组。

aim_ref

和

Answer 3

值可以自由覆盖同一组的每次迭代。 每组“单位”数据都可以推动为

units

的新孩子。 demo

$data = [];
foreach ($results as $result) {
    $data['aim'][$result->vq_ref]['aim_ref'] = $result->vq_ref;
    $data['aim'][$result->vq_ref]['aim_title'] = $result->vqdesc;
    $data['aim'][$result->vq_ref]['units'][] = [
        'unit_ref'   => $result->unitref,
        'unit_title' => $result->descrip,
        'start'      => $result->start,
        'achieved'   => $result->achieve,
        'value'      => $result->credit_val,
    ];
}
