对象数组中的对象数组

Question

我想将一个名为子分支的对象数组发送到相同对象的主数组中。

从同一张桌子上

我有一个包含主分支和子分支的表，我需要在主对象中的数组中添加子数据，这个数组应该被调用(SubBranches)

如何获得这个JSON：

我是如何使用php i用户获得相同的json的，这个函数就像我的putit一样得到json smae。

function action_getall2(){
    global $db;
    global $table_name;
    $all = $db->get($table_name);
    $data=array();
    // $data2 = array();

    $pcnt=0;
    $ccnt=0;

    for($i=0;$i<count($all);$i++){

        if($all[$i]['ParentID']==0){
            $data[$pcnt]=$all[$i];

            for($j=0;$j<count($all);$j++){
                if($all[$j]['ParentID'] == $all[$i]['ServiceTypeID']){
                    $data[$pcnt][$ccnt]=$all[$j];
                    $ccnt++;        
                }
            }
            $ccnt=0;
            $pcnt++;
        }

    }
    echo json_encode($data2);
    exit;
}

Answer 1

这里是您的解决方案，用以下代码修改代码。

$data=array();
$all  = array(
        array('ServiceTypeID'=>1,'ParentID'=>'0','type'=>'abc'),
        array('ServiceTypeID'=>2,'ParentID'=>'0','type'=>'xyz'),
        array('ServiceTypeID'=>3,'ParentID'=>'2','type'=>'abs'),
        array('ServiceTypeID'=>6,'ParentID'=>'1','type'=>'bas'),
        array('ServiceTypeID'=>8,'ParentID'=>'2','type'=>'ddd')
    );

foreach($all as $key => $val)
{
    if($val['ParentID']==0)
    {
        $data[$key]=$val;

        foreach($all as $k => $v)
        { 
            if($val['ServiceTypeID'] == $v['ParentID']){
                $data[$key]['subBranches'][]= $v;
            }
        }
    }
}
echo "<pre>"; print_r($data);

这将产生以下结果：

Array
(
    [0] => Array
        (
            [ServiceTypeID] => 1
            [ParentID] => 0
            [type] => abc
            [subBranches] => Array
                (
                    [0] => Array
                        (
                            [ServiceTypeID] => 6
                            [ParentID] => 1
                            [type] => bas
                        )

                )

        )

    [1] => Array
        (
            [ServiceTypeID] => 2
            [ParentID] => 0
            [type] => xyz
            [subBranches] => Array
                (
                    [0] => Array
                        (
                            [ServiceTypeID] => 3
                            [ParentID] => 2
                            [type] => abs
                        )

                    [1] => Array
                        (
                            [ServiceTypeID] => 8
                            [ParentID] => 2
                            [type] => ddd
                        )

                )

        )

)

这里我已经有了print_r数据数组，如果需要的话，可以json_encode($data);。

Answer 2

$array = array( array(), array(), ...);
$json = json_encode($array);
echo $json

编辑:

$array = array();
for ($i=0; $i < 5; $i++) { 
    array_push($array, array('iteration' => $i));
}
$json  = json_encode($array);
echo $json;

输出是

{“迭代”：0}，{“迭代”：1}，{“迭代”：2}，{“迭代”：3}，{“迭代”：4}

或

[
    {
        "iteration":0
    },
    {
        "iteration":1
    },
    {
        "iteration":2
    },
    {
        "iteration":3
    },
    {
        "iteration":
    }
]

这不是你想要的吗？
