PHP：回显多维数组

Question

我有一个这样的数组输出：

Array
(
    [2015-01-23] => Array
        (
            [0] => Array
                (
                    [orgdate] => 2015-01-23
                    [origin] => india
                )

        [1] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => us
            )

        [2] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => england
            )

        [3] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => india2
            )

        [4] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => uae
            )

        [5] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => africa
            )

        [6] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => china
            )

        [7] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => hongkong
            )

        [8] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => africa2
            )

        [9] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => africa3
            )

        [10] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => africa4
            )

        [11] => Array
            (
                [orgdate] => 2015-01-23
                [origin] => africa5 
            )

    )

[2015-01-14] => Array
    (
        [0] => Array
            (
                [orgdate] => 2015-01-14
                [origin] => japan1
            )

        [1] => Array
            (
                [orgdate] => 2015-01-14
                [origin] => japan2
            )

        [2] => Array
            (
                [orgdate] => 2015-01-14
                [origin] => japan3
            )

        [3] => Array
            (
                [orgdate] => 2015-01-14
                [origin] => japan4
            )

    )

[2015-01-13] => Array
    (
        [0] => Array
            (
                [orgdate] => 2015-01-13
                [origin] => russia
            )

    )

)

现在我想显示 2015-01-23 , 2015-01-14 , 2015-01-13 然后是每个内部内容

origin: india
origin: usa
origin: england , etc....

我如何做到这一点。？我已经尝试过像 this 这样的递归函数，但这找不到解决方案

任何帮助将不胜感激

Answer 1

你不需要递归，因为你的数组是平的（只有 1 深）

我不确定你想要什么，但是：

foreach($array as $key=>$subarray)
{
    echo $key;
    foreach($array[$key] as $subarray)
    {
        echo "origin".$subarray["origin"];
    }
}

这应该可以。 如果您只想查看调试，请使用 var_dump($array);

Answer 2

试试这个：

foreach($array as $innerArray){
 foreach($innerArray as $result){
echo "origin: "." ".$result['orgdate']." ".$result['origin'];
 }
}
