如何在php中将数组格式化为具有新索引的数组

我试图格式化我的代码，如下所示。但没有做到这一点

我的标准和代码如下所述

以下是我的数组结构：

    Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [tagged_field] => description
                    [created_date] => 2015-02-06 14:47:44
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [tagged_field] => description_html
                    [created_date] => 2015-02-06 14:47:44
                )

            [1] => Array
                (
                    [tagged_field] => description_html
                    [created_date] => 2015-02-06 14:47:44
                )

        )

)

Array
(
    [0] => Array
        (
            [tagged_field] => description
            [created_date] => 2015-02-06 14:47:44
        )

    [1] => Array
        (
            [tagged_field] => description_html
            [created_date] => 2015-02-06 14:47:44
        )
[2] => Array
        (
            [tagged_field] => description_html
            [created_date] => 2015-02-06 14:47:44
        )
)

所需的阵列结构：

    Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [tagged_field] => description
                    [created_date] => 2015-02-06 14:47:44
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [tagged_field] => description_html
                    [created_date] => 2015-02-06 14:47:44
                )

            [1] => Array
                (
                    [tagged_field] => description_html
                    [created_date] => 2015-02-06 14:47:44
                )

        )

)

Array
(
    [0] => Array
        (
            [tagged_field] => description
            [created_date] => 2015-02-06 14:47:44
        )

    [1] => Array
        (
            [tagged_field] => description_html
            [created_date] => 2015-02-06 14:47:44
        )
[2] => Array
        (
            [tagged_field] => description_html
            [created_date] => 2015-02-06 14:47:44
        )
)

我的代码：

foreach($tagArr as $key => $value){
            $a_tag[$inc] = $value[0];
            $inc++;
        }

但无法像那样格式化数组

如果我的输入数组如上所述，如何按所需格式对数组进行排序。

请尝试-

foreach($tagArr as $key => $value){
    foreach($value as $val) {
            $a_tag[] = $val;
    }
}

用这个

$a_tag = [];
foreach ($tagArr as $value) {
     $a_tag += $value;
}

您可以使用以下代码执行此操作：

foreach($tagArr as $key => $value){
    foreach($value as $val) {
          $a_tag[] = $val;
    }
}

但您不必使用$inc++；anymore@RaphaelM谢谢你指出这一点。更新了答案。@user3797205如果键相同，则可以避免第二个循环。不能使用数组_值，它会破坏像标记_字段一样的索引
