Question

我有一个数组，我想从中删除第一级索引并保留它的值是否有可能没有循环？

输入数组：

Array (
    [0] => Array(
             [2135] => Array(
                         [id] => 2135
                         [first_name] => John
                         [last_name] => Doe
                       )
            ),
    [1] => Array (
             [3245] => Array(
                         [id] => 3245
                         [first_name] => Sally
                         [last_name] => Smith
                       )
            )
)

预期输出：

Array (
     [2135] => Array(
                 [id] => 2135
                 [first_name] => John
                 [last_name] => Doe
               ),


     [3245] => Array(
                 [id] => 3245
                 [first_name] => Sally
                 [last_name] => Smith
               )
)

Answer 1

试试这个

$a = array (
    array(
        '2135' => array(
            'id' => 2135,
            'first_name' => 'John',
            'last_name' => 'Doe'
        )
    ),
    array (
        '3245' => array(
            'id' => 3245,
            'first_name' => 'Sally',
            'last_name' => 'Smith',
        )
    )
);
$reduce = function ($new = array(), $x) {
    $new[array_keys($x)[0]]=array_values($x)[0];
    return $new;
};

$output = array_reduce($a, $reduce);

// var_dump($output);

Answer 2

简短（评论）回答：

shp.type

<强>输出：

Sub nameTheShapes()
    Dim shp As Shape
    For Each shp In Sheet1.Shapes
        If shp.type = 1 Then
            shp.TextFrame2.TextRange.Characters.Text = shp.ID
        End If
    Next
End Sub

Answer 3

没有循环会很困难，但是可能的解决办法是：

$file_array = array();
foreach($array_name as $row =>$value){
    foreach ($value as $row1 =>$value1){
        if(in_array($value1, $file_array)){
        }
        else{
        $file_array[] =$value1;
        }
    }
}

从数组php中删除第一级索引
