PHP警告：偏移量类型非法

我正在尝试启动此数组，并且一直保持该非法偏移量类型。老实说，我什至不确定我是否正确设置了阵列，任何帮助都将是一件好事！

$device_changes = array
(
    [0] => array
        (
            ['device'] => "Connect",
            ['added'] => 0,
            ['removed'] => 0,
            ['net_change'] => 0,
            ['percent_added'] => 0,
            ['percent_removed'] => 0,
        ),
    [1] => array
        (
            ['device'] => "Camera",
            ['added'] => 0,
            ['removed'] => 0,
            ['net_change'] => 0,
            ['percent_added'] => 0,
            ['percent_removed'] => 0,
        ),
    [2] => array
        (
            ['device'] => "BATlte",
            ['added'] => 0,
            ['removed'] => 0,
            ['net_change'] => 0,
            ['percent_added'] => 0,
            ['percent_removed'] => 0,
        ),
    [3] => array
        (
            ['device'] => "BATwifi";
            ['added'] => 0,
            ['removed'] => 0,
            ['net_change'] => 0,
            ['percent_added'] => 0,
            ['percent_removed'] => 0,
        ),
);

按键不需要在方括号内

所以您应该拥有：

$device_changes = array
    (
        0 => array
            (
                'device' => "Connect",
                'added' => 0,
                'removed' => 0,
                'net_change' => 0,
                'percent_added' => 0,
                'percent_removed' => 0,
            ),
        1 => array
            (
                'device' => "Camera",
                'added' => 0,
                'removed' => 0,
                'net_change' => 0,
                'percent_added' => 0,
                'percent_removed' => 0,
            ),
        2 => array
            (
                'device' => "BATlte",
                'added' => 0,
                'removed' => 0,
                'net_change' => 0,
                'percent_added' => 0,
                'percent_removed' => 0,
            ),
        3 => array
            (
                'device' => "BATwifi",
                'added' => 0,
                'removed' => 0,
                'net_change' => 0,
                'percent_added' => 0,
                'percent_removed' => 0,
            ),
    );

请注意，BATwifi后应在行尾，而不是;也是：）

编辑：

您可能对方括号感到困惑，因为可以使用array()或[]来设置数组。如：

$device_changes = [
    0 => [
        'device' => 'Connect',
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    1 => [
        'device' => 'Camera',
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    2 => [
        'device' => 'BATlte',
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    3 => [
        'device' => 'BATwifi',
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
];

您甚至可以摆脱数字键，因为默认情况下，它们将设置为您所使用的数字，从0开始并以1递增：

$device_changes = [
    [
        'device' => 'Connect',
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    [
        'device' => 'Camera',
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    [
        'device' => 'BATlte',
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    [
        'device' => 'BATwifi',
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
];

答案 1 :(得分：0)

您将printf的输出与数组的定义混合在一起。如果要定义数组，则不能使用[0]或['device']作为数组键，因为这是一个具有单个元素的数组。相反，在上面的示例中，您应该使用0或'device'。

此外，如果它只是一个自动递增编号，则可以完全跳过该键。

$device_changes = [
    [
        'device' => "Connect",
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    [
        'device' => "Camera",
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    [
        'device' => "BATlte",
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
    [
        'device' => "BATwifi";
        'added' => 0,
        'removed' => 0,
        'net_change' => 0,
        'percent_added' => 0,
        'percent_removed' => 0,
    ],
];

您可以使用我刚刚写的这个转换器“ thingy”

https://github.com/ArtisticPhoenix/MISC/tree/master/Lexers/OutputConverter

但是，如果使用print_r，则必须“撤消”所做的任何操作。即

  • 将单词*aa = 20; 大写（否则它不会检测到它的print_r）
  • 删除动词Array，'，"和,

所以看起来像这样：

;

然后它将为您提供：

Array
(
    [0] => Array
        (
            [device] => Connect
            [added] => 0
            [removed] => 0
            [net_change] => 0
            [percent_added] => 0
            [percent_removed] => 0
        )
    [1] => Array
        (
            [device] => Camera
            [added] => 0
            [removed] => 0
            [net_change] => 0
            [percent_added] => 0
            [percent_removed] => 0
        )
    [2] => Array
        (
            [device] => BATlte
            [added] => 0
            [removed] => 0
            [net_change] => 0
            [percent_added] => 0
            [percent_removed] => 0
        )
    [3] => Array
        (
            [device] => BATwifi
            [added] => 0
            [removed] => 0
            [net_change] => 0
            [percent_added] => 0
            [percent_removed] => 0
        )
)

它也可以在array ( 0 => array ( 'device' => 'Connect', 'added' => 0, 'removed' => 0, 'net_change' => 0, 'percent_added' => 0, 'percent_removed' => 0 ), 1 => array ( 'device' => 'Camera', 'added' => 0, 'removed' => 0, 'net_change' => 0, 'percent_added' => 0, 'percent_removed' => 0 ), 2 => array ( 'device' => 'BATlte', 'added' => 0, 'removed' => 0, 'net_change' => 0, 'percent_added' => 0, 'percent_removed' => 0 ), 3 => array ( 'device' => 'BATwifi', 'added' => 0, 'removed' => 0, 'net_change' => 0, 'percent_added' => 0, 'percent_removed' => 0 ) ) 上运行，并且可以检测var_dump，var_export和var_dump之间的差异。它可以处理对象，嵌套等。甚至可以像var_export ... :-D

一样缩进

我花了几天时间，因为我厌倦了不得不弄乱人们喜欢在这里发布的数组（不在var_export中）。

使用它非常容易，它具有一个带有一个按钮的Web UI和一个文本区域，可以粘贴和复制，甚至简单。

对不起，源代码太长，无法包含在帖子中，所以我喜欢它有点凌乱，但是我一直在尝试完成我的网站（在上面设置了SCSS解析器后稍作休息）。太糟糕了。

迟早我会把它放在那里，但这是一个wordpress驱动的站点，所以我可能不得不为它和所有爵士乐做一个简短的代码。

享受
