Question

我正在使用php和html构建一个homelab仪表板。目前我正在尝试从数组中获取信息并将其显示在div中。数组中提供的信息是iframe的url以及高度和宽度调整。我的问题是如何检索此数组的特定元素，以便我可以正确显示它。

$dl = [
    'dashlet1' => [
        'url' => 'some random url',
        'height' => 'height=200',
        'width' => 'width=450'
    ],
    'dashlet2' => [
        'url' => 'another random url',
        'height' => 'height=200',
        "width" => 'width=450'
    ],
    'dashlet3' => [
        'url' => 'another random url',
        'height' => 'height=200',
        'width' => 'width=450'
    ],
    'dashlet4' => [
        'url' => 'another random url',
        'height' => 'height=200',
        'width' => 'width=350'
    ],
    'dashlet5' => [
        'url' => 'another random url',
        'height' => 'height=200',
        'width' => 'width=450'
    ],
    'dashlet6' => [
        'url' => 'another random url',
        'height' => 'height=200',
        'width' => 'width=450'
    ],
    'dashlet7' => [
        'url' => 'another random url',
        'height' => 'height=200',
        'width' => 'width=350'
    ],
    'dashlet8' =>[
        'url' => 'another random url',
        'height' => 'height=200',
        'width' => 'width=450'
    ]

];

Answer 1

假设您要访问该网址。你可以通过

来做到这一点

echo $dl['dashlet1']['url'];
echo $dl['dashlet2']['url'];

等。

您也可以使用循环。

    foreach( $dl as $key => $value ) {

        echo($key . " " . $value['url']);
    }
