如何使用 PHP 检索多维数组的特定元素

Question

I am building a homelab dashboard using php and html. Currently I am attempting to take information from an array and display it within a div. The information provided in the array is the url for an iframe as well as height and width adjustements. My question is how would I retrieve specific elements of this array so I can display it correctly.

$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

Lets say you want to access the url. You can do this by doing

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

etc.

You can also use a loop.

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

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