关联数组和格式的问题

Question

我一直在尝试使用 grafana 嵌入式图表创建仪表板。我在格式化它们时遇到了一些问题，我认为这是我编码不正确的问题，但是在调查并在这里创建了一篇关于它的不同帖子之后，我已经确认这应该并且确实正确输出了我的所有 dashlets。我的问题是它没有显示它们，而是只显示数组中的第一个。

我的代码：

$dl = array
(
    'dashlet1' => array(
        'url' => 'http://192.168.86.105:3000/dashboard-solo/db/home?panelId=6',
        'height' => '200',
        'width' => '450'
    ),
    'dashlet2' => array(
        'url' => 'http://192.168.86.105:3000/dashboard-solo/db/home?panelId=7',
        'height' => '200',
        'width' => '450'
    ),
    'dashlet3' => array(
        'url' => 'http://192.168.86.105:3000/dashboard-solo/db/home?panelId=11',
        'height' => '200',
        'width' => '450'
    ),
    'dashlet4' => array(
        'url' => 'http://192.168.86.105:3000/dashboard-solo/db/home?panelId=4',
        'height' => '200',
        'width' => '350'
    ),
    'dashlet5' => array(
        'url' => 'http://192.168.86.105:3000/dashboard-solo/db/home?panelId=8',
        'height' => '200',
        'width' => '450'
    ),
    'dashlet6' => array(
        'url' => 'http://192.168.86.105:3000/dashboard-solo/db/home?panelId=10',
        'height' => '200',
        'width' => '450'
    ),
    'dashlet7' => array(
        'url' => 'http://192.168.86.105:3000/dashboard-solo/db/home?panelId=3',
        'height' => '200',
        'width' => '450'
    ),
    'dashlet8' => array(
        'url' => 'http://192.168.86.105:3000/dashboard-solo/db/home?panelId=5',
        'height' => '200',
        'width' => '350'
    )
);
foreach ($dl as $element) {
    $url = $element["url"];
    $height = $element["height"];
    $width = $element["width"];

    echo "<iframe src=\"" . $url . "\"" . " height=\"" . $height . "\" " . "width=\"" . $width . "\"" . " frameborder=\"0\">" . " " . "<\iframe>" . "\n";

我的输出：

<iframe src="http://192.168.86.105:3000/dashboard-solo/db/home?panelId=6" height="200" width="450" frameborder="0"> &lt;\iframe&gt;

检查修改后的foreach循环：

foreach ($dl as $element) {
    $url = $element["url"];
    $height = $element["height"];
    $width = $element["width"];

    echo "<iframe src=\"{$url}\" height=\"{$height}\" width=\"{$width}\" frameborder=\"0\"></iframe>\n";
}
