关联数组和格式问题

Question

I've been attempting to create a dashboard with grafana embedded graphs. I've had some problems with formatting them which I believed was something I was coding incorrectly but after investigating and creating a different post about it here I've confirmed that this should and does output correctly all of my dashlets. My problem is that it is not displaying them, instead its only displaying the first one inside the array.

My code:

/*

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

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

My output:

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

Check modified foreach loop:

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";
}
