array_push 到一个现有的键

Question

So I have been trying to push an array into an array, but it ends up creating it seperately. Not really sure how to phrase it, but below is the php code:

function build_embed() {

    $output = array(
        "username" => "Form Username",
        "description" => "Form Description",
        "tts" => false,
        "embeds" => [
            [
                "title" => "Form Title",
                "type" => "rich",
                "fields" => []
            ]
        ]
    );

    foreach ( $this->inputs as $val ) :

        $id = $val['id'];
        $label = $val['label'];

        $newfields = [
            "name" => $label,
            "value" => $id,
            "inline" => false
        ];

        array_push($output['embeds']['fields'], $newfields);

    endforeach;

    return $output;
}

Output of the array:

array(4) { 
    ["username"]=> string(13) "Form Username" 
    ["description"]=> string(16) "Form Description" 
    ["tts"]=> bool(false) 
    ["embeds"]=> array(2) { 
        [0]=> array(3) { 
            ["title"]=> string(10) "Form Title" 
            ["type"]=> string(4) "rich" 
            ["fields"]=> array(0) { } 
        } 
        ["fields"]=> NULL 
    } 
}

Should be like:

array(4) { 
    ["username"]=> string(13) "Form Username" 
    ["description"]=> string(16) "Form Description" 
    ["tts"]=> bool(false) 
    ["embeds"]=> array(2) { 
        [0]=> array(3) { 
            ["title"]=> string(10) "Form Title" 
            ["type"]=> string(4) "rich" 
            ["fields"]=> array("name" => "Test","value" => "Test","inline" => false) { } 
        } 
    }

You have defined embeds as a multidimensional array with one element array ( see the array structure here ), so you would push onto the first element of embeds which is 0 and then fields :

array_push($output['embeds'][0]['fields'], $newfields);

However this is the more common and practical way:

$output['embeds'][0]['fields'][] = $newfields;

If it were defined like this, it would work with the current code:

    "embeds" => [
            "title" => "Form Title",
            "type" => "rich",
            "fields" => []
    ]

Or:

$output['embeds']['fields'][] = $newfields;
