                @endforeach
            </div>

I am generating these objects to manage a set of keys in a sector.

Can someone help me find a way to do this code.

So you left the key chave_usuario_responsavel in foreach, this gets executed in else condition — Thamilhan

Yes, you've nested arrays, but htmlspecialchars expects string.

Below a recursive array_map from https://gist.github.com/igorw/7628042 which makes it possible to apply htmlspecialchars to a nested array.

function array_map_recursive($f, $xs) {
    $out = [];
    foreach ($xs as $k => $x) {
        $out[$k] = (is_array($x)) ? array_map_recursive($f, $x) : $f($x);
    }
    return $out;
}

$data = [
    'foo' => [
        'bar' => [
            'baz' => [
                'lorem ipsum'
            ]
        ]
    ]
];

print_r(array_map_recursive('htmlspecialchars', $data));

I did not understand how to apply in my situation. Could you please explain how to apply with this array on my blade.

schellingerht Over a year ago

Ok, you can fill $data with your array. I suppose it's better to do this in your controller method before passing the array to your blade view.

Gladson Over a year ago

The way it is, I get one object at a time. php @elseif (in_array($key_obj == 'numero_chave', $value)) {{ $value_obj }}@endif return "13"

Gladson Over a year ago

I want to access the other objects. "users_responsavel_nome" => "Freitas" || "users_responsavel_cgu_cpf" => "1185420"
