Laravel - can't get values from multidimensional array with blade

I am having trouble looping through a multidimensional array with blade in laravel. I am sending the data from the controller like so: 

return View::make('store.categories')
            ->with('brands', $brands);

And if I die dump the data:

array (size=2)
  0 => 
    array (size=2)
      0 => string 'Fender' (length=6)
      1 => string '(2)' (length=3)
  1 => 
    array (size=2)
      0 => string 'Gibson' (length=6)
      1 => string '(1)' (length=3)

I've tried to use two @foreach loops but I couldn't get it to work: 

@foreach($brands as $brand)
  @foreach($brand as $b)
  {{$b}}
  @endforeach
@endforeach

The above will output: Fender (2) Gibson (1).

I tried to get the 0 value for the $b to output Fender but it just prints the 0 position character for each of the items in the $b array: 

@foreach($brands as $brand)
  @foreach($brand as $b)
  {{$b[0]}}
  @endforeach    
@endforeach

The above will output F ( G (.

In my controller if I do: 

foreach ($brands as $b) {
    foreach($b as $key=>$v) {
       dd($v);
    }
}

it will output string 'Fender' (length=6), which seems like the second loop inside the first @foreach works. Although, when it comes to the blade code mentioned above it doesn't.

I'm probably doing something terribly wrong. How can I get the output for the values 0 and 1 for the nested arrays individually? Any help is highly appreciated.

This is how I create the data in my controller's function: 

$products = Product::with('brand')->whereIn('category_id', $children->lists('id'));
$brand_ids = array();
$brands = array();

foreach ($products->get() as $p) {
    $brand_ids[] = $p->brand_id;
}
$brand_count = array_count_values($brand_ids); 
foreach ($brand_count as $key=>$value) {
    $query = Brand::where('id', '=', $key)->lists('name');
    // dd($query);
    foreach($query as $key=>$name) {
        $array = array(
             $name,
             '('.$value.')'
            );
        $brands[] = $array;
    }
}

as you want to get the 2nd level values of multi dimensional array, and if you know that 2nd level will have only two values, then why don't you try

@foreach($brands as $brand) 
    {{$brand[0]}} {{$brand[1]}}
@endforeach

Controller

$brands = Brand::whereIn('id', $brand_ids)->lists('name', 'id');

Blade

@foreach($brands as $id => $brand)
    Id: {{$id}}, Brand: {{$brand}}
@endforeach

This should work and save you performance, cause we query all the brands instead of each one individually. A better approach would be to have the products relation set up and get them that way.

@foreach($brands as $brand)
  {{$brand[0]}}
@endforeach

You need to look at how the array is organized. Once you dig into the first level, 'Fender' is at offset [0] and '(2)' is at offset [1], so you only need one foreach.

The reason you were getting F is because you were getting the offset [0] on the string 'Fender' (or in other words, the first letter) because the second foreach was bringing you four strings, not arrays.

$brands = [
  0 => 
    [
      0 => 'Fender',
      1 => '(2)'
    ],
  1 => 
    [
      0 => 'Gibson',
      1 => '(1)'
    ]
];

var_dump($brands);

foreach($brands as $brand) {
  echo $brand[0]."\n";
}

Outputs:

array(2) {
  [0]=>
  array(2) {
    [0]=>
    string(6) "Fender"
    [1]=>
    string(3) "(2)"
  }
  [1]=>
  array(2) {
    [0]=>
    string(6) "Gibson"
    [1]=>
    string(3) "(1)"
  }
}
Fender
Gibson
