Access multidimensional array without multiple loops

Question

Let's say I have an array formatted like so:

   $data = array(
        'variables' => array(
            '823h9fhs9df38h4f8h' => array(
                'name' => 'Foo',
                'value' => 'green'
            ),
            'sdfj93248fhfhf88rh' => array(
                'name' => 'Bar',
                'value' => 'red'
            )
        )
    );

Say I wanted to access the name & values of each array in the variables array. Surely you can access it just looping over the main variables array and not looping over each individual item array? Something like so?

foreach ($data as $k => $v) {
    $name = $data['variables'][0]['name'];
}

I'm sure I'm missing something simple...

there is no $data['variables'][0], if you don't know the keys then you need to do a loop inside a loop, if you already know the keys you don't — user557846

Seeing as the key is stored in $k, why can I not use: $data['variables'][$key]['name'] — Shannon Hochkins

FYI: multiple foreach loops for a multidimensional array is very common — user557846

You can do

foreach ($data['variables'] as $k => $v) {
  $name = $v['name'];
}

You can also try this

create a new array containing just the names..

$new_arr = array_column($data['variables'],'name' );
echo $new_arr[0].'<br/>';
echo $new_arr[1].'<br/>';
