Cannot get array key name

I'm trying to get the array key name of the following:

[tax_input] => Array
(
    [property-category] => Array
        (
            [1] => 4
            [2] => 8
        )

    [property-action] => Array
        (
            [1] => 9
        )
)

so I'm iterating it as:

foreach($tax_input as $key => $tax)
{
    var_dump($tax_input[$key]);
}

but this return an empty string, what I did wrong?

You should just echo $key instead of $tax_input[$key]

If you want to get key only then use 

foreach($tax_input as $key => $tax)
{
  var_dump($key);
}

try this one.

foreach($tax_input as $k => $v)
{
    foreach( $v as $vk => $vv ){

      var_dump( '<pre>',$vv );
    }  
}
