How to extract data from multi dimentional array

Hi,

Please help me to extract certain contents from a multi dimensional array:

var_dump($data); //now below is what this is var dumping

array (size=1)
  'multi_select' =>
    array (size=2)
      'user_value' =>
        array (size=2)
          0 => string 'US' (length=2)
          1 => string 'VI' (length=2)
      'config' =>
        array (size=14)
          'section' => string 'no' (length=2)
          'sectitle' => string '' (length=0)
          'id' => string 'multi_select' (length=12)
          'label' => string 'Multi Select' (length=12)
          'type' => string 'selects' (length=7)
          'deflt' => string '' (length=0)
          'options' => string 'US|United States
CA|Canada
VI|Virgin Islands (U.S.)' (length=51)
          'expected' => string '' (length=0)
          'required' => string 'yes' (length=3)
          'levels' => string 'all' (length=3)
          'editable' => string 'yes' (length=3)
          'classes' => string '' (length=0)
          'styles' => string '' (length=0)
          'attrs' => string '' (length=0)

Now I want to extract only the US and VI from these (and if anything extra, them also):

0 => string 'US' (length=2)
1 => string 'VI' (length=2)

Please help me

Thanks in advance
