Printing the keys of array elements which are arrays

Question

I have this array:

 <?php
    $arr = array('submitted',
                 'region' => array('value 1','value2','value3'),
                 'sended',
                 'something' => array('value','value'));

  ?>

The question is how to check if an element is an array and print the corresponding key.

The output should be:

region  something

i dont understand what do you want exactly, please describe it better — rsz
