you probably meant to define it as:
$my_array = array('bob' => $x, 'jim' => $y, 'mike' => $z);
use print_r($my_array) to see the difference between your definition and mine.

Depends on whether you want to find the name of the 'n-th' element, or the
name of the element whose value is '$y'.
If the former you can use array_slice(), the latter key().
