[RESOLVED] Multidimensional Array Keys

[Bushman]

Given this multidimensional array:

$array = array (
  entry1 => array(
    foo => junk
    bar => 14
    )
  entry2 => array (
    foo => nonjunk
    bar => 7
  )
)
/*Every array with a numeric key has the same set of associative keys*/

How is it possible to get the value of every "foo" key OR every "bar" key, irrespective of the size of the array?

foreach ($array as $entry) {
	// either do another foreach here, or access the elements directly
	$entry['foo']
}
