how to manipulate this array ??

[PHPycho]

Hello forums !!
Case:
I had the array as:

$array = array(1 => array('key1' => 'xxx', 'status' => 'Y'), 2 => array('key1' => 'yyy', 'status' => 'N'), 3 => array('key1' => 'zzz', 'status' => 'N')...); 

I would like to find the next and previous key in the array according to the status. ie

function getNextKey(){
    //should return the 2 as 1 key has status Y (Yes)
    // if 1 key has status 'N' then it should return 1 key
}
function getCurrentKey(){
    // should return 1
    // if 2 key too had status 'Y' then it should return 2
}
function getPrevkey(){
    // should return null
    // if 2 key too had status 'Y' then it should return 1
} 

How to accomplish this type of array manipulation??
Thanks in advance for the valueable help.
