How do I move an array element with a known key to the end of an array in PHP?

Question

Having a brain freeze over a fairly trivial problem. If I start with an array like this:

$my_array = array(
                  \'monkey\'  => array(...),

You can implement some basic calculus and get a universal function for moving array element from one position to the other.

For PHP it looks like this:

function magicFunction ($targetArray, $indexFrom, $indexTo) { 
    $targetElement = $targetArray[$indexFrom]; 
    $magicIncrement = ($indexTo - $indexFrom) / abs ($indexTo - $indexFrom); 

    for ($Element = $indexFrom; $Element != $indexTo; $Element += $magicIncrement){ 
        $targetArray[$Element] = $targetArray[$Element + $magicIncrement]; 
    } 

    $targetArray[$indexTo] = $targetElement; 
}
