note 102564 added to function.array-key-exists

@tech at signhere envy dot de

There is a much more straight forward way of renaming an array, like this example:

<?php

function array_rename_key($array, $key, $newkey)
{
    if( ! array_key_exists($key, $array) || array_key_exists($newkey, $array) )
            return FALSE;

    $array[$newkey] = $array[$key];
    unset($array[$key]);

    return $array;
}

?>
