Description:
------------
I wasn't able to use array_slice or array_splice on my associative arrays so I wrote two functions that others may find useful.

Reproduce code:
---------------
/* Remove a list of Associative keys 
from an array
*/
function array_unset(&$array,$list) {
  foreach($list as $val) {
    unset($array[$val]);
  }
}  

/* Transport a list of Associate keys 
from one array to another
*/
function array_trans(&$arrayfrom,&$arrayto,$list) {
  foreach ($list as $val) {
    $arrayto[$val]=$arrayfrom[$val];
    unset($arrayfrom[$val]);
  }
}
