based on worldclimb's arem(), here is a recursive array value removal tool that can work with multidimensional arrays.
function remove_from_array($array,$value){
$clear = true;
$holding=array();
foreach($array as $k => $v){
if (is_array($v)) {
$holding [$k] = remove_from_array ($v, $value);
}
elseif ($value == $v) {
$clear = false;
}
elseif($value != $v){
$holding[$k]=$v; // removes an item by combing through the array in order and saving the good stuff
}
}
if ($clear) return $holding; // only pass back the holding array if we didn't find the value
}
