Old version (v0.1): 

function TrimArray($arr){
  if (!is_array($arr)){ return $arr; }

  while (list($key, $value) = each($arr)){
    if (is_array($value)){
      $arr[$key] = TrimArray($value);
    }
    else {
      $arr[$key] = trim($value);
    }
  }
  return $arr;
}

//演示范例：
$DirtyArray = array(
  'Key1' => ' Value 1 ',
  'Key2' => '   Value 2   ',
  'Key3' => array(
    '  Child Array Item 1 ', 
    '  Child Array Item 2'
  )
);

$CleanArray = TrimArray($DirtyArray);

var_dump($CleanArray);

/*
Result will be:

array(3) {
 ["Key1"]=>
 string(7)"Value 1"
 ["Key2"]=>
 string(7)"Value 2"
 ["Key3"]=>
 array(2) {
  [0]=>
  string(18)"Child Array Item 1"
  [1]=>
  string(18)"Child Array Item 2"
 }
}
