关于循环数组合并的有关问题

关于循环数组合并的问题
foreach ($keyword as $val){

  $sql="Select title from XXXX title like '%$val%' limit 10 ";
  $list = array();
  $dsql->SetQuery($sql);
  $dsql->Execute();
  while ($row = $dsql->GetArray()) {
  $list[] = $row;
  }
}
结果是这样的。 请问怎么合并 并去除重复。。  
Array
(
  [0] => Array
  (
  [title] => 1111111111
  )

  [1] => Array
  (
  [title] => 22222222222
  )

  [2] => Array
  (
  [title] =>333333333333
  )
)
Array
(
  [0] => Array
  (
  [title] => 1111111111
  )
)
