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
)
)
