PHP二维数组 去除特定重复值的有关问题

【求助】PHP二维数组 去除特定重复值的问题
原数组：
$arr = array(
array('id' => 1,'name' => 'aaa','uid'=>1),
array('id' => 2,'name' => 'bbb','uid'=>2),
array('id' => 3,'name' => 'ccc','uid'=>3),
array('id' => 4,'name' => 'ddd','uid'=>4),
array('id' => 5,'name' => 'ccc','uid'=>3),
array('id' => 6,'name' => 'bbb','uid'=>2),
array('id' => 7,'name' => 'bbb','uid'=>2),
array('id' => 8,'name' => 'fff','uid'=>6),
array('id' => 9,'name' => 'ccc','uid'=>3),
array('id' => 10,'name' => 'bbb','uid'=>2),
array('id' => 11,'name' => 'ddd','uid'=>4),
array('id' => 12,'name' => 'eee','uid'=>5),
array('id' => 13,'name' => 'fff','uid'=>6),
);

问题描叙：想获取$arr中id为 1,3,5,7,9的值，但是‘name’和‘uid’的值不能有重复。举例：id==3对应的name==ccc，但是id==5对应的 name==ccc，所以不取id为5的这一条，取它的下一条 id=6的值，如果id=6的值，和前面的还有重复，则再取下一条，以此类推。

如果想要取id为1,3,5,7,9的值，则想要的结果是：
$arr_new = array(
array('id' => 1,'name' => 'aaa','uid'=>1),
array('id' => 3,'name' => 'ccc','uid'=>3),
array('id' => 6,'name' => 'bbb','uid'=>2),
array('id' => 8,'name' => 'fff','uid'=>6),
);

$arr = array( 

array('id' => 1,'name' => 'aaa','uid'=>1), 

array('id' => 2,'name' => 'bbb','uid'=>2), 

array('id' => 3,'name' => 'ccc','uid'=>3), 

array('id' => 4,'name' => 'ddd','uid'=>4), 

array('id' => 5,'name' => 'ccc','uid'=>3), 

array('id' => 6,'name' => 'bbb','uid'=>2), 

array('id' => 7,'name' => 'bbb','uid'=>2), 

array('id' => 8,'name' => 'fff','uid'=>6), 

array('id' => 9,'name' => 'ccc','uid'=>3), 

array('id' => 10,'name' => 'bbb','uid'=>2), 

array('id' => 11,'name' => 'ddd','uid'=>4), 

array('id' => 12,'name' => 'eee','uid'=>5), 

array('id' => 13,'name' => 'fff','uid'=>6), 

); 

$id = array(1,3,5,7,9);


foreach($arr as $v) $a[$v['id']] = $v;


$t = array();

foreach($id as $k) {

  if(! in_array($a[$k]['name'], $t)) {

    $res[] = $a[$k];

    $t[] = $a[$k]['name'];

  }else {

    for($i=$k+1; $i
      if(! in_array($a[$i]['name'], $t)) {

        $res[] = $a[$i];

        $t[] = $a[$i]['name'];

        break;

      }

  }

}

print_r($res);
