An array-related question (I feel a little difficult from my younger brother)

An array-related question (self-perception is a bit difficult) This post was last edited by mafeifan from 2013-07-10:0:33 known $ items & nbsp ;=& nbsp; array (& nbsp; & nbsp; array ('DNA _ id' = & gt; 55, 'status' is an array-related question (self-feeling a bit difficult)

$items = array(
    array('dna_id'=>55,'status'=>1),
    array('dna_id'=>55,'status'=>0),
    array('dna_id'=>56,'status'=>1),
    array('dna_id'=>58,'status'=>0),
    array('dna_id'=>58,'status'=>0),
    array('dna_id'=>60,'status'=>0),
    array('dna_id'=>60,'status'=>0),
    array('dna_id'=>60,'status'=>0), 
    array('dna_id'=>60,'status'=>0)    
);

To obtain the following results, the number, and id of the uncompleted active Records

array(
    'active'=>array('count'=>3,'ids'=>array('55','58','60')),
    'completed'=>array('count'=>1,'ids'=>array('56'))
);

There may be multiple DNA IDs. when the status corresponding to each DNA _id must be 1 or No 0, it will be placed in completed; otherwise, it will be put into active, how can I get the above results through traversal or a simpler method? share to: 55, 'status' => 1 ),???? Array ('DNA _ id' => 55, 'status' => 0... 'data-pics = ''>
------ Solution --------------------
Write like this

$items = array(
    array('dna_id'=>55,'status'=>1),
    array('dna_id'=>55,'status'=>0),
    array('dna_id'=>56,'status'=>1),
    array('dna_id'=>58,'status'=>0),
    array('dna_id'=>58,'status'=>0),
    array('dna_id'=>60,'status'=>0),
    array('dna_id'=>60,'status'=>0),
    array('dna_id'=>60,'status'=>0), 
    array('dna_id'=>60,'status'=>0),
);
$res = array(
  'active'=> array(
    'count' => 0,
    'ids' => array()
    ),
  'completed' => array(
    'count' => 0,
    'ids' => array()
    ),
);
foreach($items as $v) {
  if(!in_array($v['dna_id'], $res['active']['ids'])) $res['active']['ids'][] = $v['dna_id'];
