PHP数组合并问题，二维数组合并成三位数组
(
[0] => Array
(
[id] => 5
[activity_id] => 2
[applyid] => 5
[signedtime] => 1463056411
[typeid] => 1
[name] => 王
)
[1] => Array
(
[id] => 6
[activity_id] => 2
[applyid] => 5
[signedtime] => 1463066411
[typeid] => 2
[name] => 王
)
[2] => Array
(
[id] => 8
[activity_id] => 2
[applyid] => 5
[signedtime] => 1463066411
[typeid] => 4
[name] => 王
)
[3] => Array
(
[id] => 9
[activity_id] => 2
[applyid] => 6
[signedtime] => 1463066411
[typeid] => 4
[name] => zhang
)
)
合并后要求成为这样：
$result=Array
(
[0] => Array
(
[id] => 5
[activity_id] => 2
[applyid] => 5
[signed]=>array(
[0]=>array(
[signedtime] => 1463056411
[typeid] => 1
)
[1]=>array(
[signedtime] => 1463066411
[typeid] => 2
)
[2]=>array(
[signedtime] => 1463066411
[typeid] => 4
)
)
[name] => 王
)
[1] => Array
(
[id] => 9
[activity_id] => 2
[applyid] => 6
[signed]=>array(
[0]=>array(
[signedtime] => 1463066411
[typeid] => 4
)
)
[name] => zhang
)
)

追问
要把applyid相同的合并成一个数组。。
追答
$key = implode('-', $_arr);
改为
$key = $_arr['applyid'];
不要忘記

foreach($result as $k => $v){
$result[$k]['signed'] = array('signedtime'=>$result[$k]['signedtime'],'typeid'=>$result[$k]['typeid']);
unset($result[$k]['signedtime']);
unset($result[$k]['typeid']);
}
追问
不是这样的 要把[applyid]相同的合并成一个
