php数组操作

原数组
Array
(
[0] => Array
(
[kc_id] => 6
[signed] => Array
(
[0] => Array
(
[id] => 108
[time] => 1469232300
)

[1] => Array
(
[id] => 109
[time] =>
)

[2] => Array
(
[id] => 110
[time] =>
)

[3] => Array
(
[id] => 111
[time] =>
)

)

)

[1] => Array
(
[kc_id] => 6
[signed] => Array
(
[0] => Array
(
[id] => 108
[time] => 1469232597
)

[1] => Array
(
[id] => 109
[time] => 1469254964
)

[2] => Array
(
[id] => 110
[time] =>
)

[3] => Array
(
[id] => 111
[time] =>
)

)

)

)
组合成： Array
(
[0] => Array
(
[kc_id] => 6
[108]=>1469232300
[109]=>x
[110]=>x
[111]=>x

)

[1] => Array
(
[kc_id] => 6
[108]=>1469232597
[109]=>1469254964
[110]=>x
[111]=>x

)

)

空的用x填充

Answer 1

$array = array(Array('kc_id' => 6,'signed' => Array(Array('id' => 108,'time' => 1469232300),Array('id' => 109,'time' => ''), Array('id' => 110,'time' => ''),Array('id' => 111,'time' => ''))),Array('kc_id' => 6,'signed' => Array(Array('id' => 108,'time' => 1469232300),Array('id' => 109,'time' => ''), Array('id' => 110,'time' => ''),Array('id' => 111,'time' => ''))));

function get_array_by_key($array , $key1 ,$key2)
{
$result = array();
foreach ( $array as $k => $value) {
$result[$value[$key1]] = $value[$key2] ? $value[$key2] : 'x';
}
return $result;
}

$data = array();
foreach($array as $key => $value){
$data[$key] = get_array_by_key($value['signed'],'id','time');
$data[$key]['kc_id'] = $value['kc_id'];
}

print_r($data);

Answer 2

foreach( $data as $k => $v){
    $newdata[$k]['kc_id'] = $v['kc_id'];
    foreach( $v['signed'] as $i => $r){
            $newdata[$k][$['id']] = $r['time'] ? $r['time'] : 'x';
    }
}
