$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);

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';
    }
}

追问syntax error, unexpected '[', expecting variable (T_VARIABLE) or '$'

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