Php Laravel 5.3：阵列推送错误

我想在Laravel5.3中用json解析数据，但我得到了一条消息

未定义的属性：Illumb\Support\Collection:：$bulan

而不是：

$data[] = DB::table('data_peminjaman')
                    ->select(DB::raw("DATE_FORMAT(created_at,'%Y') as tahun ,DATE_FORMAT(created_at,'%M') as bulan,COUNT(*) as jumlahdata, DATE_FORMAT(created_at,'%m') as b"))
                    ->groupBy(DB::raw("DATE_FORMAT(created_at,'%M'),DATE_FORMAT(created_at,'%Y'),DATE_FORMAT(created_at,'%m')"))
                    ->orderBy('tahun')
                    ->orderBy('b')
                    ->get();

foreach ($data as $key ) {
    array_push($bulan, $key->bulan);
    array_push($jumlah, $key->jumlahdata);
}

你应使用：

$data = DB::table('data_peminjaman')
                    ->select(DB::raw("DATE_FORMAT(created_at,'%Y') as tahun ,DATE_FORMAT(created_at,'%M') as bulan,COUNT(*) as jumlahdata, DATE_FORMAT(created_at,'%m') as b"))
                    ->groupBy(DB::raw("DATE_FORMAT(created_at,'%M'),DATE_FORMAT(created_at,'%Y'),DATE_FORMAT(created_at,'%m')"))
                    ->orderBy('tahun')
                    ->orderBy('b')
                    ->get();

这里唯一的区别是

$data[]

与

$data

的区别

也不是：

$data[] = DB::table('data_peminjaman')
                    ->select(DB::raw("DATE_FORMAT(created_at,'%Y') as tahun ,DATE_FORMAT(created_at,'%M') as bulan,COUNT(*) as jumlahdata, DATE_FORMAT(created_at,'%m') as b"))
                    ->groupBy(DB::raw("DATE_FORMAT(created_at,'%M'),DATE_FORMAT(created_at,'%Y'),DATE_FORMAT(created_at,'%m')"))
                    ->orderBy('tahun')
                    ->orderBy('b')
                    ->get();

foreach ($data as $key ) {
    array_push($bulan, $key->bulan);
    array_push($jumlah, $key->jumlahdata);
}
