Tatasusunan di atas dibaca dari pangkalan data
Tahun di atas ialah tahun, 01 hingga 12 adalah Januari hingga Disember, dan kemudian, 16, 17, 25 adalah tarikhnya

Cara membuatnya dalam format di bawah! Tuhan tolong saya

array(
      '2017' => array(
      '04'=>array('15','20'),
      '05'=>array('05','18')，
      '11'=>array('11','19')，
     ),
    '2018' => array(
      '03'=>array('15','20'),
      '06'=>array('05','18')，
      '11'=>array('11','19')，
     ),

2017 mewakili tahun, 04 mewakili bulan, 15, 20 mewakili tarikh 15 dan 20

Answer 1

$a = tatasusunan(

        array(
            'year'=>'2017',
            'one'=>',16,17,25,27,18,27',
            'two'=>'',
            'three'=>',16,17,25,27,18,19,15,24'
        ),
        array(
            'year'=>'2018',
            'one'=>'',
            'two'=>',16,17,25,27,18,27',
            'three'=>',16,17,25,27,18,19,15,24'
            ),
        );

    foreach($a as $key => $value){
        $year = $value['year'];
        unset($value['year']);
        foreach($value as $k => $v){
            $result = explode(',',substr($v,1));
            $time[$year][$k] = $result;
        }
    }
    
    var_dump($time);
    
    最上面还有一行 $a = array(  显示不了··
