Создайте многомерный массив из результата sql-запроса

Используя этот запрос, я получаю этот массив в результате. но некоторые строки повторяются с некоторыми отдельными столбцами. то, что я хочу сделать, это взять эти отдельные столбцы в отдельный массив как многомерный массив родительского массива. Я пытался сделать это с помощью отдельной статьи Mysql group_by, но я не мог этого сделать. Я думаю, лучший способ - сделать это по php. Пожалуйста, помогите мне с этим. Благодаря MyqueryСоздайте многомерный массив из результата sql-запроса

$query = "SELECT " 
       . "a.emp_nmbr, a.emp_frstNm, a.emp_lstNm, a.emp_lclFrn, b.emp_dsgntn, b.emp_dprtmnt, b.emp_allwncs, b.emp_bscSlry, b.emp_sts, c.emp_lvsCtgry, c.emp_tknFrm, c.emp_tknTo " 
       . "FROM " 
       . "employee a " 
       . "LEFT JOIN " 
       . "emp_details b " 
       . "ON " 
       . "a.emp_nmbr = b.emp_nmbr " 
       . "LEFT JOIN " 
       . "leaves_details c " 
       . "ON " 
       . "a.emp_nmbr = c.emp_nmbr "     
       . "WHERE emp_lclFrn = 0 "; 
       . "LIMIT $page, $perPage ";

CodeIgniter модель функции для выполнения запроса.

function count_and_data($query) { 
     $query = $this->db->query($query); 
     $result = $query->result(); 
     $count = $query->num_rows(); 
     $data['count'] = $count; 
     $data['rows'] = $result; 
     return $data; 
    }

В результате массив я получаю

Я думаю, вы можете использовать цикл foreach для получения результата sql и получить нужный вам результат. – lighter

@LLL - Но как удалить повторяющиеся строки – Yasitha

Во-первых, я думаю, что ваша структура должна что-то менять. И я пишу пример кода, чтобы выталкивать одно значение ключа в массив. Надеюсь, это поможет вам. https://gist.github.com/c11c1fbbd48321354d1f.git – lighter

Это быстрый поток, который поможет вам достичь вашей requirenment.

// collect all the unique data here 
$holder = array(); 

foreach($data['rows'] as $data) { 

    // check with emp_nmbr = ophl3 
    if(($key = _finder($data->emp_nmbr, $holder)) === false) { 
     $holder[] = array(
      'emp_nmbr'=>$data->emp_nmbr, 
      .......... 
      'emp_lvData'=>array(
       array('emp_lvsCtgry'=>$data->emp_lvsCtgry) 
       .......... 
      ) 
     ); 
    } 
    else { 
     // emp_nmbr = ophl3 found now Merge Data Here.. 
     if(! empty($data->emp_lvsCtgry)) { 
      $holder[$key]['emp_lvData'] = 
       array_merge( 
        $holder[$key]['emp_lvData'], 
        array('emp_lvsCtgry'=>$data->emp_lvsCtgry)); 
     } 
    } 

} 

// Search Value in Muliti-dimentional array 
function _finder($key, $array) { 

    if(! is_array($array) || count($array) == 0) return false; 

    foreach($array as $k=>$arr){ 
     if(in_array($key, $arr)) { 
      return $key; 
     } 
    } 
    return false; 
}

Где $holder хранит все ваши уникальные данные массива.

Я чувствую, что это сделает работу, но. все еще я получаю некоторые ошибки – Yasitha

array_merge(): Аргумент # 1 не является массивом (эта ошибка два раза) Undefined index: ophl3 Обе ошибки в этой строке $ holder [$ key] ['emp_lvData'] = array_merge ($ holder [$ key] ['emp_lvData'], массив ('' => $ data-> emp_lvsCtgry)); – Yasitha

@ Yasitha вам нужно сначала проверить массив, потому что в некоторых случаях у вас нет значения в 'emp_lvsCtgry' –

Создайте многомерный массив из результата sql-запроса
