轉換數組元素轉換成以逗號分隔的數組中的PHP

Question

我有這種類型的數組，我想隱蔽了一些要素，以逗號separeted

Array 
(
    [0] => Array 
     (
      [tution_provider] => sd 
      [app_subject_name] => KE2-Management Accounting Information 
      [exam_activity] => 734 
      [icasl_no] => 1746828 
      [app_subject_id] => 1013 
      [exam_session] => 000091 
      [id] => 724 
     ) 

    [1] => Array 
     (
      [tution_provider] => sdfsdf 
      [app_subject_name] => KE3B-Fundamentals of Law 
      [exam_activity] => 734 
      [icasl_no] => 1746828 
      [app_subject_id] => 1016 
      [exam_session] => 000091 
      [id] => 725 
     ) 

    [2] => Array 
     (
      [tution_provider] => sdfsdfsdf 
      [app_subject_name] => KE4-Processes, Assurance & Ethics 
      [exam_activity] => 734 
      [icasl_no] => 1746828 
      [app_subject_id] => 1017 
      [exam_session] => 000091 
      [id] => 726 
     ) 

) 

我想離開從

放

app_subject_id

作爲逗號分隔的數組。我怎樣才能做到這一點？

這是出放，我想

陣列（[0] => 1013 [1] => 1016 [2] => 1017 [3] => 1013 [4] => 1016 [5 ] => 1017）

Answer 1

$array = array_column($array, 'app_subject_id'); //Get an array of just the app_subject_id column 
$array = implode(',', $array); //creates a string of the id's separated by commas 

輸出：

1013,1016,1017 

Answer 2

甲一個襯裏將做到這一點：

$appSubjectId = implode(',', array_column($originalArray, 'app_subject_id'));

最後我已經這樣做了，感謝您的大力支持。

 $subjctss = $myarray; 

    if (!empty($subjctss)) { 

             $subid_arr = array(); 
             foreach ($subjctss as $values) { 
              $app_sub = $values['app_subject_id']; 
              $subid_arr[] = $app_sub; 

              echo '<ul><li>' . $values['app_subject_name'] . '</li> 

          </ul>'; 
             } 
             if (!empty($subid_arr) && is_array($subid_arr)) { 
//           $app_sub_comma_seprated = implode(',', $subid_arr); 
              print_r($subid_arr); 
             } 
            }
