hmm you mean index array instead of associative array ? – Madhawa Priyashantha May 30 '17 at 03:31 — Madhawa Priyashantha, May 30 '17 at 03:31

$array = array_column($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

Output:

1013,1016,1017

A one liner will do it:

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

     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);
                                        }
                                    }
