這就是數組的最終輸出應該是這樣的$dataToReset = array (    'email_address' => $subEmail,    'status' => 'subscribed',    'interests' =>         array (        '1111111' => true,        '2222222' => true,        '3333333' => true,        '4444444' => true,        '5555555' => true,    ));我想更換以下部分'interests' =>     array (    '1111111' => true,    '2222222' => true,    '3333333' => true,    '4444444' => true,    '5555555' => true,)$interestsAdd有了這樣的變量$dataToReset = array (    'email_address' => $subEmail,    'status' => 'subscribed',    $interestsAdd);我得到的值和我嘗試過的值如下，但沒有成功！if ($form_data['lbu_multilistsvalue'] !== ''){        $groupsSelected = $form_data['lbu_multilistsvalue'];    $selectedGroups = array_fill_keys(explode(",", $groupsSelected), true);    $interestsAdd = ['interests' => $selectedGroups];} else {    $interestsAdd = '';}
